I wonder what the effect of earwax buildup is on this. Without actually knowing anything about OAE, I'd imagine earwax delta could cause greater change in OAE than switching between people with similar ears.
This sounds cool, so hopefully someone can explain why I'm wrong.
You're not wrong. I am less than enthused about this, since I enjoy above-average hearing (and have leveraged this professionally for the last decade as a sound tech). I already have to put up with enough noise pollution: this is about as attractive to me as laser-based iris scanning would be.
There are a number of problems that must be
dealt with, he says. In subjects that have been
drinking alcohol, for example, emissions are
deadened. And different drugs alter the amplitude
of OAEs, as do ear infections or wax build-up.
