Reverberation Time in Vehicular Cabins
2018This paper research is focused on the reverberation time produced inside cabins where the influence of windows on wide-band signals is substantial. This kind of scenarios are important for the new generations of wireless communications since high-density scenarios with high-traffic demand are one of the keys environments.

Blind reverberation time estimation by intrinsic modeling of reverberant speech
2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013The reverberation time (RT) is a very important measure that quantifies the acoustic properties of a room and provides information about the quality and intelligibility of speech recorded in that room. Moreover, information about the RT can be used to improve the performance of automatic speech recognition systems and speech dereverberation algorithms.

Reverberation time slope ratio
The Journal of the Acoustical Society of America, 2019T60 Slope Ratio: Symbolically—T60SR6 A proposed standard for condensing six octaves (63 Hz – 2 kHz) of reverberant decay data into a singular-quotient, qualitative score for performance, worship and entertainment facilities. Specifically, a defining metric for scoring and grading the proportional relationship (i.e., ratio) between the longest and ...

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.

The reverberation times of some English cathedrals
Physics Bulletin, 1963Measurements of reverberation times have been made in a number of English cathedrals as part of the research program or in connection with other acoustic investigations. Reverberation time is the one measurement in the field of room acoustics which can be made comparatively easily and which can be related in a limited way to the subjective appreciation

Reverberation Time Formulae Reconsidered
The Journal of the Acoustical Society of America, 1972The widely used reverberation time formula due to Eyring was derived on the assumption of step-wise drops in the energy level of a diffuse sound field. The argument, besides being difficult to follow, was not justified from the statistical notion of a diffuse field.

Automatic Reverberation Time Recorder
IETE Journal of Research, 1956AbstractThe method of measurement of reverberation time by tracing decay curves is tedious though accurate. Occasions frequently arise when the need for a quick determination of reverberation time vs. frequency curve is felt. An equipment constructed in the Research Department, All India Radio, which can plot the reverberation time vs.

Reverberation versus time or reverberation versus range? A definitive relationship.
The Journal of the Acoustical Society of America, 2009Strictly reverberation consists of all the back-scattered contributions from many locations that arrive at one absolute time regardless of their respective travel times. However, for calculation purposes, particularly at long range, it is often more convenient to assume the scatterers to be close together at a single location with corresponding ...

New Method of Measuring Reverberation Time
The Journal of the Acoustical Society of America, 1965A new method of measuring reverberation time is described. The method uses short pulses of acoustic energy, such as pistol shots or tone bursts, to excite the enclosure. An integral over the response of the enclosure yields, in a single measurement, the average of infinitely many decay curves that would be obtained with random noise as the excitation ...
