This is an interesting article debating the different types of communication that can be used over a long distance, and as they distance moves further and further, the different types of communication drop off or become part of an infrastructure. As engineers battle with this problem, knowledge of how radio frequencies and applications becomes paramount.
As offshore windfarms are built further and further from land, alternatives to conventional VHF communications are going to be required
A cornerstone of any major project is clear communication between all parties. As we move windfarm construction further offshore, maintaining efficient voice and data communications becomes essential. With many projects now being constructed beyond the range of VHF radio and cellular telephone, such as a Gemini or Dudgeon offshore windfarms, crew transfer vessel (CTV) operators and their clients are experiencing challenges achieving practical and affordable offshore communications. My experience on two far offshore projects in the last 15 months has shown that creative thinking can work together with existing equipment such as TETRA radio to reduce the risks and stress that poor communications can generate.
Communication solutions on offshore windfarms depend on the phase that the operation is in, the size of the project and the distance from shore. Many smaller, older windfarms rely on VHF radios to communicate between shore and vessel and shore/vessel and work team on the turbines. However, VHF is limited in range being a line-of-sight system, and the signal has trouble penetrating structures such as wind turbines due to the Faraday cage effect. Conventional cellular telephone coverage is also possible on nearshore sites, with some windfarms installing a cellular mast within the windfarm. Vessels at anchor off the Dutch port of IJmuiden can thank the windfarm industry for good connection when waiting for a pilot if they have contracts with the provider KPN.
When moving further offshore, luxuries such as a cellular mast will not be installed during the construction phase, and it is most likely that VHF radios will not be sufficient. It is common for the developer to install a TETRA radio network â similar to those used by national emergency response services such as police and fire departments.
TETRA, or terrestrial trunked radio as it is properly termed, is a secure network allowing one-to-one, one-to-many and many-to-many communications. This means that the marine controller can speak directly and privately to one party or to the entire offshore spread depending on what is needed. It transmits on a lower frequency than VHF so covers a greater range. This still is not enough to cover the distances experienced on far offshore windfarms. If multiple base stations are used, each base station can then automatically rebroadcast a message thus expanding the network coverage. On a recent construction project, it was found that there were communications blackspots in the area of the sea passage from the base port to the site. This was later eliminated by fitting full base station units rather than just handheld transceivers on the CTVs. The CTVs then became vital links in the communications network and ensured the blackspots were reduced or eliminated altogether.
TETRA has many other advantages, including the ability to penetrate the tower of a wind turbine, and calls are not dropped when moving between base station carriers due to the network configuration. This is especially important if vessel-carried base stations are relaying far offshore. The network is also secure, which ensures that commercially sensitive information cannot be intercepted. With the one-to-one mode, it also means that managers can have detailed conversations on sensitive subjects.
However, anecdotal information received from vessel crews in the field appear to indicate that TETRA, although a good system, is not foolproof. One vessel master reported that, after 15 months on site, they still had blackspots with TETRA and sometimes have to use the cell phone application WhatsApp to request that turbines be started or stopped so that he can land a team.
TETRA does not solve the operational problems experienced by vessel-operating companies who require frequent voice and data communication with the CTVs to ensure a smooth delivery of service. As most sites far offshore are outside of cell phone coverage and clients demand that daily reports are issued on time, creativity is needed. There is a simple solution that could solve all of the communication problems far offshore â installing VSAT satellite communications on each CTV, which allows instant telephone and data transfer.
However, the practicalities of chartering in todayâs windfarm industry eliminates this option, as the client will not want to pay for installation and operation, and a vessel owner cannot afford such a luxury. Charterers therefore need to make a decision: either they assume responsibility and the costs for practical workable satellite communications on their vessels or look for practical alternative solutions to deliver what is needed far offshore.
One practical solution to maintain communications between the marine co-ordination centre and vessels is to step back a generation and use medium frequency/high frequency single side band radios, which are common equipment on larger CTVs and is standard on service operation vessels (SOVs) or installation vessels.
When used in conjunction with the digital selective calling (DSC) function of the GMDSS standard, voice communications can be maintained at long distance without operating cost. Unfortunately, current guidance for the marine co-ordination in windfarms as found in the G9Â Good practice guideline:Â The safe management of small service vessels used in the offshore wind industryÂ does not yet consider marine co-ordination and communications in far offshore windfarms.
