OAEs reveal cochlear function through sounds emitted back into the ear canal

Evidence

Otoacoustic emissions—sounds generated by your own hearing system—are a condition everyone’s flesh is to some degree heir to, simply because the hearing apparatus, from ear to brain, works not only as a receptor but as an amplifier. — George Michelsen Foy, Zero Decibels, 329 (#expands, via linked claim)
