Impact of Temperature and Relative Humidity on Reverberation Time in a Reverberation Room

Buildings, 2022
Changes in acoustic parameters measured in a room may depend on the location and orientation of the sound source and microphones or on the reverberation conditions of the room.

Investigation of the Appropriate Reverberation Time in Learning Spaces for Elderly People Using Speech Intelligibility Tests [PDF]

Buildings, 2022
The Republic of Korea is currently an aging society, and it will enter an ultra-aging society in 2025. This study aimed to investigate the undesignated appropriate reverberation time of learning spaces for elderly people in Korea.

Velocity-resolved Reverberation Mapping of Five Bright Seyfert 1 Galaxies [PDF]

Astrophysical Journal, 2018
We present the first results from a reverberation-mapping campaign undertaken during the first half of 2012, with additional data on one active galactic nucleus (AGN) (NGC 3227) from a 2014 campaign.

Sensitivity of Acoustic Voice Quality Measures in Simulated Reverberation Conditions [PDF]

Bioengineering
Room reverberation can affect oral/aural communication and is especially critical in computer analysis of voice. High levels of reverberation can distort voice recordings, impacting the accuracy of quantifying voice production quality and vocal health ...

Reverberation times and reverberation levels

Archives of Acoustics, 2015
Reverberation times and reverberation levels are the statistical parameters of the stochastical sound field in a room. Their theoretically derived and practically measured properties are discussed.

Reverberation suppression using non-negative matrix factorization to detect low-Doppler target with continuous wave active sonar

EURASIP Journal on Advances in Signal Processing, 2019
In active sonar systems, the detection of echo from targets can deteriorate due to reverberation. Detection becomes more difficult if targets have low-Doppler frequency and are located near the reverberation band, especially in an environment with low ...

Improved snapshot-deficient active target localization using the knowledge-aided covariance of reverberation [PDF]

JASA Express Letters, 2023
Underwater reverberation often hinders the effectiveness of adaptive methods in active target localization with snapshot-deficient conditions. To overcome this challenge, a knowledge-aided reverberation covariance-based approach is proposed to maintain ...

The NICER “Reverberation Machine”: A Systematic Study of Time Lags in Black Hole X-Ray Binaries [PDF]

Astrophysical Journal, 2022
We perform the first systematic search of all NICER archival observations of black hole (and candidate) low-mass X-ray binaries for signatures of reverberation.