Another practical solution to improve data communication is to install powerful WiFi antennas on the decks of SOVs and other major offshore assets to allow CTVs to have internet access when they are in close proximity. CTVs can then download passenger manifests and weather reports and upload the daily progress report and synchronise planned maintenance and email systems.
CTVs spend considerable time in close proximity to the SOV during passenger transfer, bunkering or waiting for the next assignment, and it is relatively easy to set up the computers to connect and synchronise without operator input, thus reducing the risk of distraction. SOVs should be designed with space for CTV crews to use as a secure office so that laptops can be left connected to the network. In this way, crews can have two computers and prepare work when on shift, transfer via a data stick and upload when they go off shift.
One of the most effective tools that we have identified is WhatsApp, which seems to require very low signal strength to connect and transfer brief messages. On recent projects, we have found that most vessel/office communication occurs in this medium, including fault finding and incident reporting and investigation. Crews have found it quicker to video a CCTV system playback and send via WhatsApp than download the CCTV video and send it via a file transfer service. As synchronising an electronic planned maintenance system offshore is very time consuming, our superintendents have taken to sending the worklists via WhatsApp to the vessels who then confirm back with text or images when a job is complete. The superintendent then does the PMS administration from their office with the advantage of high speed network connections. Experience with WhatsApp has led me to believe that agile, low data applications will form part of the future of offshore communication.
Far offshore projects have moved from planning and dreaming to reality. However, effective and cost-efficient communication solutions have not moved with them. Like most challenges with far offshore windfarms, there is no single solution, but experience has shown that, with creativity and flexibility, projects can communicate with their teams and operators can manage their vessels.
Better equipment earlier on in the construction phase, such as MF/HF radios in the MCC and on the vessels, TERA base stations on the vessels and open deck WiFi on construction assets will all assist in improving safety and reducing stress while ensuring that unnecessary costs are not incurred.
This news is making quite a buzz within the stock market forums, With two of our big players in our industry set to merge, this is huge news! Yes, Sepura have had their problems this year and Hytera have increased their market share, but we are not sure is this is good news or bad?
Another Asian corporation is set to hoover up a Cambridge UK technology company in a state of financial flux.
Communications technology business Sepura confirms it is in talks with Chinese company Hytera Communications Corporation Ltd.
It will be an all-cash deal but the acquisition price will be moderate because digital radios company Sepura is in a mess because of cash liquidity issues.
Sepura revealed the takeover talks after its share price spiked more than 25 per cent having nosedived in recent times due to cashflow issues and order delays.
Hytera is a world leading solution provider of professional mobile radio communications and operates globally.
Late today, Sepura issued a statement on London Stock Exchange confirming it was in preliminary talks with Hytera regarding a possible offer for the entire issued and to be issued share capital of the company.
Hytera confirmed to the Sepura board that any offer was likely to be solely in cash.Â The usual caveats were issued that there was no certainty any deal would go through and shareholders would be updated on new developments.
Founded in 1993 in Shenzhen, China, Hytera has grown to be a key player in the PMR (Professional Mobile Radio) communication industry with a large customer base in more than 120 countries and regions across the world.
In China, Hytera’s market share ranks first among Chinese manufacturers while globally Hytera has reached second place in the overall terminal category.
As one of the few corporations that masters TETRA, DMR and PDT technologies, and produces all series of products and solutions of all these mainstream digital protocols, Hytera leads in the draft of digital trunking standard in China.
Its acquisition of the Rohde & Schwarz TETRA business in August 2011 further strengthened its competitive edge in TETRA market.
Hytera has established a global sales network with 30 branches in the US, UK, Germany, Australia, Brazil and other territories and through Â 600+ partners across the world.
Hytera has an R & D team of over 1200 engineers in five research centres.Â Sepura won the Business Weekly Awards Business of the Year title in March after a record-breaking
2015 but hit liquidity problems this summer and has temporarily lost its CEO Gordon Watling to ill health.
It is surprising how in a crowded, noisy environment you can still create your small world. This is one of the most amazing changes that have been made by headphones. Small devices with a big impact on the world are the only way to describe headphones. In the past, the only way to listen to music was through devices that allowed everyone to listen to music at the same time. With the introduction of headphones, you donât have to bother everyone with your music; you can create your space and enjoy listening to what you like directly to your ears.
Early headphones were mainly used for communication purposes. The birth of headphones in early 19th century was purely for communication and professional uses. It is strange how the creator of headphones Nathaniel Baldwin didnât have the musical concept in mind. The uses of headphones at this time were purely for professional uses by people in the army and also church coordination.
