Re: Headphone equalization

Hi Larry

I could suggest chapter 8.3 in Bech & Zacharov "Perceptual audio evaluation. Theory, method and application" ( http://eu.wiley.com/WileyCDA/WileyTitle/productCd-0470869232.html ) - there you will find an explanation of the various standard procedures as well as references to all the international standards on calibration of headphones.

Re: Headphone equalization

Quick solution:

In the telecommunications speech band, you could pull a pair of
Sennheiser HD600's off the shelf and do no equalization and have
reasonable confidence that they are +/- a few dB.

Not so quick solution:

There are much more involved calibration schemes we use for playback
of binaural recordings, but they involve an artificial head and
modeling the transfer function in MATLAB with linear phase FIR
