Scope
This standard applies to the acoustic characteristics of noise-absorbing pools, including the free-field area of the noise-absorbing pools, the sound pressure reflection factor of the pool interface, and the determination of the pool's background noise. It can also be used as a basis for evaluating the acoustic characteristics of noise-absorbing pools.
