I'm afraid the above may be confusing non linearity with sensitivity
variations.

The ear does have powerful response mechanisms that adjust the sensitivity
of the sensors to adapt to changes in sound level. However this *isn't* the
same thing as 'non linearity' in the way that term is usually applied, so
need not cause 'distortion' in the usual sense of the term. And the
processing the brain carries out takes these mechanisms into account.
Hearing isn't a simple mechanical process.

You cannot separate the brain from the ear so the whole argument is a bit
academic is it not? The reason you can hear differences is also due to the
brain as a matter of fact.

** Absolute ******** !!!

Human ears are extremely LINEAR !!!

Detecting 0.1% harmonic distortion ( 1 part in a *million* as a power
level ) on a sine wave would not be possible otherwise.


This is why you hear things four times as loud as only twice as loud.


** Rediculous false conclusion.

How loud sounds seem is function of the brain.

Using in ear phones is terribly inaccurate as the fit and acoustic coupling
can change with facial movements and is pretty uncomfortable as well.
The effect of the ear on over the ear phones can very much depend on the
characteristics of the cavity produced.

The big snag with binaural is that in a real sound field, your brain
commands small head movements and thus can hear the differences as the
position changes, with phones the brain cannot move the listening position
unless you have some very odd phones.

I was thinking about doing some dummy head recording and the effect on
frequency response
of using an electret capsule in a model of an ear, compared to just
placing it on the surface of a head-sized sphere.

Any thoughts before I start moulding body parts in plaster?

Years ago when dummy head recording was popular I attended a demonstration
where all sorts of techniques had been used - including a real skull. And
to be perfectly honest the standard two omnis spaced apart the same sort
of distance as ears and separated by a disc approximating to a cross
sectional of a head worked as well as anything.

If you try and reproduce what the ear does you'll double up on that effect
when listening - as the ear isn't linear.

It does, however, give the most convincing stereo for headphone listening.
Can be very impressive. Unlike listening to conventional stereo on
headphones.

Dummy head recording is very old news.

It can only be reasonably be played on headphones.

Do some homework, first. Google gives 100,000 hits
for "dummy head recording".

But not much on dummy head recording using a modeled ear
cavity.

And that makes perfect sense, because the person listening to the recording
listens through a *real* ear cavity.

If you want to go a little beyond a glib put-down,

Seems like it is very much on-target.

Google has interesting stuff on "ear acoustics" such as:

Umm, you just told the guy to go google. Like I just did.
