New Hearing Aid Uses Your Tooth To Transmit Sound 93

Posted by ScuttleMonkey from the new-blue-tooth dept.
kkleiner writes to share a new device from Sonitus Medical that transmits sound to the inner ear via the teeth and jawbone. Dubbed "SoundBite," the device captures sound using a microphone in the ear and transmits to an in-the-mouth device that in turn sends the sounds through the jaw. "There are other hearing aid devices that utilize bone conduction. Most, however, use a titanium pin drilled into the jaw bone (or skull) to transmit sound to the cochlea. SoundBite seems to be the first non-surgical, non-invasive, easily removable device. While they are likely years from retail production, Sonitus Medical plans on having SoundBite ITMs fitted to each individual's upper back teeth and fabricated fairly quickly (1 to 2 weeks). A complete system is planned to include two ITMs, 1 BTE, and a charger. In the wider world of cochlear implants, SoundBite may only be fit for relatively specialized use. Still, the ability to easily upgrade or replace individual components makes the device competitive. A similar device could be adapted to provide audio for a personalized augmented reality system. Perhaps the Bluetooth headset of the future will involve actual teeth."

      I saw an item the other day that the warnings about listening to loud rock and roll were bogus; our (boomers') hearing is better than geezers who came before us. The reason is that loud rock music isn't nearly as loud as industrial machinery and firearms; our generation was the first to use hearing protection in the factory and shooting range.

      I lost 10% of the hearing in my left ear in the USAF, when I found that out I realized why they had the rule that you always kept the aircraft to the left of the vehicle. It was so you'd only go deaf in one ear.

      Some sounds are too loud even for hearing protection. Try sitting next to an MD3 (or was it a dash sixty? The one with an F-15 engine in it) while you wait for the guy to come out and change it. LOUD!

            Logical? What do you mean? Would it violate some sylogism or Bayesian rule?

            Since the signal is conducted through the teeth, and the amplifier is what drives the teeth, and the teeth are in the mouth, it would not be "logical" to put the amplifier outside the mouth. Nor would it be physical or electrical.

      Slight corrections: Wikipedia says it was some kind of rod hooked to a piano, not a wire to a clavichord. However, he may have done similar things to both instruments and the citation merely mentioned one. Although pianos are louder, the distance between a player's mouth and the sounding area may also be greater, diminishing the volume advantage, but this is only speculation on my part. (The citation source is fee-based.)

    • My understanding is that Beethoven held a ruler (or equivalent) between his teeth and rested it on the piano so he could hear it. And it would most likely have been a piano rather than a clavichord, which even in Beethoven's day was considered an old-fashioned instrument. Cristofori invented the piano in about 1707, and the other keyboard instruments (harpsichord, clavichord, virginal, essentially everything except organ) fell out of favor after the advantages of the piano became obvious.

        I've seen a fair amount of evidence that he used them sometimes. There's some evidence that he enjoyed the control that clavichords allow, such as vibrato, something hard to produce on a piano. True, they were fading in popularity in his time, but did so slowly. It's roughly comparable to acoustic guitars now. They are still used as a kind of personal, intimate instru

      Bone conduction devices have been around for a lot longer than that. They are primarily used for kids that are too young for hearing aids, or for people that can't use amplification aids due to middle ear issues. They have a headband like the old cheap 80's style walkman headphones with the vibrating unit resting on the bony part just behind your ear. What’s new here is that this device sounds like (heheh) it'll be a whole lot more discrete.

    I saw/heard an external bone conduction device with no spill over into the air, at the Lake County, Indiana fair around 1962 give or take a couple years. It was shaped like a small, rectangular pencil sharpener cut in half so that a half-cone was cut out of one side. That hollow was placed on the bridge of the nose. The fidelity was superb for the time. The drawback was, no stereo, hence no or very poor localization. I've watched for the commercial version ever since, but have never seen one.

    • I have the Baha device mentioned in the OP -- the titanium screw in my skull. It works great. It involved surgery, and that makes it expensive. But it also ensures excellent sound conduction. My left ear is good, so this device is mounted behind my right ear. It allows me to hear sounds from the right side.

      These devices are aimed at two categories of people:
      - Inner ear works, middle ear does not: it gets the sound (vibration) to the inner ear
      - Single sided deafness: it gets the sound from the deaf

    Is this such a good idea?
