Fundamentals of physical acoustics

Author: David T Blackstock
Publisher: New York : Wiley, ©2000.
Edition/Format:   Print book : English
Summary:
"Easy to read and understand, Fundamentals of Physical Acoustics fills a long-standing need for an acoustics text that challenges but does not overpower graduate students in engineering and physics. Mathematical results and physical explanations go hand in hand, and a unique feature of the book is the balance it strikes between time-domain and frequency-domain presentations." "Fundamentals of Physical Acoustics is  Read more...
