“At last, an easy-to-read volume that has a real bent towards sound reproduction pre¬sented at both the technical and practical levels. Plus, each chapter has problem sets… Overall, a highly recommended book, particularly given its attractive price.”

About the Item
Acoustics and Audio Technology, Third Edition, is an introductory text for students of sound and vibration as well as electrical and electronic engineering, civil and mechanical engineering, computer science, signals and systems, and engineering physics. A basic knowledge of basic engineering mathematics and physics is assumed. Problems are included at the end of the chapters and a solutions manual is available to instructors. This classroom-tested book covers the physical background to and mathematical treatment of sound propagation, the properties of human hearing, the generation and radiation of sound as well as noise control, and the technologies used for pickup, recording, and reproduction of sound in various environments, and much more. |
