Very Large Baseline Array observations of Mrk 6 : probing the jet-lobe connection [PDF]

, 2014
We present the results of high-resolution VLBI (very long baseline interferometry) observations at 1.6 and 4.9 GHz of the radio-loud Seyfert galaxy, Mrk 6. These observations are able to detect a compact radio core in this galaxy for the first time.

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

Frontiers 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 ...

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

Frontiers in Behavioral Neuroscience
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.

Application of Psychoacoustic Metrics in the Noise Assessment of Geared Drives

World Electric Vehicle Journal
Psychoacoustic metrics offer a valuable complement to traditional noise evaluation methods for gear transmissions, as they account for the human perception of sound quality rather than relying solely on physical measurements.

Effect of sonic boom asymmetry on subjective loudness [PDF]

The NASA Langley Research Center's sonic boom apparatus was used in an experimental study to quantify subjective loudness response to a wide range of asymmetrical N-wave sonic boom signatures.

On the origin of radio-loudness in AGNs and its relationship with the properties of the central supermassive black hole

, 2011
We investigate the relationship between the mass of central supermassive black holes and the radio loudness of active galactic nuclei. We use the most recent calibrations to derive virial black hole masses for samples of radio loud QSOs for which ...

One's own and similar voices are more attractive than other voices

Australian Journal of Psychology, 2019
Objective The aim of the present study was to explore whether people consider their own voice to be more attractive than others and whether the self‐enhancement bias of one's own voice could be generalised to other variants of self‐voice.

Toward an ecological conception of timbre [PDF]

, 2002
This paper is part of a series in which we had worked in the last 6 months, and, specifically, intend to investigate the notion of timbre through the ecological perspective proposed by James Gibson in his Theory of Direct Perception.

Reducing Audible Spectral Discontinuities [PDF]

, 2001
In this paper, a common problem in diphone synthesis is discussed, viz., the occurrence of audible discontinuities at diphone boundaries. Informal observations show that spectral mismatch is most likely the cause of this phenomenon.We first set out to ...
