HIGH-SCHOOL GYM #3

POINT-SOURCE SYSTEM ON CEILING GIRDERS

DISCUSSION

Gymnasium Acoustics

Designing a successful sound system for a school gymnasium is a major challenge. Most, if not all, surfaces are hard and

the typical gym has little or no absorption material to quiet the reverberation. This makes it difficult to design a system

with good voice intelligibility. Also, students commonly want the system to be loud and musical for their sporting events

and “pep rallies”. Although it’s easy to design a loud system, the gymnasium acoustics make it a challenge to achieve the

“musical” goal.

One way to help meet these challenges is to specify absorption material to improve gymnasium acoustics. Absorption

material can be sprayed onto the ceiling and girders and absorption panels can be installed on the walls high enough to be

out of the way of basketballs or volleyballs.

General System Design Concepts

There are two keys to improving intelligibility and getting good musical sound quality in a gymnasium. First, aim the loud-

speakers at the listeners and, as much as possible, keep the sound away from the walls, floor and ceiling. Community

R-Series loudspeakers can help in this goal because they provide excellent pattern control. Second, to the extent possible,

keep the loudspeakers near the listeners. This improves the direct/reverberant ratio which improves intelligibility. Note

Colors show sound level variation in audience

areas. Other areas will also receive sound (not

shown).
