摘要:
A sound decay curve in a reverberation room was photographed by means of an oscillograph. Computing the rate of decay from this film the total absorption in the room can be computed. The average results obtained by this method may be in close agreement with those obtained by the ear using the usual reverberation method, but the method as at present developed requires a prohibitive amount of time and labor.
