Noise Control

The second edition of Noise Control: From Concept to Application, newly expanded and thoroughly updated, now includes 180 graded problems with solutions, plus 100 end-of-chapter problems with solutions available for instructors on the authors website. Working from basic scientific principles, the authors show how an understanding of sound can be applied to real-world settings, working through numerous examples in detail and covering good practice in noise control for both new and existing facilities. It covers the essential topics for industrial noise control: acoustics, noise criteria, hearing-damage risk, noise-assessment measures, measurement instrumentation, sound-source types including the calculation and measurement of their output power, sound propagation outdoors, sound in rooms, sound-absorbing materials, sound transmission through partitions and enclosures, noise barriers, reactive and dissipative muffler-noise reduction and muffler-design considerations such as pressure loss and self-noise generation. Detailed explanations of important concepts make this textbook easy to understand by engineering and science undergraduates, as well as professionals with no background in acoustics.
