Abstract

Reverberation rooms are used as test rooms to investigate the level of sound power and to test the space bound hardware including antennas and satellites. These rooms can be used to understand transmission properties of building materials and absorption properties of noise control products. An ideal reverberation rooms need to have adequate volume, suitable shape, small sound absorption, and low background noise level. Two different rooms were used to evaluate the sound level produce by single sinusoidal tones and bands of noise. The reverberation chambers can be used to determine the spatial uniformity of the chamber and the low-frequency cut-off limit of the chamber. It was observed that the spatial uniformity of the chamber sound level can be satisfied for broadband sound levels.
