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

open access: yesBuildings, 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.

Cascaded-Filter-Based Reverberation Suppression Method of Short-Pulse Continuous Wave for Active Sonar

open access: yesRemote Sensing
Reverberation is the main background interference in active sonar and seriously interferes with the extraction of the target echo. Active sonar systems can use short-pulse continuous wave (CW) signals to reduce the reverberation intensity.

Spring Reverberation: A Physical Perspective [PDF]

open access: yes, 2009
Spring-based artificial reverberation was one of the earliest attempts at compact replication of room-like reverberation for studio use. The popularity and unique sound of this effect have given it a status and desirability apart from its original use ...

AGN Reverberation Mapping

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

Predicting theater chair absorption from reverberation chamber measurements - comment [PDF]

open access: yes, 1993
The relationship between the measured acoustic absorption coefficient of an array of theater chairs and the ratio of the perimeter length to plan area of the array is considered.

Reverberation Modeling for Source-Filter-based Neural Vocoder [PDF]

open access: yesarXiv, 2020
This paper presents a reverberation module for source-filter-based neural vocoders that improves the performance of reverberant effect modeling. This module uses the output waveform of neural vocoders as an input and produces a reverberant waveform by convolving the input with a room impulse response (RIR).

Scene-Aware Audio for 360\textdegree{} Videos [PDF]

open access: yes, 2018
Although 360\textdegree{} cameras ease the capture of panoramic footage, it remains challenging to add realistic 360\textdegree{} audio that blends into the captured scene and is synchronized with the camera motion. We present a method for adding scene-aware spatial audio to 360\textdegree{} videos in typical indoor scenes, using only a conventional ...

A signal enhancement method based on the reverberation statistical information

open access: yesEURASIP 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 ...

Revision of Sabine's reverberation theory by following a different approach to Eyring's theory [PDF]

open access: yesarXiv, 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.

Study on Doppler characteristics of underwater bistatic reverberation [PDF]

open access: yesMATEC Web of Conferences, 2019
Active sonar has two typical types of geometry configuration respectively named monostatic and bistatic like a radar system. In the monostatic scenario, co-located underwater transducers transmit and receive sound energy, while in a bistatic situation ...
