Disclosing the Radio Loudness Distribution Dichotomy in Quasars: An Unbiased Monte Carlo Approach Applied to the SDSS-FIRST Quasar Sample [PDF]

open access: yesApJ, 759, 30 (2012), 2012
We investigate the dichotomy in the radio loudness distribution of quasars by modelling their radio emission and various selection effects using a Monte Carlo approach. The existence of two physically distinct quasar populations, the radio-loud and radio-

Voice quality in affect cueing: does loudness matter?

open access: yesFrontiers in Psychology, 2013
In emotional speech research, it has been suggested that loudness, along with other prosodic features, may be an important cue in communicating high activation affects.

Representation of Instantaneous and Short-Term Loudness in the Human Cortex

open access: yesFrontiers in Neuroscience, 2016
Acoustic signals pass through numerous transforms in the auditory system before perceptual attributes such as loudness and pitch are derived. However, relatively little is known as to exactly when these transformations happen, and where, cortically or ...

The jet power, radio loudness and black hole mass in radio loud AGNs [PDF]

open access: yesAstrophys.J.637:669-681,2006, 2005
The jet formation is thought to be closely connected with the mass of central supermassive black hole in Active Galactic Nuclei. The radio luminosity commonly used in investigating this issue is merely an indirect measure of the energy transported ...

Latencies of conditioned vocal responses to hearing test tones in killer whales (Orcinus orca). [PDF]

open access: yesFront Behav Neurosci
IntroductionPerceived loudness is challenging to study in non-human animals. However, reaction time to an acoustic stimulus is a useful behavioral proxy for the assessment of perceived loudness.

Inter-comparison of Radio-Loudness Criteria for Type 1 AGNs in the XMM-COSMOS Survey [PDF]

open access: yesarXiv, 2014
Limited studies have been performed on the radio-loud fraction in X-ray selected type 1 AGN samples. The consistency between various radio-loudness definitions also needs to be checked.

Spectral and binaural loudness summation of equally loud narrowband signals in single-sided-deafness and bilateral cochlear implant users

open access: yesFrontiers in Neuroscience, 2022
Recent studies on loudness perception of binaural broadband signals in hearing impaired listeners found large individual differences, suggesting the use of such signals in hearing aid fitting.

Continuous Magnitude Production of Loudness

open access: yesFrontiers in Psychology, 2021
Continuous magnitude estimation and continuous cross-modality matching with line length can efficiently track the momentary loudness of time-varying sounds in behavioural experiments.

Real-time loudness normalisation with combined cochlear implant and hearing aid stimulation. [PDF]

open access: yesPLoS ONE, 2018
People who use a cochlear implant together with a contralateral hearing aid-so-called bimodal listeners-have poor localisation abilities and sounds are often not balanced in loudness across ears.

Zwicker’s Loudness model as a robust calculation method for assessment of adequacy of airborne sound insulation descriptors for partition walls in dwelling houses

open access: yesActa Acustica, 2023
The development and validation of single number quantities that are meant to serve for straightforward assessment and comparison of airborne sound insulation properties of partition walls are typically challenged by the necessity to perform large numbers
