SMACNA HVAC SOUND MANU
HVAC SOUND AND VIBRATION MANUAL
|Publication Date:||1 December 2004|
This first edition of HVAC Sound and Vibration was developed to provide in−depth, HVAC−specific guidance in the art of sound and vibration measurement and mitigation. In addition to this manual a chapter on the subject is provided in HVAC Systems Duct Design. Also, in HVAC Duct Construction Standards Metal and Flexible commentary and illustrations are provided in Chapter 7 to evaluate the relationships between duct vibration and a number of factors airflow velocity and pressure, metal gage, etc.
As building construction has become lighter and tighter, sound and vibration that previously may have gone unnoticed is more often becoming a nuisance. This creates both a problem and an opportunitya problem because designers and installers must be diligent in using materials and techniques that mitigate the potential for sound and vibration problems and an opportunity for contractors that specialize in resolving occupant complaints related to sound and vibration.
While this manual provides industry−recognized methods and
techniques, not all practices are discussed or illustrated as this
would be impractical. Deviations from included recommendations may
often be permissible, depending upon verification of satisfactory
results under conditions other than those covered in this manual.
Careful examination of the information herein and the expertise of
local contractors will enable designers or facility managers to
select the proper detail for practically any requirement. You can
