INDOOR ICE RINK #2

SEMI-DISTRIBUTED SYSTEM ON ROOF BEAMS

DISCUSSION

Ice Rink Acoustics

Designing a successful sound system for an indoor ice rink is a major challenge. Most, if not all, surfaces are hard and the

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

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

Although it’s easy to design a loud system, the facility acoustics make it difficult to achieve the “musical” goal.

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

can be sprayed onto the ceiling and girders and absorption panels can be installed on the walls.

General System Design Concepts

There are two keys to improving intelligibility and getting good musical sound quality in a space like this. First, aim the

loudspeakers 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.
