An inner perforated layer of light gauge sheet metal (baffle) The baffle is then filled with sound-absorptive insulation In high velocity systems, or when there is a concern for particulate matter in the air stream, a bagged or mylar-faced insulation is used. Packless sound attenuators do not include sound-absorptive insulation.
It is important to distinguish between genuine infinite-baffle topology and so-called infinite-baffle or IB enclosures which may not meet genuine infinite-baffle criteria. The distinction becomes important when interpreting textbook usage of the term (see Beranek (1954, p. 118) [ 13 ] and Watkinson (2004) [ 14 ] ).
The attenuator is a specialty duct accessory that typically consists of an inner perforated baffle with sound-absorptive insulation. Sound attenuators may take the place of ductwork; conversely, inline attenuators are located close to the blower and have a bellmouth profile to minimize system effects.
