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 would occur in an ideal free sound field. The evaluation of this performance is based on the procedures outlined in ISO 26101.
