@article{Barman_Gambino_Ramakrishnan_Swallow_1993, title={Reverberation time?}, volume={21}, url={https://jcaa.caa-aca.ca/index.php/jcaa/article/view/783}, abstractNote={Reverberation time (RT<sub>60</sub>) defines the rate of decay of sound energy in a room which in turn is directly related to the overall sound absorption in the room. RT<sub>60</sub> is the transient response (the statistical time domain analysis) of the room which is assumed to be convertible to the steady state decay (the statistical frequency response) of sound in the room with distance. The concept is simple and suitable as a descriptor for room acoustics. The detailed evaluation and measurement of RT<sub>60</sub> however is full of tricks and traps. The problems associated with the evaluation of RT<sub>60</sub> are described first. The difficulties associated with the field measurement of RT<sub>60</sub> are highlighted and the methods usually applied to overcome these are also discussed. Several methods and instrumentation systems for reverberation time measurements are compared and a cost effective procedure is presented}, number={3}, journal={Canadian Acoustics}, author={Barman, M. and Gambino, A. and Ramakrishnan, R. and Swallow, J.C.}, year={1993}, month={Sep.}, pages={79–80} }
