What varies is the degree of impairment, but not its spectral slope. So in essence the main finding is that hearing impairment is essentially modelled by a low pass filter curve?

Do you mean, the hearing impairment curve tends to start at a specific band, so what you need is to find the band at which the attenuation starts and compensate the attenuation curve that affects the rest of the spectrum? Since as you said, that impairment slopes tend to be similar among individuals. _______________________________________________ Lisp Hug - the mailing list for LispWorks users [email protected] http://www.lispworks.com/support/lisp-hug.html
