![]() We see a lot of people that say they no longer need a traditional speaker mic. and switch to a lighter and more flexible communication setup. Using the CHOICE™ PTT allows you to ditch your speaker mic. it turns off the loudspeaker on the speaker mic. ![]() When you use an earpiece connected to your speaker mic. If you currently wear an earpiece that connects directly to a speaker mic, the CHOICE™ PTT/Mic works the same way(no speaker). The CHOICE™ PTT/mic has a side PTT (Push-To-Talk) and a premium direction microphone on the top with a Braided Fiber Cloth™ cord going to your radio. ear 360™ earpieces (with a 3.5mm connector). ![]() Other PTTs can be strapped to motorcycle handlebars or around the user’s wrist.The CHOICE™ PTT/mic has a 3.5 audio port and will work with all N PTT switches come in a variety of shapes and sizes, from tiny in-glove finger PTTs that wrap around the user’s finger to full-surface MOLLE-spec PTTs that can be clipped to a vest. The PTT is sometimes preferred by users over the VOX function, since gunfire, coughing, and traffic noise can all be loud enough to trigger accidental transmission, as can a transponder rubbing against the neck. Throat mics are often connected to a PTT (push-to-talk) switch that in turn feeds into a two-way radio (in mobile phone versions, the PTT functions as an answer/end call button). Most throat mics use a single-ear silicon acoustic coil to channel sound from the speaker on the neck strap, but there are also models that use helmet speakers, earbuds, and ear-hook earpieces. In addition to the quality of the transponder and the radio, users should consider which type of earpiece best suits their operational requirements. It is best to pair throat mics with high-powered professional grade radios. Recreational radios are generally too low-powered to transmit the sound from a throat mic clearly and with enough volume. The quality of throat mic transmissions also depends greatly on the radio. Some of the latest models incorporate a more sensitive transponder, allowing it to more effectively pick up vibrations. Many throat mics have only one transponder in order to better balance transmissions. Of course, the most important determinant in the quality of throat mic transmissions is the transponder itself. Wearing the throat mic slightly loose will improve transmissions. The user should also be careful to properly tighten the throat strap if strapped too tightly, the pressure on the transponder from the neck is too great to absorb the vibrations. 5’’ to 1’’ from the center of the throat. The sweet spot is different for everybody but generally located. To optimize sound quality and volume, the user should find his or her personal transponder “sweet spot” that balances clarity and volume. Placing the transponder too close to the center, however, will increase muffling. As a rule, the closer to the center of the throat the transponder is, the louder the transmission will be. In addition, the clarity of the transponder’s transmissions can be affected by the amount of adipose tissue and facial hair on the user’s neck. ![]() Also, because the transponder rests on the throat, sounds that are naturally generated in the nasal cavity and by the tongue and lips are muffled. Throat mics tend to cost more than conventional microphones. There are a number of disadvantages as well. Because they do not interfere with the use of other equipment and are highly adaptable to a variety of extreme acoustic environments, throat mics are ideal for a wide variety of tactical and recreational applications. They can be worn with helmets, masks, HAZMAT suits, and full-face breathing apparatuses. Throat mics have the additional advantage of being non-obstructive. Depending on the quality of the transponder, a throat mic can also pick up whispers, allowing the wearer to communicate covertly without giving away his or her position. Throat mics, however, pick up only vibrations from the throat, and are insensitive to background noise and wind turbulence. Boom mics cannot function in high-noise and high-wind environments because they are sensitive to all sounds carried by the air. The transponder sits on the user’s neck, absorbing the vibrations generated by the larynx and turning them into electronic audio signals, thereby transmitting sound directly from the throat.Ībsorbing vibrations directly from the throat confers a number of advantages over conventional microphones. At its most basic, the throat mic consists of either one or two coin-sized transponders mounted on a strap, a wired connection to a radio or phone, and earphones. The throat microphone, also known as a laryngophone, is a type of contact microphone that was first developed for tank operators and pilots in WWII. ![]()