Discovery of stereo phones for music was a big break in the mid-19th century, the whole perspective of headphones changed from professional use and they were given a musical touch. The musical evolution changed the concept of headphones, and this gave birth to the stereo phone technology to cater for musical fanatics. This was when headphones specifically for music were created, but they were expensive.
Light weight portable headphones were discovered in the 1980s there was a big break after everything went mobile. The headphones now become lighter, and you could see youngsters carrying them around. The growth of the pop culture at this time might have had a huge impact on how people wanted to listen to their music and this made headphones grow more. The sound quality becomes better at this time.
Modern fashion statement headphones are now common to bring out personality and social standards. The headphones that we have now are bringing the fashion statement in mind. The unique design and the big brand names like Beat by Dre are bringing a new perspective on the way we view headphones. The technological advancement is sound quality is now improving due to latest technological innovations.
Good sound quality and faithfulness is one of the main benefits of headphones. We all agree listening to music through headphones feels good compared to listening through loudspeakers. The reason for this is quite listening simply. Music from headphones has no interference from external forces and especially if you are listening to music through quality headphones.
The concentration at work is now better with headphones. With the use of headphones, it is now possible to get peace of mind and keep up concentration whilst working. It is surprising how music takes us to a new world where we can be able to reflect and focus on the work we are doing. This is the reason why you will find people working in jobs that need a high level of concentration using headphones all the time.
Peace of mind and calming stress is a major reason why many people use headphones. Music is therapeutic, and it works wonders in relieving stress and restoring peace of mind. Listening to music through external speakers is good for entertainment but not necessarily for healing. There is something special about listening to music through headphones because it brings calmness and brings back peace of mind.
Privacy is one thing that many people seek in the crowded and noisy world. If you want to maintain privacy, then you can easily escape in your headphones and get the privacy that you need. People around you will understand that you need privacy and allow you to have your solitude.
The uses of headphones are now limitless, and they go beyond just for the sake of entertainment and communication purposes.
Music lovers get lost in their headphones for hours listening to music without interrupting the rest of the world with the type of music that they love. Using headphones, music lovers can get the sound effect that they want from the headphones through sound effect settings.
Transcribers who translate audio content into text need headphones to be able to listen to what they are typing. This is one of the most common professional use of headphones. Other people like pilots, recording artists and also the military use headphones in their job.
You can find a whole ton of walkie talkie headsets at this amazing store headsetonline
Intel just announced its own virtual reality headset called Project Alloy, a VR competitor to theÂ Oculus Rift,HTC ViveÂ and the forthcomingÂ PlayStation VRÂ headsets. But what separates the Alloy from the pack is that itâs completely wireless (the wire above is for capturing video for the demo) and it should give you complete spatial awareness without all the dongles the Rift and Vive currently require.
It does this using two of Intelâs RealSense cameras to continuously map your environment. It can even map your hands.
Intel calls the idea âMerged Realityâ, essentially combining inputs from cameras around your environment into a virtual world. And Intel was able to pack everything â the processor, sensors and controllers â into one cord-free headset.
During Intelâs demo, however, the RealSense camera didnât seemÂ quiteÂ as fluid as youâd hope, especially if itâs your primary means of reacting to the digital world around you. Intel says that its hardware will be open source in the second half of 2017 (ugh), so the headset wonât be available anytime soon. Intel is also working with Microsoft so Alloy can run Windows Holographic, the softwareÂ which powers Hololens, according to Microsoftâs Terry Myerson. Microsoft says that Windows Holographic will also be released in an update for all Windows 10 PCs next year.
In the modern world the army has to have perfect communications, from coordinating attacks to communicating with other platoons, on the battlefield it really could mean the difference between life and death. This article plans to find the next Military radio.
U.S. ArmyÂ tactical radio officials plan to launch a competition for a new handheld radio next year that would give soldiers twice the capability of the current Rifleman Radio.
The Army currently uses the single-channel AN/PRC 154A Rifleman Radio as its soldier handheld data radio. It runs the Soldier Radio Waveform, which small-unit leaders use to download and transmit maps, images and texts to fellow infantry soldiers in a tactical environment.
If they want to talk to each other, they often rely on another single-channel handheld — the AN/PRC 148 MultiBand Inter/Intra Team Radio, or MBITR, which runs the Single Channel Ground and Airborne Radio, or SINCGARS, for voice communications.
