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.

Reverberation time slope ratio

The Journal of the Acoustical Society of America, 2019
T60 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 ...

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 recommendations for noisy industrial workshops

Journal of Occupational and Environmental Hygiene, 2020
Industrial workshops or any other industrial premises where noisy machines are operated should be as acoustically absorbent as possible. On the other hand, acoustic treatments are expensive (especially when correcting existing premises), messy, and not always compatible with the implemented production processes.

Reverberation Time Measurements in Reverberant Spaces

2008
The goal of this paper is to examine the reverberation time measurements made in small and large reverberant spaces using different measurement methods, namely, the integrated impulse response measured with pink noise, exponential sweep and MLS and the method of recording the response of the room to an impulsive source, e.g.

Reverberation Time Formulae Reconsidered

The Journal of the Acoustical Society of America, 1972
The 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.

Time reversal of interface reverberation

The Journal of the Acoustical Society of America, 2004
Bottom reverberation can be used as a probe-source of opportunity to construct a time-reversal focus that scans along a rough interface. We present results from a tank experiment at ultrasonic frequencies in which reverberation from a sandy bottom was collected on a 64-element source/receiver array.

Holographic measurement of reverberation time

Applied Acoustics, 1979
Abstract 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.

Measurement of Reverberation Time

American Journal of Physics, 1965
A simple experiment to measure the reverberation time of a room is described. The relevant theory is outlined, and typical results are given. The experiment is designed for inclusion in a course of practical work for first-year university students in physics.
