On Black Hole Masses and Radio Loudness in AGN

open access: yes, 2000
The distribution of radio to optical fluxes in AGN is bimodal. The physical origin for this bimodality is not understood. In this Letter I describe observational evidence, based on the Boroson & Green PG quasar sample, that the radio loudness bimodality ...

The intensity JND comes from Poisson neural noise: Implications for image coding [PDF]

open access: yes, 2000
While the problems of image coding and audio coding have frequently been assumed to have similarities, specific sets of relationships have remained vague.

What is Noise Sensitivity?

open access: yesNoise and Health, 2022
Background: Noise sensitivity moderates the association between environmental noise exposure and annoyance and health outcomes. Methods: In normally hearing adults, we measured noise sensitivity in three ways: using the noise sensitivity questionnaire, a

Loudness (annoyance), prediction procedure for steady sounds [PDF]

open access: yes, 1972
Method has been devised to predict loudness level of any steady sound solely from its measured power spectrum level. Method is based on assumption that, with respect to loudness sensation, the human auditory system acts as open-loop transmission system ...

Advanced Rating Method of Airborne Sound Insulation

open access: yesApplied Sciences, 2016
This paper describes an advanced calculation scheme based on the loudness level linked to the specific fluctuation strength yielding a weighted normalized loudness level difference as a single number value.

Merging the Psychophysical Function With Response Times for Auditory Detection of One vs. Two Tones

open access: yesFrontiers in Psychology, 2022
The purpose of this study is to take preliminary steps to unify psychoacoustic techniques with reaction-time methodologies to address the perceptual mechanisms responsible for the detection of one vs. multiple sounds.

Japanese VLBI Network observations of radio-loud narrow-line Seyfert 1 galaxies [PDF]

open access: yes, 2007
We performed phase-reference very long baseline interferometry (VLBI) observations on five radio-loud narrow-line Seyfert 1 galaxies (NLS1s) at 8.4 GHz with the Japanese VLBI Network (JVN).

Mental imagery for musical changes in loudness

open access: yesFrontiers in Psychology, 2012
Musicians imagine music during mental rehearsal, when reading from a score, and while composing. An important characteristic of music is its temporality.

Perception of loudness changes induced by a phononic crystal in specific frequency bands

open access: yesActa Acustica, 2022
To study the influence of classical phononic crystal (PC) structures on the acoustical characteristics of a sound source, a combined acoustics/perceptual analysis is conducted on a PC specially designed to exhibit several spectral and wave vector ...

Somatic tinnitus [PDF]

open access: yes, 2017
Modulation of tinnitus characteristics such as pitch and loudness has been extensively described following movements of the head, neck and limbs, vertical or horizontal eye gaze, pressure on myofascial trigger points, cutaneous stimulation of the hands ...