The Army plans to release a request-for-proposal in 2017 for a two-channel radio that will allow soldiers to run the Soldier Radio Waveform, or SRW, for data and SINCGARS for voice on one radio, according to Col. James P. Ross, who runs Project Manager Tactical Radios.
The change will mean that soldiers will no longer need the 148 MBITR and be able to rely on the new, two-channel radio for both data and voice communications, Ross said.
“We know industry can meet our requirements. â¦ We know it’s achievable,” he said.
The move represents a change in strategy for the Army since the service awarded contracts in 2015 to Harris Corporation and Thales for a next-generation version of the Rifleman Radio.
“We went out with a competition for the next generation of the [Rifleman Radio]. Two companies, Harris and Thales, competed,” Ross said. “We went through testing, and we were on the verge of being able to buy more of them when the Army said, ‘Our strategy now is two-channel.’ ”
The Army had planned an initial buy of about 4,000 Thales AN/PRC-154B(V)1 radios and Harris AN/PRC-159(V)1 radios, according to Army program documents for fiscal 2015.
“We will not be taking action on those,” Ross said.
The current Rifleman Radio was developed as part of the Handheld, Manpack, Small Form Fit, or HMS program. HMS radios are designed around the Army’s tactical network strategy to create secure tactical networks without the logistical nightmare of a tower-based antenna infrastructure.
It’s also a key part of the Army’s Nett Warrior system. It hooks into an Android-based smartphone and gives soldiers in infantry brigade combat teams the ability to send and receive emails, view maps and watch icons on a digital map that represent the locations of their fellow soldiers. The concept came out of the Army’s long-gestating Land Warrior program.
The Army purchased about 21,000 Rifleman Radios under low-rate initial production between 2012 and 2015.
Army officials maintain that are enough single-channel, handheld radios already produced under the low rate initial production that are sitting waiting to be fielded. The service plans to field another two brigade combat teams per year with the single-channel Rifleman Radios through 2019.
The Army will conduct testing of two-channel radios in 2017 and early 2018 and then down-select to one or two vendors sometime in 2018, Ross said. Operational testing is scheduled for 2019 and fielding will begin in 2020 if all goes as planned, he added.
For now, the Army intends to field four BCTs a year with two-channel handheld radios, Ross said.
Small-unit leaders would then be able to retire the MBITR radio from their kit — a weight savings of about three pounds, according to Army officials at Program Executive Office Soldier.
“One thing the PEO Soldier is very passionate about is weight — driving that weight down that the soldier carries,” said Lt. Col. Derek Bird, product manager for Ground Soldier Systems, which helps oversee the Nett Warrior program.
“If we can cut three pounds off a soldier by taking two radios and shrinking it to one â¦ that is a big deal.”
This is an excellent story about how hearing protection is sometimes be essential, and when youâre on the shooting range it has to be vital. But it is important to get the right set of headphones that will protect your hearing sufficiently. Lessons can be learnt from this excellent case study.
There is no doubt that we all take our senses of sight, smell, and hearing for granted as long as we are strong and healthy and everything is working well. When we are young we tend to believe that we are indestructible and readily adopt the idea that âit will never happen to me.â Consequently, we can develop some bad habits and be a little loose when it comes to preventative measures for almost anything.
I know because that was my attitude at thirty years old when my eye doctor made a comment in passing that my eyes were perfect, but the chances are I would be needing reading glasses by the time I was 50. I scoffed, but you could almost have set your watch by it because by the time I was in my late 40âs my arms started to get shorter when it came to reading, tying on fishing lures and other things that required scrutiny up close. At 50 I was wearing reading glasses.
Growing up I never bothered too much about wearing ear protection. When I was plinking it was with a .22 rifle that only put out a little noise if you were the shooter so the thought of hearing protections seemed ludicrous. When hunting I do not know if I have ever heard my firearm discharge and beside that unless I was dove hunting I seldom shot too many shots anyway.
The change of heart came when I started shooting on an indoor range, while in the Air Force. I noticed after shooting a few rounds with my .22 caliber, Ruger Single Six that my ears would ring for a while afterward. One night a grizzled old Master Sargent suggested I wear ear protectors or take a chance of damaging my hearing. I took the recommendation to heart and have been wearing them ever since. The result has been that after many years of shooting .22âs, large caliber handguns, rifles and shotguns my hearing is still intact and working well.
