Re: Outer ear transfer function measured with headphones.
I don't know of a specific reference for the actual transfer
function. It seems that a headphone impulse response is a function of the
listener, the headphones, and the position of the headphones. By position
I mean that if the headphones are taken off and reinstalled in apparently
the same position that the response will change, I found this from
experience and from Kulkarni's work.
I calibrated headphones on an acoustic head for my research. To
get at the impulse response I used a brief swept sine input, measured the
output and then determined the impulse response through a least squares
time domain solution, I believe Kulkarni used a frequency domain solution.
Hope this helps,
