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.

Effects of Varying Reverberation on Music Perception for Young Normal-Hearing and Old Hearing-Impaired Listeners

Trends in Hearing, 2018
Reverberation enhances music perception and is one of the most important acoustic factors in auditorium design. However, previous research on reverberant music perception has focused on young normal-hearing (YNH) listeners.

Measurement of Absorption Cross Section of a Lossy Object in Reverberation Chamber Without the Need for Calibration [PDF]

, 2016
A reliable and simple procedure is proposed to measure the averaged absorption cross section (ACS) of a lossy object in a reverberation chamber (RC). This procedure is based on the time-domain measurement of the ACS in an RC.

Interaural Coherence Estimation for Speech Processing in Reverberant Environment

Applied Sciences, 2020
Interaural coherence is used to quantify the effects of reverberation on speech, and previous studies applied the conventional method using all previous time data in the form of an infinite impulse response filter to estimate interaural coherence.

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 ...

Densely Connected Networks with Multiple Features for Classifying Sound Signals with Reverberation

Sensors, 2023
In indoor environments, reverberation can distort the signalseceived by active noise cancelation devices, posing a challenge to sound classification. Therefore, we combined three speech spectral features based on different frequency scales into a densely

A signal enhancement method based on the reverberation statistical information

EURASIP Journal on Advances in Signal Processing, 2022
This paper proposes a reverberation suppression algorithm utilizing fractional lower-order moments based on statistical properties. As fractional lower-order moments can only be applied on symmetric α-stable random variables, the energy redistribution ...
