Time reversal acoustics applied to rooms of various reverberation times.
Journal of the Acoustical Society of America, 2018Time Reversal (TR) is a technique that may be used to focus an acoustic signal at a particular point in space. While many variables contribute to the quality of TR focusing of sound in a particular room, the most important have been shown to be the ...

Reverberation time of the Rotunda of Thessaloniki
The Journal of the Acoustical Society of America, 1975The Rotunda of Thessaloniki is a unique 4th century monument of romanesque art, with an octagonal floor plan and a volume of 15 645 n3. Today it is used as a hall for orchestral and choral presentations. The reverberation time of the Rotunda has been measured on three different occasions, and the obtained data, together with the listeners absorption ...

Holographic measurement of reverberation time
Applied Acoustics, 1979Abstract A system employing the radio frequency holographic method for the measurement of the reverberation time of an acoustic chamber is proposed. This system has the advantage of supplying visible information on the diminishing intensity of the acoustic wave.

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.

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.

In ocean environments, reverberation is an inevitable interference for active sonar system. The reverberation has many characteristics quite similar to target echo, thus resulting in high false probability during active sonar detection.

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.
