Hierarchical Reverberation Mapping [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2013
Reverberation mapping (RM) is an important technique in studies of active galactic nuclei (AGN). The key idea of RM is to measure the time lag $\tau$ between variations in the continuum emission from the accretion disc and subsequent response of the ...

AGN Reverberation Mapping [PDF]

open access: yes, 2015
Reverberation mapping is now a well-established technique for investigating spatially-unresolved structures in the nuclei of distant galaxies with actively-accreting supermassive black holes. Structural parameters for the broad emission-line region, with

On the Quality of Reverberation [PDF]

open access: bronzeThe Journal of the Acoustical Society of America, 1967
In observations and measurements on the acoustical properties of a number of rooms varying greatly in size, shape and decoration, features bearing on the quality of reverberation are noted. In addition to accepted requirements for reverberation times as a function of frequency, some additional factors seem desirable.

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

open access: yesBioengineering
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 Suppression Method for Active Sonar Systems Using Non-Negative Matrix Factorization With Pre-Trained Frequency Basis Matrix

open access: yesIEEE Access, 2021
In active sonar systems, detection always suffers from reverberation interference from multiple scatterers in oceanic environments; therefore, numerous studies have been conducted on reverberation suppression.
