Swimming pools and gymnasiums
Nothing more motivating during a workout than good background music. Likewise, when relaxing in a swimming pool, background music adds to the atmosphere. Yet playing high quality sound in environments such as these is not a trivial task. The reflective surface of a pool has acoustic properties worse than smooth concrete. When constructing a sound system for applications such as these, careful design is needed.
Pools and gymnasiums are notorious for their highly reverberant acoustic environment. The RT60 reveberation time measurement module (featured on all SMxx devices) can be used to measure the reverberation time reliable, for comparison to architectural design specifications and regulations. The STIPA modules featured on the SM30 and SM90 are used to evaluate the intelligibility of sound systems - taking the effect of background noise and reverberation into account.