Shooting is not the only activity that can cause hearing problem as any loud noise can damage your hearing. The intense vibration caused by loud noises can injure or destroy the hair cells inside the cochlea, so they no longer function to transmit nerve impulses to the brain. If that happens, you will experience hearing changes.
Hearing protection is needed anytime one is exposed to sounds above 80 decibels (dB). Normal human conversation runs about 30 to 35 dB. At its peak level, the sound of a 12-gauge shotgun is about 140 dB. 9mm runs around 159 dB and a .38 special with a six-inch barrel is about 156 dB, a .22 LR pistol with the same length barrel 140, an M-16 is about 154, a .45 ACP pistol is 155, and a .357 Magnum revolver is 164. All of them are around double the safe sound level. Just to be on the safe side I used to wear muff type hearing protectors and usually ear plugs also when on the range.
For range use today there is an array of muff style hearing protectors. The new style that I now use have not only hearing protection, but also hearing enhancement. The controls on each ear can be tuned to match your individual optimum hearing and increase the volume up to eight times normal. So when the range master gives a command or when you are speaking with a companion on the shooting line you can speak in a normal voice and hear them as well or better than without the power muffs. Yet when you shoot the sound activated compression circuit reduces the sound from the shot to a noise reduction rate of 24dB.
This is very important on a shooting range because I have missed range commands in the past from the range master simply because I could not hear them through my hearing protection.
The new muffs I use are from Walkerâs but they offer many other styles in their Game Ear series. These are unlike the muff style protectors as the bulk of the unit fits behind your ear with an earpiece that fits inside your ear, the unit weighs less than one fourth of an ounce and can be used with or without glasses. These too can be fine-tuned to your specific hearing, allow you to turn the volume up to magnify sounds from five to seven times and still reduce the sound of the shots to a rating of 29dB.
The ability to custom tune the devise to your hearing as well as adjust the volume up on these models will enable the hunter to more readily pickup games sounds in the woods. Sounds like a squirrel jumping through the trees or when their belly slaps a tree when they jump from one to another. It will help the hunter pick up the minutest sound of a deer brushing by limbs or the whisper of them walking through leaves or disturbing a rock.
So now there is really no acceptable reason not to wear hearing protector and if you get a good set it may even enhance your chances of bagging some more game.
A Walkie Talkie is a handheld receiver or portable radio. Walkie talkies come in a pair and they communicate quietly with one another using radio waves, on a single shared frequency band.
Almost all of us grew up with walkie talkies. As children, and especially before the age of mobile phones and technology, we all had a pair and played with them in our gardens.
Walkie talkies have made a comeback. Or maybe they never really went out of style but now theyâre sophisticated.
Each unit is battery powered and has an antenna for sending and receiving radio wave message. There is a transmitter / receiver and a loudspeaker. The loudspeaker doubles up as a microphone. There is a button that you push to talk, pretty much the same way that an intercom works. Some more sophisticated walkie talkies have separate loudspeakers and microphones; it just depends on what you need the walkie talkie for.
Walkie Talkies with noise cancelling headsets
Technology has changed so much and become so much more sophisticated. In the old days, think of the crackles that came with walkie talkies. It was often very difficult to hear what the other person was saying. But a pair of noise cancelling walkie talkie headsets will reduce or remove any unwanted sounds by using active noise control. Note that this is very different from passive headphones which use technique such as soundproofing. Noise cancelling is not soundproofing.
Our worlds are busy and we become bombarded and overwhelmed by everything around us. We need to listen to some things, but we want to cut out others. Noise Cancelling allows us to do this, while still allowing us to listen to the things we want to listen to at the volume we want them.
Pros of a walkie talkie headset?
Remember when we used to listen to music really loud so we could block out all the other external noise? You don’t need to do this anymore. walkie talkie headsets will block out most excess or excessive sound, or the ones you want blocked out anyway. You can now listen to your music at the volume you want, which does not need to be crazy, and the other external sounds (baby crying, man snoring next to you) will be blocked out anyway. Finally, you can listen to and enjoy music in the way you want to enjoy it, at a natural volume. You can hear the fabulous music, have a rich listening experience, and still not be disturbed by chatter around you.
Noise cancelling headphones are fabulous for when you travel or commute. You may be the kind of person who gets on a plane and train and chats to everyone around you. But you may be more solitary and want to sit down and zone out. You can do this easily with a walkie talkie headset. The beauty is that on a plane you wonât hear the noise of the aircraft or its passengers, but you will still hear the safety announcements.
