Resilient Acoustic Panels For Noisy Sports Halls
Sports halls acoustics can be particularly harsh. Sports halls and gymnasiums spaces are normally oversized, hollow and comprised of durable, yet hard and reflective surfaces. The result is an echo chamber of harsh noise, with reverberation times that can easily reach over 5 seconds. Throw into the mix large crowds, a highly vocal environment and intense sporting activity and you can have a very hostile sound environment. Poor sports hall acoustics can mean that instructors are unable to be heard, personal training sessions can lack privacy, and an unfriendly user environment is created. Additional challenges are posed to school sports halls, which must meet strict BB93 compliance guidelines and should create acoustic comfort for a multitude of uses – assemblies, plays and exams etc.
DesignDesign of Sports halls is usually undertaken with little or no consideration given to the importance of acoustics. These spaces are made to be durable to accommodate a range of sporting activities. The resulting rooms are large and hollow; with hard surfaces that reflect noise sharply.
MaterialsHard, impact resistant materials (concrete, drywall, wood and brick) are commonly used in the construction of sports halls. These materials can only absorb around 5% of sound, meaning that surplus noise is reflected between the floor, ceiling and other hard surfaces before dying off. Testings of sports hall acoustics has found that reverberation time can be as high as 10 seconds.
