Abstract: The presently accepted method for measurement of the decay of sound in an enclosure calls for decay from “steady state” excitation by bandlimited noise, measured with rms pressure sensing instrumentation. Other methods, such as the rms Pressure Impulse Response scheme used by Knudsen and Delsasso in several studies and Schroeder's Integrated Pressure-Squared procedure, have not found widespread use, even in view of the time savings which can be realized. In this study, the decay of sound in several diverse acoustical environments had been measured by five different signal processing techniques, including the three mentioned above. The results of the measurements are shown and differences and similarities analyzed.
