Reverberation time measurement issues
INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2023 The current ISO attempt to revise ISO 354 has ended in failure because the experts on the working group could not reach agreement in the required time frame. However, several important issues were identified. Some of these issues are discussed in this paper.

Reverberation Time Characteristics of Severence Hall
The Journal of the Acoustical Society of America, 1959Following the changes in the acoustical conditions made in Severance Hall during the summer of 1958 [see R. S. Shankland and E. A. Flynn, J. Acoust. Soc. Am. 31, 866 (1959)] a series of reverberation time measurements were made during the 1958–1959 concert season of the Cleveland Orchestra.

Reverberance of an existing hall in relation to subsequent reverberation time and SPL
The Journal of the Acoustical Society of America, 1998Psychological tests in relation to reverberance of sound fields were conducted in an existing hall which is a medium-sized multipurpose hall with 400 seats. Music and speech as sound sources were radiated from an omnidirectional dodecahedron loudspeaker on the stage.

Optimum Reverberation Time for Auditoriums
The Journal of the Acoustical Society of America, 1930Up to the present, the acoustics of auditoriums has rested on a purely empirical basis. A more satisfactory situation would be reached if we knew a physical quantity which had some definite value for all rooms, regardless of size, which are considered acoustically good.

Reverberation time measuring methods
The Journal of the Acoustical Society of America, 2008In this paper different well-established methods of reverberation time measurement are compared. Furthermore, the results obtained using these methods are compared to the results provided by some additional methods which could serve as an in situ tool if, for any reason, the reverberation time measurements cannot be carried out using the standardized ...

Measurement of reverberation time in the National Bureau of Standards reverberation room
The Journal of the Acoustical Society of America, 1976The spatial variation of the reverberation time in the 1/3-octave bands from 80 to 10 000 Hz was studied as a function of: (1) the surface area of the absorbing material ranging from 0 to 13.4 m2; (2) the orientation and rotational speed (0–10 rpm) of the vanes; (3) loudspeaker placement and type; (4) discrete microphone versus high-speed multiplexed ...

Measurement of Reverberation Time
American Journal of Physics, 1965A simple experiment to measure the reverberation time of a room is described. The relevant theory is outlined, and typical results are given. The experiment is designed for inclusion in a course of practical work for first-year university students in physics.

Reverberation time series generation
2009 International Symposium on Ocean Electronics (SYMPOL 2009), 2009This paper deals with the generation of non-stationary reverberation time series using a reverberation spectrum model. The expected spectra are predicted using a numerical implementation (referred to as the reverberation spectrum model), of a general formulation of Faure, Ol'shevskii, and Middleton as a function of relevant sonar system parameters and ...

Reverberation Time Measurements in Reverberant Spaces
2008The goal of this paper is to examine the reverberation time measurements made in small and large reverberant spaces using different measurement methods, namely, the integrated impulse response measured with pink noise, exponential sweep and MLS and the method of recording the response of the room to an impulsive source, e.g.

‘Reverberation Time’, dreaming and the capacity to dream
The International Journal of Psychoanalysis, 2009In this paper the author suggests that understanding the roots of the subjective sense of time can throw light on the disturbances in psychic time which are found in particular in the more severe pathologies. She introduces the argument that the roots of the development of the sense of time rest on a primitive sense of time she calls 'reverberation ...
