SOUND INTENSITY DISTRIBUTION AND ACOUSTIC POWER OUTPUT OF A SOUND SOURCE IN REVERBERATION CHAMBER

The sound power measurements using sound intensity measuring indicated that the emission of sound source varied in different acoustic environments,the low frequency output of a sound source in reverberation chamber is Lower than that in anechoic room.The direct sound from a source was measured by mesuring the sound intensity in a reverberation chamber.There are some phenomena showing the differences between sound pressure and intensity both in anechoic room and reverberation chamber.
