Cochlear nonlinearities

There are 1098 papers searching for "cochlear nonlinearites" ... this isn't a vague, unsupported concept. Read for yourself...

 

I am confident that Adam did not mean that the notion of non-linearity in the auditory system itself is vague or unproven. I think that many of us, Adam included, know very well that there are, very obviously, a number of non-linear mechanisms at play, both mechanically and neurophysiologically.

 

It is just that to put all of these mechanisms together in a bucket, then pointing to that bucket as a clear source of the audibility of ultrasonics, that this is a bit vague.

 

Example: it you press an ultrasonic exciter to your skull (have fun), your will hear something. Does this demonstrate ultrasonic audibility (or rather detectability)? Yes, in a way. Does this rely on intermodulation? Yes, most likely. Is this relevant for audio reproduction in the context we are interested in? No, probably not remotely.

Thats bone conduction. Bone conduction might indeed be relevant for audio reproduction. 

 

So you listen with speakers pressed hard to your skull?

 

Oh, those interested might want to research what is actually being heard with bone-injected ultrasonics.

Is this proven, or your assumption.?

 

That is what I read in one or more reports, many years ago. So no assumption.
