Psychoacoustics for Dummies - with examples?

Does anyone know of good introductory texts or references on psychoacoustics that include audio material?

Just the one - Acoustics and Psychoacoustics 4th ed. - Howard and Angus. UK Amazon link here. If you purchase a new copy, it comes with a CD of examples. Hopefully the secondhand ones (if available) do as well...

And it's quite a useful book.

Thanks Steve.  Judging from the TOC it's just the sort of content I'm looking for, with references at the end of each chapter to keep me busy during the long South Dakota winter!
