This 62,000 cubic foot cafeteria's ceiling and side
walls are conditioned with 1300 linear feet of ASC's SoundPlank
for a total coverage of 915 square feet. The existing RT60 is brought
down from 3.75 seconds (measured) to 1.24 seconds (measured) -well
within the RT60 range recommended for its room type. Scroll down
for an audio before-after clip.
layout of the SoundPlanks provides well balanced room acoustics,
with intelligibility greatly improved and yet a lively sound quality
preserved. As noise builds up, people have to speak louder and louder
to be heard. The "acoustic speed bump" effect of the arrayed
SoundPlanks will slow down this noise buildup problem.
The graph below shows the measured RT60's before
(in blue) and after (in red)
the conditioning process.
