An Introduction to the Psychology of Hearing, Brian C.J. Moore, 5th edition, 2003
- Best introduction to psychoacoustics (most up-to-date). Recommended as a non-mathematical introduction.
Auditory Perception, Richard M. Warren, Cambridge University Press, 1999
- More of the same, with lots of overlap (get the above instead, imho)
The Intelligent Ear, Reinier Plomp, Lawrence Erlbaum Associates, 2002
- Very modern overall view with lots on speech understanding and some important points on high level research issues. Recommended (annoying postscript/printing errors though)
Introduction to Audiology, 8th ed., F.N. Martin & J.G. Clark, Allyn & Bacon, 2003
- Basic introduction to clinical audiology. Very layman approach. Understandable to most (BTW, only buy this if you're really into audiology, this is a periphery book for psychoacoustics, imho)
Introduction to Digital Audio, 2nd ed., John Watkinson, Focal Press, 2002
- Basic introduction to digital signal processing theory (and some applications). A condensed version of Art of Digital Audio (of sorts)
Digital Audio Technology, 4th ed., Sony, Focal Press, 2001
- Basics of digital audio (really rudimentary level) and more importantly how cd, dvd, sacd and minidisc work. Accurate reference for the CIRC diagram explanations (AFAIK)
Psychophysics - the Fundamentals, 3rd ed., George A. Gescheider, Lawrence Erlbaum Associates, 1997
- Standard text on psychophysics. For me as a reference only. Haven't read it, so no futher comments.
Sensation and Perception, 6th ed., Bruce Goldstein, Wadsworth Publishing, 2001
- Basic perceptual psychology text, covering not only hearing, but vision and chemical senses as well. Many useful basic cognitive models, but I'd only recommend those more interested in cognition and sensory research in overall (the hearing part may be worth reading through though).
Signals and Perception, David Roberts (ed.), Open University, 2002
- Contains IMHO an excellent anatomical/neurological introduction to hearing. Also covers vision, touch, smell/taste, so there's stuff that's probably not of interest to HA members. However, if you can find this at your library, the articles 2-4 are really interesting and I'd recommend them to anyone seriously interested in understanding hearing. Very good illustration/images, imho.
BTW, apparently 'Principles of Digital audio' (Ken C. Pohlman) has errors in the CIRC encoder/decoder explanations. Haven't had time to verify this myself

As for the Zwicker/Fastl, according to my professor it is not completely up-to-date, although a standard reference in the field (esp. for engineers). I have it, but it's been gathering dust, I'm afraid.
