## Fundamentals of AcousticsA clear treatment of the fundamental principles underlying the generation, transmission, & reception of acoustic waves & their application to numerous fields. Analyzes the various types of vibration of solid bodies & the propagation of sound waves through fluid media. The third edition features discussions of antiresonance concert hall acoustics, detection theory, canonical equations, normal mode propagation in the ocean, & environmental acoustics. Material on absorption, hearing, architectural acoustics, & underwater sound has been expanded & updated. |
