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 Features
- Summaries, Notes, and Practice Problems end each chapter
- Bolded key terms throughout with end-of-book glossary
- Alphabetical listing of selected equations
- The numerous equations are displayed in blue for easier reading
New to the Fifth Edition
- A new chapter, Basic Principles of Speech Acoustics, written by Raymond D. Kent, PhD
- A special emphasis on editing the content throughout for increased readability and comprehension
