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

Noise 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 ...

AGN Black Hole Masses and Bolometric Luminosities [PDF]

, 2002
Black hole mass, along with mass accretion rate, is a fundamental property of active galactic nuclei. Black hole mass sets an approximate upper limit to AGN energetics via the Eddington limit. We collect and compare all AGN black hole mass estimates from

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

IEEE 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.

The effect of simulated room acoustic parameters on the intelligibility and perceived reverberation of monosyllabic words and sentences.

Journal of the Acoustical Society of America, 2020
Individual acoustic parameters of reverberation have the potential to affect both the intelligibility of speech and the degree of perceived reverberation.

On reverberation mapping lag uncertainties [PDF]

Monthly notices of the Royal Astronomical Society, 2019
We broadly explore the effects of systematic errors on reverberation mapping lag uncertainty estimates from javelin and the interpolated cross-correlation function (ICCF) method.

Black hole scaling relations of active and quiescent galaxies: Addressing selection effects and constraining virial factors [PDF]

, 2019
Local samples of quiescent galaxies with dynamically measured black hole masses (Mbh) may suffer from an angular resolution-related selection effect, which could bias the observed scaling relations between Mbh and host galaxy properties away from the ...

Hierarchical Reverberation Mapping

, 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 ...

Process system engineering in biodiesel production: a review [PDF]

, 2013
Biodiesel is fast becoming a popular alternative to fossil fuels, as it is natural, renewable and has low toxic emissions. Strategies that have been adopted to ensure continued growth of the biodiesel industry are policy development, reduction of ...

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

Noise 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 ...

Fast processing models effects of reflections on binaural unmasking

Acta Acustica, 2023
Sound reflections and late reverberation alter energetic and binaural cues of a target source, thereby affecting its detection in noise. Two experiments investigated detection of harmonic complex tones, centered around 500 Hz, in noise, in a virtual room
