Acoustical Panels on Walls and Ceiling in Multi-Purpose Space
Westfield, NJ YMCA
Both gymnasiums and natatoriums tend to be noisy due
to the activity level and the reflectivity of the interior surfaces. While an
overwhelming noise level might be desirable during a basketball game, it is
hardly useful most other times. Noise levels interfere with instruction and
frequently make it impossible to converse much less address a class when there
are other groups in the space. Speech levels are amplified and, when people
cannot communicate at reasonable voice levels, they shout making the situation
worse.
If the gymnasium also serves as an auditorium, the distortion
level (reverberation time) frequently makes it difficult if not impossible to
understand a speaker, music or announcement.

In order to reduce these levels and reverberation
time absorbent materials need to be introduced into the space. This can be done
by the use of acoustical banners and/or panels. Both must be able to resist
abuse and be efficient absorbers of sound. Reverberation times in excess of 10
seconds are frequently normal for these types of spaces. A correctly configured
array of the properly designed materials can bring the reverberation time down
to less than two seconds with a concurrent reduction in the noise level of 40 -
50% (up to 10dBa). Placement of acoustical panels opposite the stage will
provide for intelligibility during assemblies.
