Summary

The Science of Soundis widely recognized as the leading textbook in the field. It provides an excellent introduction to acoustics for readers without college physics or a strong background in mathematics. In the Third Edition, Richard Moore and Paul Wheeler join Tom Rossing in updatingThe Science of Soundto include a wide range of important technological developments in the field of acoustics. New exercises and review questions have been added to the end of each chapter to help readers study the material.For college instructors and students.

Author Biography

Thomas D. Rossing completed his B.A. at Luther College in 1950, his M.S. and Ph.D. at Iowa State University in 1954. His dissertation was in the field of molecular physics. After graduating, he went into industrial research, and from there, he went to teaching. Currently, he is a professor at Northern Illinois University.

Professor Rossing has published more than 200 papers and ten books. He is a Fellow of the Acoustical Society of America and of the American Association for the Advancement of Science. He has held about a dozen research positions other than at his home institution—in national laboratories, in research universities, and in several other countries. The Acoustical Society of America awarded him the Silver Medal in Musical Acoustics.
