[.ca] Fundamentals of Physical Acoustics (ISBN 0471319791)

Physical Acoustics-Dr. Blackstock:
Dr. Blackstock is one of the most lucid technical writers I have encoutered in my (long) career as a phd candidate at UT-Austin Acoustics. If you are trying to understand physical acoustics there is no better book. Kinsler and Frey is weak in comparison. From this book, one can easily step up to Morse's classic Vibration and Sound, or even Theoretical Acoustics with out a flinch. This book is definetely a must have on your personal library.

Excellent text and reference:
I find this book clear and concise. This is the reference I use most often at work when I want insight into the physics behind a noise or vibration problem.
