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 ...

Optimum Reverberation Time for Auditoriums
The Journal of the Acoustical Society of America, 1930Up to the present, the acoustics of auditoriums has rested on a purely empirical basis. A more satisfactory situation would be reached if we knew a physical quantity which had some definite value for all rooms, regardless of size, which are considered acoustically good.

Reverberation Time Characteristics of Severence Hall
The Journal of the Acoustical Society of America, 1959Following 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.

The necessity of determining the optimum reverberation time in relation to the purpose of the room appears as a problem during the design and modeling of room acoustics. The paper discusses different recommendations for determining the optimum reverberation time, which are analyzed graphically and numerically.

Reverberation time prediction software
Applied Acoustics, 1988Abstract Reverberation time prediction in room acoustics is a subject suitable for the development of a microcomputer software application. Based on two data-bases—one for the actual predictions and one for the building and acoustical materials needed to control the acoustical conditions of a room—such an application, using a conversational ...

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.

Reverberation time slope ratio
The Journal of the Acoustical Society of America, 2019T60 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, 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.

Reverberation time recommendations for noisy industrial workshops
Journal of Occupational and Environmental Hygiene, 2020Industrial 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.
