There's certainly no shortage of communications products that promise to muffle ambient noise, but a new earbud microphone from Japan is taking an interesting approach: It picks up speech from the ear, not from the mouth. We're not kidding.
That's the explanation given by Nikkei Net Interactive about the "InCore" microphone from start-up Nap Enterprise. The company claims that the technology allows mobile phone conversations "in even very noisy settings like concert halls and construction sites," according to Textually.org, reducing external noise by 30 decibels.
It's just another example of the human skull's evolution as a piece of audio equipment.