Itâs really easy to work in a noisy environment with noise cancelling headphones. You can focus easily without being disturbed and can make use of any space, productively. You can even go and study your history while at a party or in a restaurant. It is also a good idea to use them at home, while studying for exams or so; they cut out the excess noise and you can focus totally on your work.
Students used to turn up the volume of their earphones in order to cut out the outside worldâ. But with a walkie talkie headset they are finding it is easier to study when music is at a lower volume and when the outside distractions have been eliminated.
Cons to noise cancelling headphones?
There are always cons to everything. Some parents may say they would prefer no headphones at all. They like their children to be available and to engage more and talk more, but we know this is the way of the world. Everyone uses headphones; parents included/ Use them in moderation of course, but still be sociable and take time out in the day, be headphone free, and engage.
Noise cancelling headphones are not very cheap and are in fact possibly even ten times more expensive than ordinary headphones. However, like anything that costs money, they will last for a long time and are super reliable. They may cost more money but will ultimately give a much better noise-free experience.
Lots of research has gone into the design of these special noise cancelling headphones. Each set consists of inner components that cancel out the disturbing external sounds. Ordinary headphones do not have these components, i.e., you cannot cut out the outside sounds. It is quite obvious then, why noise cancelling headphones are more expensive.
These internal components also use up a lot of power. The power can come from internal replaceable batteries or they can be rechargeable. means they are heavier than ordinary headphones. Not all sets carry their own power supply. The ones that are rechargeable are lighter, but they can drain the devices they need to plug into for power.
The quality of sound when using a noise cancelling walkie talkie headset can be compromised. It is unusual though and it is only the most sensitive of ears that would pick this up. There have been very few complaints of a tinny almost mechanical sound, but these complaints are few and far between.
Not all sounds are blocked out by a walkie talkie headset, although we did mention this under pros as well. It is never possible to cancel out all external sounds, but we still need to be able to hear police sirens, pilot announcements or the high pitched screaming of your next door neighbor. All every day external sounds though are muffled and definitely much quieter, and the sounds that you don’t need to hear, are gone.
When you think of a spy earpiece, the first thing that comes to mind is inspector gadget or Mission impossible, well it does for us anyway. But there are real world applications for these earpieces are wide. As this article explains, when you need a little help with prompts on a big presentation or you need to receiveÂ instructions during a lecture, then a micro earpiece could be the answer.
This device originally developed for covert operations is now made available for the public to use. Each earpiece kit can provide a way for you to transmit and receive audio information without anybody in the room knowing. Whether you want to receive pre-recorded messages or information from another party to assist you during your presentation / interview or speech, the earpiece can be set up with your phone, audio recorder, radio, or MP3 player to send the message to your earpiece , placed in your ear channel so that it is undetectable .. All kits also include a built in microphone so that you can engage in 2 way conversation should you wish
So how does it work?
The key is the inductive transmitter that will transmit audio from a phone / mp3 player to the earpiece. The transmitter itself is available in many forms. For example the transmitter may be included within a neckloop to be worn around the users neck, this may connect to your phone or mp3 player via its earphone socket. Or you may have a Bluetooth are often included in everyday objects such as a pair of glasses, a Pen or even a bluetooth watch. The transmitter acts as the aerial for reception and signal transmitter from phone to earpiece. At the same time, output sound picked up by the tiny microphone attached to the neckloop / pen / glasses is sent through your phone just as if the user is talking directly into it.
How to Use The Spy Earpiece?
Depending on what kind of information you wish to receive the earpiece can be set up to suit. For example during a presentation or speech you may wish to pre-record your speech or presentation on an mp3 player, then play it back to yourself during the presentation / speech. Or simply record a simple prompt for each point you would like to make. You could then connect up your mp3 player to an inductive neckloop included in most earpiece kits, and wear a spy earpiece. So long as the battery is inserted into the earpiece you will hear the audio from your mp3 player in the earpiece.
Alternatively you may prefer to have a team prepped in another room to assist you during your speech. This can be achieved by simply starting a mobile phone conversation with your team just before the speech starts. You would then need to either connect an inductive neckloop to the headphone output of your phone, or pair your phone with a bluetooth induction neckloop / pen / glasses. Insert the earpiece into your ear making sure the battery is inserted correctly. Your team should be able to hear your speech in real time over the phone, and can give you tips in your earpiece along the way. The same may apply in an interview situation, you may wish to have a third party issue you advice during your interview.
