Japanese company uses cartilage conduction for smartphones to let you hear who’s talking in noisy environments

Rohm Co Ltd, an electronic components maker based in Japan, hopes to change the way we hear people when talking on a mobile phone.

The company has developed a new technology that’s based on “cartilage conduction.” According to Nikkei, this lets you clearly hear someone during a call just by softly touching the phone to your ear. Unlike other bone conduction technologies, cartilage conduction transmits sounds “while blocking external noise.”

Reportedly, Rohm made a chip using this technology, which includes a power supply circuit, a voice processing circuit, and an amplifier. The company intends to use the new product in smartphones first, and wants to promote it to handset makers as a solution for clear conversations in noisy environments.

There already is a prototype iPhone case which uses cartilage conduction (pictured above). The case will be demoed by Rohm from May 10 to May 12 in Japan. It remains to be seen if we’ll be able to enjoy this new technology only by buying an external case or not (some major handset maker might want to include it in its phones by default – assuming that’s possible).

    Either a weird angle, or she has pretty husky hands for an asian woman.

    I would definitely be interested in something like this. I don’t have a documented hearing loss, but I have a lot of trouble hearing people over cell phones. This could also be a useful technology for hearing-impaired people.
