Re: Transfer function of middle ear

[alexander lerch <lerch@xxxxxxxxx>]

Hello Vivek,

I'm not familiar with PAQM, but it might be that PAQM uses the
same transfer function of outer and middle ear as PEAQ (ITU-R
BS.1387) does, because PAQM was one of the systems
"integrated" in the PEAQ recommendation.
PEAQ's function is derived from
Terhardt: Calculating virtual pitch, Hearing Research Vol.1,
1979

You can find information about PEAQ's transfer function and
PEAQ itself at:
http://www.itu.int/rec/recommendation.asp?type=folders&lang=e&parent=R-REC-BS.1387

Best regards,
Alexander
