description A reverberation room comprising walls, ceiling and floor having specific dimensions and spatial relationships used in an automotive testing laboratory to analyze sound for the purposes of measuring transmission loss and sound absorption. The room possesses two transmission loss test windows. One window is placed in the ceiling and one is placed in a side wall. Samples for testing can be mounted horizontally in the ceiling window. A rotating microphone boom is used in combination with the room to sample the sound field in the reverbration room and in reception chambers attached thereto. Three loudspeakers are also positioned in the room to generate the sound field in the reverberation room and indirectly in the reception chambers.
