Increased perception of loudness in autism
Hearing Research, 2004Clinical reports on autism describe abnormal responses to auditory stimuli such as intolerance to sounds. The present study assessed subjective perception of loudness in subjects with autism compared to healthy controls, using two psychoacoustic tests. First, the auditory dynamic range was evaluated at six different tone frequencies. Secondly, loudness

Fine structure of hearing threshold and loudness perception
The Journal of the Acoustical Society of America, 2004Hearing thresholds measured with high-frequency resolution show a quasiperiodic change in level called threshold fine structure (or microstructure). The effect of this fine structure on loudness perception over a range of stimulus levels was investigated in 12 subjects. Three different approaches were used.

Loudness perception of signals of monotonically changing sound pressure
The Journal of the Acoustical Society of America, 1977Listeners were required to judge whether a 500-Hz stimulus, whose SPL was monotonically changing, was increasing or decreasing in loudness over its 2-sec duration. Performance was best when single stimuli were presented in isolation. Providing a second, fixed SPL stimulus for use as a reference generally resulted in poorer performance especially as the

Loudness Perception of the Blind
International Journal of Audiology, 1972Over the years numerous stories have evolved about the perceptual abilities of the blind. This study was an attempt to examine one area of auditory function of blind subjects - that described by equal-loudness contours. The hypothesis under test stated that there is no significant difference between the blind and sighted in thewir perception of ...

The Contour Test of Loudness Perception
Ear and Hearing, 1997This article presents the underlying rationale, normative data, and reliability data for a test of loudness perception (the Contour Test) that was devised for use in clinical hearing aid fitting. The Contour Test yields data describing the sound level required for each of seven categories of loudness ranging from very soft to uncomfortably loud.Two ...

Music Preferences and Perception of Loudness
Perceptual and Motor Skills, 1989again. The second ratings were either the same (70%) or different by only one (28%) in almost all cases, so means of these two ratings were used for analysis. On the second procedure, the 10 selections were played again, and the subjects were asked to adjust the loudness of the music to their preferred level using a volume control knob that varied from

Plasticity of loudness perception
The Journal of the Acoustical Society of America, 2002Evidence from the management of tinnitus and hyperacusis suggests that loudness perception is plastic and adaptable. We have undertaken a study to evaluate this idea. The motivation followed from clinical observations suggesting that the magnitude of perceived loudness and, in turn, the rate of loudness growth can be manipulated either upward or ...

The Perception of Control in Loud Noise
Perception, 1984Perception of control is known to affect performance under stress. Two experiments are reported the object of which was to find out how loud noise during a contingency assessment task influences perceived control. Subjects were required to choose one of two responses, note one of two results, and then provide an overall percentage estimation of the ...

Verifying Loudness Perception After Hearing Aid Fitting
American Journal of Audiology, 2001During the verification phase of a hearing aid fitting, clinicians often want to assess the extent to which loudness perceptions for amplified sounds are similar to those typical of normal hearers. This type of verification calls for a criterion for "normal" loudness perception of sounds presented in a sound field.

Narrative Review of Loudness Perception Measures in Children
Ear & Hearing, 2022Recent surveys of pediatric audiologists have highlighted the need for improved understanding of pediatric loudness perception and their role in the hearing device fitting process. The purpose of this article is to provide a brief overview of methods used to measure loudness perception and summarize the existing literature exploring loudness perception
