This text provides undergraduate students with an understanding of the science of sound. Simple mathematics, graphics, and qualitative descriptions are demonstrated to explain wave concepts, spectrograms, intensity, and decibels. Concepts are applied to the physics of speech and hearing.
The graphical approach is supplemented by animations available on an associated Web site containing a complete tutorial with questions that the student can answer. Hints and textual references are given if the wrong answer is chosen and a complete explanation of the question is provided.
Each chapter concludes with “Exercises.”
