NEBB SOUND & VIBRATION DESIGN PDF

This 190 page publication is a concise coverage of the basic concepts of sound and vibration as it relates to HVAC systems, and makes available the most current information for acoustical design and measurement, and assessment of vibration levels in HVAC systems. It provides information not found in any other publication, which includes criteria for acceptable indoor and outdoor noise levels and vibration levels, guidelines for design of quiet HVAC systems, vibration design guidelines, and the latest algorithms for acoustical characteristics of duct elements and total HVAC systems. Topics include:

• The Nature of Sound

• Human Response to Sound

• Equipment Sound Levels

• Duct Element Regenerated Sound Power

• Duct Element Sound Attenuation

• Duct Breakout and Breakin

• Sound Transmission in Indoor and Outdoor Spaces

• General Information on the Design of HVAC Systems

• Vibration Analysis

• Plus reference and glossary

In contrast to highly technical intricate texts with theoretical language written for acoustical engineers, the manual stresses the practical aspects of measuring and controlling sound and vibration within buildings. The easy-to-read text is conveniently organized to promote understanding and ready reference.

The manual was developed by the NEBB Sound and Vibration Committee with the assistance of Dr. Douglas D. Reynolds who is widely known as one of the foremost sound and vibration consultants in the nation. The collective knowledge and experience of the developers is reflected in this highly instructive and valuable reference publication.

This state-of-the-art publication replaces a similar manual published by NEBB in 1978 when it pioneered the development of programs in the sound an vibration field applicable to the HVAC contracting industry. As in the case with the earlier publication, the new manual is unique in content and purpose – not merely an update of previous materials.