Lets not forget the original intention of the Spy Earpiece which is for security and covert surveillance. The Spy Earpiece excels in these situations where the requirement is for a security operative to communicate covertly.
The key to success is in the careful planning and preparation so that everything runs smooth.
The way I see it, when the challenge is great and the results mean everything, why not try the Spy Earpiece and take the risk out of the equation?

Now itâs not the usual field that we cover, but it hit our radar. How many times have you seen an enthusiastic presenter or an excited contestant on TV drop their radio mic and crawl around on the floor, trying to pick it up! Well when a costume designer and a sound man get together then things get designed, and why this hasnât be invented before is beyond us, but it looks like an idea that could take off. Read the full article here.
Sound recordist Simon Bysshe and costumier Laura Smith have combined their knowledge and expertise to create URSA Straps, a unique range of low profile body worn straps designed to conceal radio microphone transmitters.
Officially launched this month and now available in the UK and Europe, URSA Straps are made from a specially developed bonded fabric that is ultra-slim and provides excellent stretch, comfort and breathability. Each strap incorporates a pouch to keep the transmitter locked in place and a cable pocket for managing excess microphone cable. URSA Straps are available in black, beige and brown skin tone colours and can be worn around the ankle, thigh or waist.
Bysshe and Smith developed URSA Straps after listening to numerous artists express discomfort while wearing radio mic straps. Traditional thick neoprene or elastic straps can irritate the skin, become soaked in sweat and are often impossible to disguise under figure hugging costumes.
âIt was obvious that a better way of discreetly securing transmitters was required,â Simon Bysshe explains. âAs a boom operator I had worked with many artists who disliked wearing transmitter packs because their associated straps could restrict movement and become uncomfortable. In some cases they had simply refused to wear them.â
Laura Smithâs knowledge of costume making proved invaluable as she was able to construct prototypes and identify the exact fabrics required to suit the needs of costume, artists and sound departments.
âAfter many months of research we decided to create our own unique hybrid fabric by fusing two stretch fabrics together,â Bysshe explains. âThis resulting fabric is just 1mm thick and much lighter and softer than any other fabric of its kind. Crucially we incorporated a hook Velcro compatible outer surface that allows the straps to be securely attached to themselves at any point.â
Bysshe tested the new straps while working on the second series of Sky AtlanticâsÂ The Tunnel. Lead actress ClÃ©mence PoÃ©sy was an immediate convert and provided valuable feedback to help develop the product. Bysshe has subsequently used URSA Straps on the third series ofÂ Peaky Blinders. The USRA Thigh straps were particularly popular with the cast members who found them secure, light and comfortable. The fact they can be worn around the thigh as opposed to the waist made them invaluable for use with the period costumes.
âWith URSA Straps we have created such a comfortable low-profile solution that artists often forget that they are wearing them. Now we have to make sure that actors remember to take them off before they leave!â Bysshe adds. âThe straps can be washed and re-used every day for many months. Our Thigh straps are particularly popular as they are designed to not slip down the leg. We achieved this by bonding on a strips of Polyurethane gripper to the inside of the straps.â
Outside film and television, URSA Straps are also proving popular with dancers who need to receive audio cues during a live performance. Using waist or thigh straps the sound team can easily conceal a receiver pack on their bodies without restricting movement or compromising the look of their costumes. URSA Straps have also developed a Double-Pack strap allowing artists to wear two packs on one strap.
Oscar-winning production sound mixer Simon Hayes was an early adopter of URSA Straps and describes them as a total game changer for his team.
âURSA Straps allow us to rig radio mics on costumes previously thought to be unmicable. Tight dresses, sportswear, stunt harnesses â they can all be easily miked using low profile URSA Straps. These straps are so popular with the actresses I work with that many have asked to keep theirs at the end of the production.â
URSA Straps are suitable for a variety of wireless transmitters including Lectrosonics, Zaxcom, Wisycom MTP40 and Sennheiser 5212. Two different pouch sizes are available to ensure optimum fit. Three different waist sizes are available: small, medium and large.
âInitially Laura and I were making the straps by hand in our garage,â Bysshe says. âWhen we realised their potential we scaled up production by taking on two experienced manufacturing firms in Leicester. Our launch has been a huge success with orders coming in from all around the world! We are now on our third large production run and expanding our market into Theatre, Concerts and Outside Broadcasts.â
