Acoustics of indoor sports halls and gymnasia

摘要

Unoccupied and occupied noise and acoustic surveys in typical indoor sports halls and gymnasia have confirmed that the majority of these spaces have very long reverberation times, high occupied noise levels and poor speech intelligibility. These are likely to be contributory factors towards the incidence of voice problems among sports teachers and reported difficulties of students hearing in such spaces. The long reverberation times in sports halls could be reduced by the introduction of acoustically absorbent material which would improve listening, hearing, understanding and speaking conditions in these spaces.
