HDAcoustic accepts
source sound power levels in the standard octave bands and
based on geometries and construction of the housing plenum,
estimates sound power levels at openings in the plenum or air
handling unit, as well as estimating radiated sound power
levels.
While standard
absorption and TL coefficients are pre-loaded in the program,
HDAcoustic is extremely flexible, allowing you to input your
own custom coefficients providing acoustical estimates for any
plenum or AHU construction.
Multiple sound sources and multiple
openings are fully supported by HDAcoustic.
