Anechoic test room
- ISO 3745 Acoustics -- Determination of sound power levels andsound energy levels of noise sources using sound pressure -- Precision methods for anechoic rooms and hemi-anechoic rooms
- ISO 3741 Acoustics -- Determination of sound power levels andsound energy levels of noise sources using sound pressure -- Precision methods for reverberation test rooms
The Anechoic testroom includes the Anechoic Room (With or Without theAir Conditioning) and the Semi Anechoic Room (With or Without the AirConditioning). It is the important Test Room for the sound test of the AirConditioner, the Electrical Product, and the Electronics Product.The test room can be used to provide the Sonic Field, the Semi SonicField and the Diffusion Field. It uses the Sonic Pressure Method toprovide the Testing Sound and therefore to determine the DB grade ofthe test object.
