Sound and Noise measure

Whether for performance venues, architectural measurements, or work-place acoustics, reverberation time is a key parameter for characterizing a room. Reverberation time data provides information about the quality of sound as perceived by the audience in a room. A long reverberation time can make speech less intelligible, and music more pleasing. Too short a reverberation time can muffle speech and make a room sound “thin.”  Reverberation time sound level meter Larson Davis 831C-RT with Room Acoustics Firmware 831C-RA offers reverberation time measurement and calculation.
