Otoacoustic emissions (OTE) constitute a well known phenomenon, first observed and described, if I am not mistaken, by David Kemp in the 70's. The news these days, at least for me, is that OTE is the latest addition to the biometric techniques chest.
The ear produces a unique sound signature, which can identify you in a way similar to your fingerprints.
Forget the musical ear, the thinking ear, the absolute ear. The ear produces sound! An accusing sound. We belong to the deaf culture. We are endowed with the guilty ear.
Don't you dare play by ear, it may be held against you.
