Dear list,

I am unable to get books from Zwicker, Terhardt and other relevant books
about psychoacoustics. So I can not check one thing:
Frequency spreading used in ITU-R BS.1387 is based on Terhardt:

24+230/fc+0.2*L   db/Bark

Is this spreading based on assumption that exact bark scale is used, or is
it based on assumption that bark scale aproximation by Terhardt is used?

Please help.
