American National Standard Acoustics – Determination of sound power levels and sound energy levels of noise sources using sound pressure – Precision methods for anechoic rooms and hemi-anechoic rooms
Abstract
The performance of an anechoic or hemi-anechoic room is tested by comparing the spatial decrease of sound pressure emitted from a test sound source with the decrease of sound pressure that...
