Descriere

Continuing the well-established legacy of the first edition, Industrial Noise Control, Second Edition examines the fundamental principles of noise and vibration control, maintaining the concise format and clarity of presentation that made its predecessor so popular. The authors illustrate solutions to real problems, identify and characterize major sources of industrial noise, and provide systematic design and engineering approaches to control. They supply useful acoustical performance charts, case histories, and tables of materials and supplies. Along with computer-aided calculations and digital instrumentation, the book shows how to plan for compliance with OSHA, DEP and EPA standards.
