Cortical Characterization of Reverberation Time in Reverberant Speech
2020 42nd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2020Reverberation 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.

Reverberation time measuring methods [PDF]
The 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 ...

Online Blind Reverberation Time Estimation Using CRNNs
Interspeech, 2020The reverberation time, T 60 , is an important acoustic parameter in speech and acoustic signal processing. Often, the T 60 is unknown and blind estimation from a single-channel measurement is required.

Blind estimation of reverberation time
The Journal of the Acoustical Society of America, 2003The 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

Blind Reverberation Time Estimation Using a Convolutional Neural Network
International Workshop on Acoustic Signal Enhancement, 2018The reverberation time of an acoustic environment is a useful parameter for applications including source localisation, speech recognition and mixed reality. However, estimating the reverberation time blindly and on the fly remains a challenge.

A method for extending reverberation time of Dattorro's reverberator
2015 12th International Conference on Fuzzy Systems and Knowledge Discovery (FSKD), 2015Based 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, 2001Time 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 ...

Predicting reverberation times in a simulated classroom
The Journal of the Acoustical Society of America, 2000By varying the sound-absorption treatments in a simulated classroom, experimental results were compared with analytical and computer predictions of reverberation time. Analytical predictions were made with different absorption exponents, which are the result of different weighting procedures involving room surface areas and the sound-absorption ...
