Reconciling Statistical Models with Practical Experience of Reverberation Chambers [PDF]

open access: yes, 2009
Presented are novel theoretical probability density functions (PDF) for the magnitude and phase of electromagnetic fields inside reverberation chambers (RC) operating in a dasiagood-but-imperfect regime.

Research on reverberation characteristics analysis and suppression methods for active continuous detection [PDF]

open access: yesMATEC Web of Conferences, 2019
Compared with the traditional active detection with monopulse periodic emission mode, active continuous detection has the advantages of large emission duty ratio and continuous acquisition of process information.

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

open access: yesTrends 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.

Two-Microphone Dereverberation for Automatic Speech Recognition of Polish

open access: yesArchives of Acoustics, 2014
Reverberation is a common problem for many speech technologies, such as automatic speech recognition (ASR) systems. This paper investigates the novel combination of precedence, binaural and statistical independence cues for enhancing reverberant speech ...

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

open access: yesSensors, 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

Blind Estimation of Speech Transmission Index and Room Acoustic Parameters by Using Extended Model of Room Impulse Response Derived From Speech Signals

open access: yesIEEE Access, 2023
The speech transmission index (STI) and room acoustic parameters (RAPs) are essential metrics for assessing speech quality and predicting listening difficulty in a sound field.

Classroom acoustics and hearing ability as determinants for perceived social climate and intentions to stay at work

open access: yesNoise and Health, 2013
Background noise and room acoustics may impede social interactions by interfering with oral communication and other cognitive processes. Accordingly, recent research in school environments has showed that social relationships with peers and teachers are ...

Linear Frequency Modulated Reverberation Suppression Using Non-Negative Matrix Factorization Methods, Dechirping Transformation and Modulo Operation

open access: yesIEEE Access, 2020
In this study, we propose a reverberation suppression algorithm for linear frequency-modulated (LFM) pulse sonar systems using a non-negative matrix factorization (NMF) method.

The effect of room acoustics on the sleep quality of healthy sleepers

open access: yesNoise and Health, 2016
Introduction: Noise is one of the factors that can seriously disturb sleep, and sound volume is an important factor in this context. One strategy involves avoiding exposure to sounds in the night, while entail the minimization of background noise in a ...
