Sound Decay Rates in Various Conference Rooms as Measured by the Automatic Decay-Rate Meter

Abstract

The automatic decay-rate meter described by A. J. Presti [J. Acoust. Soc. Am. 40, 1267 (A) (1966)], has been used to examine the sound decay in a number of conference rooms, with special emphasis on those having fast decay rates. Results are compared with determinations from several different types of oscilloscope presentations. Advantages and limitations in the use of the decay-rate meter will be discussed.
