Reverberation time measuring methods [PDF]

open access: possibleThe Journal of the Acoustical Society of America, 2008
In 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 ...

Cortical Characterization of Reverberation Time in Reverberant Speech

2020 42nd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2020
Reverberation reduces speech quality, and therefore causes inconveniency to listeners, especially those using assistive hearing devices. To enhance the quality of reverberant speech, a significant step is speech quality assessment, most of which are based on subjective judgements.

Blind estimation of reverberation time

The Journal of the Acoustical Society of America, 2003
The reverberation time (RT) is an important parameter for characterizing the quality of an auditory space. Sounds in reverberant environments are subject to coloration. This affects speech intelligibility and sound localization. Many state-of-the-art audio signal processing algorithms, for example in hearing-aids and telephony, are expected to have the

A method for extending reverberation time of Dattorro's reverberator

2015 12th International Conference on Fuzzy Systems and Knowledge Discovery (FSKD), 2015
Based on the introduction of the digital reverberation algorithm, we use the integrated impulse response method, and the method of compressing and extending the reverberation model impulse response to solve two existing problems of the Dattorro's plate reverberator in the practical application.

Time-reversed reverberation focusing in a waveguide

The Journal of the Acoustical Society of America, 2001
Time reversal mirrors have been demonstrated to focus acoustic energy in the ocean at ranges of tens of kilometers from a probe source [W. A. Kuperman et al., J. Acoust. Soc. Am. 103, 25–40 (1998)]. Time reversal has also been exploited to focus acoustic energy at discrete scatters of unknown location using the eigenvectors of the time reversal ...
