paulears Posted October 27, 2018 Share Posted October 27, 2018 I've been reading about the US Military's new ATAC comms system where the transducer is clipped to the wearers back teeth! Uses bone conduction to create the auditory path through the jawbone. The idea is that the radio system uses near-field magnetic induction technology, so people can remove their clothing and re-dress without having to remove and re-attach comms kit. Leaves the ears open, so situational awareness can be maintained. Handy for replacing the earplug devices that rob you of locational ability. Solution to noisy stages maybe. I find it weird that you clip things to your teeth to talk? Press-to-talk becomes bite-to-talk? Link to comment Share on other sites More sharing options...

paulears Posted October 27, 2018 Author Share Posted October 27, 2018 Both - I suppose it vibrates to send the sound to the ear via the jaw bone, and then can hear what the mouth produces? Don't know any more details but weird, all the same. Link to comment Share on other sites More sharing options...

paulears Posted October 28, 2018 Author Share Posted October 28, 2018 Ha! When I was a teacher in college, none of the music mob had heard of those - they'd not been re-issued then, so I built one. A bit OTT, but I had a spare sealed small HI-FI type speaker 6" woofer laying around so I screwed a sheet of MDF to the front of it, drilled a 25mm hole in the front and araldited in a bit of 25mm plastic hose. Connected it to a guitar head, and tried it out - worked fantastically. On about 2 out of 10 on the volume knob. One of the long guitar strap, heavy metal students tried it, and turned the volume up to 10 in the usual spinal tap stye manner that's compulsory. Put the tube in his mouth, and played a power chord - and was spontaneously sick all over his friends avidly watching. Too much volume in your mouth apparently does this. One of those triggers. Sound hits the back of your throat with plenty of wellie, and it's out of your hands. As I'd glued the tube in, there was a bit of a problem.

the kid Posted October 28, 2018 Share Posted October 28, 2018 GF is doing various research in to hearing aids, touching on bone conduction but it's not the major thing. Her supervisor is working on some bone conduction stuff, partly funded someone in silicone valley. I imagine someone trying to do google glass 2.0 As a whole D0me5tic bone conduction anything is pretty crappy, it requires quite a bit of processing and volume to make it understandable. I imagine US army has some more money and brains to work on it. I think I read about bone condution comms a few years back that were impossible to use as there was nothing actally understandable, add in gunfire and it was even worse.

dmxlights Posted October 28, 2018 Share Posted October 28, 2018 I am a bit deaf myself and I do wear a hearing aid and I have done from a young age. The bone conducter hearing aid has been about a long time. I also have done a bit of looking in to it to see how it works. every one has an inner ear and outer ears and it uses the bone to conduct the sound to the inner ear and that how you will hear the sound. There is a hearing aid called the cochlea ear implant which works very simler to the bone conducter hearing aid but its a lot neeter than the bone conducter hearing aid. the cochlea eir implant works for some poeple with a hearing problem. It will not work for me as I have 2 types of hearing loss ( inner ear and outer ear hearing loss) but a good hearing aid in the outer ear works well for me. Now it may not give me my hearing back 100% but there is some sound fequnecies I do not hear but I have leared how to work around them myself.

timsabre Posted October 28, 2018 Share Posted October 28, 2018 Cochlear implant is not like bone conduction. It actually drives electrical signals into the auditory nerve which the brain learns to interpret as sound. Link to comment Share on other sites More sharing options...
bigclive Posted October 28, 2018 Share Posted October 28, 2018 I wonder if the tooth transducer will kill the nerves in the teeth. Link to comment Share on other sites More sharing options...

It actually drives electrical signals into the auditory nerve which the brain learns to interpret as sound. I know that. The point I was trying to make that they are doing away the bone conduction as in hearing aids. I do know someone (an old school friend) who had a bone conduction hearing aid and now he getting the Cochlear implant as he was told it would give more hearing back. I have been chatting to him 3 days ago and he says he got more hearing than he ever did and he also find the Cochlear implant better. Link to comment Share on other sites More sharing options...
MarkPAman Posted October 29, 2018 Share Posted October 29, 2018 It's bad enough if somebody eats crisps with their mic outside their mouth - I really don't want to hear that from inside http://www.blue-room.org.uk/public/style_emoticons/default/blink.gif Link to comment Share on other sites More sharing options...
