Featuring an exciting new chapter on several aspects of speech acoustics by Raymond D. Kent, PhD!With a new chapter, the classic textbook, Introduction to Sound: Acoustics for the Hearing and Speech Sciences, is back in a fifth edition and continues its aim to teach fundamental concepts of acoustics to students in communication sciences and disorders and related disciplines. Students of speech-language-hearing science must have a thorough understanding of the elements of acoustics before they can successfully embark on more advanced study of both normal and disordered human communication.The text is known for how acoustical concepts have been made understandable for all students, not just those who are already grounded in mathematics and physics. Coverage includes the nature of sound waves, simple harmonic motion, acoustic impedance, scales of measure, logarithms and antilogarithms, sound intensity and pressure, complex waves, resonance and filtering, distortion, sound transmissions, speech acoustics, and room acoustics. Key FeaturesSummaries, Notes, and Practice Problems end each chapter Bolded key terms throughout with end-of-book glossaryAlphabetical listing of selected equationsThe numerous equations are displayed in blue for easier readingNew to the Fifth EditionA new chapter, Basic Principles of Speech Acoustics, written by Raymond D. Kent, PhDA special emphasis on editing the content throughout for increased readability and comprehensionPluralPlus Online Ancillary MaterialsFor instructors: PowerPoint SlidesFor students: Practice Problems, Acoustic Animations

Charles E. Speaks, PhD, is a Distinguished Morse-Alumni Professor Emeritus in the Department of Speech-Language-Hearing Sciences at the University of Minnesota. He received his Bachelor of Science and Master of Arts degrees from Ohio University and his PhD degree from the University of Michigan. He taught an undergraduate/graduate-level course in acoustics at the University of Minnesota for 39 years and developed an undergraduate course on the physics and biology of spoken language. Dr. Speaks was awarded a Distinguished Teacher Award by the College of Liberal Arts in 1977 and a Horace T. Morse-Minnesota Alumni Association Award for Outstanding Contributions to Undergraduate Education in 1997, and he was inducted into the University of Minnesota Academy of Distinguished Teachers in 1999. Dr. Speaks also was awarded the Honors of the American Speech-Language-Hearing Association in 2002.
