‘Reverberation Time’, dreaming and the capacity to dream

International Journal of Psychoanalysis, 2009
In 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 ...

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.

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.

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

The Reverberation Time Bridge—An Instrumental Method for Measuring Reverberation Time

The Journal of the Acoustical Society of America, 1930
The analogy between the decay of the electrical energy in a capacitor shunted by a resistor and the decay of sound energy in a room with sound absorbing walls is the basis of this bridge. The sound pressure is converted into a corresponding electrical voltage by a microphone and amplifier.

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 ...

Blind reverberation time estimation by intrinsic modeling of reverberant speech

2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013
The 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 in Vehicular Cabins

2018
This 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.

Predicting reverberation times in a simulated classroom

The Journal of the Acoustical Society of America, 2000
By 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 ...

Reverberation Time Characteristics of Severence Hall

The Journal of the Acoustical Society of America, 1959
Following 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.
