Power series for the reverberation time [PDF]
The Journal of the Acoustical Society of America, 1979 A power series is derived for 1/T, the reciprocal of the geometrical-acoustics reverberation time of an enclosure. The first term is Sabine's expression and the second term provides a correction to the Sabine value in many practical cases where his value is a good, but not quite good enough, estimate of T. The Eyring formula and other expressions which

Revision of Sabine's reverberation theory by following a different approach to Eyring's theory [PDF]
arXiv, 2023 The room acoustic theory was established based on Sabine's reverberation theory. However, in Sabine's theory, the reverberation time does not reach zero, even if the absolute absorption condition is satisfied. This is a contradiction of Sabine's theory, and Eyring revised the reverberation theory to resolve this contradiction.

Reverberation suppression algorithm for LS beamforming based on Wiener post-filter
Dianzi Jishu Yingyong, 2018 Reverberation causes speech signal time and frequency to blur, and speech is difficult to understand when serious. In order to improve the speech quality, this paper presents a least squares beamforming reverberation suppression algorithm with Wiener ...

Model-based optimal action selection for Dyna-Q reverberation suppression cognitive sonar
EURASIP Journal on Advances in Signal Processing, 2023 The Doppler shift of low-speed targets is frequently disturbed by the reverberation Doppler spread clutter under the shallow sea. The clutter is generated by underwater scatterers, which increases the difficulty of Doppler estimation.

Reverberation time, absorption, and impedance [PDF]
The Journal of the Acoustical Society of America, 1977 A rigorous theoretical model is derived and used to calculate reverberation time of a room in terms of impedance of absorption materials on the wall and geometrical factors associated with such materials and the room. In addition, the reverberation time also depends upon the initial state of the pressure field before decay begins as well as on the ...

Changes of Voice Production in Artificial Acoustic Environments
Frontiers in Built Environment, 2021 The physical production of speech level dynamic range is directly affected by the physiological features of the speaker such as vocal tract size and lung capacity; however, the regulation of these production systems is affected by the perception of the ...

On the equation for reverberation time in acoustics
The Journal of the Acoustical Society of America, 1990 A new derivation for the reverberation time equation is here proposed. From the accurate analysis of a model describing the acoustics of enclosed spaces in terms of a feedback system, a surprisingly easy and deep insight of the complex phenomenon of reverberation is readily obtained without any loss of formal rigor.

Understanding and measuring mechanical signals in the tumor stroma
FEBS Open Bio, EarlyView.This review discusses cancer‐associated fibroblast subtypes and their functions, particularly in relation to extracellular matrix production, as well as the development of 3D models to study tumor stroma mechanics in vitro. Several quantitative techniques to measure tissue mechanical properties are also described, to emphasize the diagnostic and ...
