Effects of illumination on auditory threshold

Physiology & Behavior, 1978
Abstract Auditory thresholds of four squirrel monkeys were examined with a 4 kHz tone in light and dark ambient sensory conditions. The results revealed that auditory sensitivity is higher in the light than in the dark.

Measurement of Auditory Thresholds

The Journal of the Acoustical Society of America, 1965
Two systems of measuring auditory masking thresholds by statistical psychophysical techniques are developed. The first is a succession of free-choice tests with a different level of presentation fixed for each test. In the second, the presentation level is automatically adjusted and maintained at a level close to threshold.

AUDITORY THRESHOLDS AND THE EFEECT OF REDUCED AUDITORY FEEDBACK ON STUTTERING

Acta Psychiatrica Scandinavica, 1975
The effects of reduced auditory feedback were investigated using an accurately calibrated binaudal pure tone producer on 27 stuttering children and 68 non‐stuttering controls.A comparison was made of both auditory hearing and discomfort thresholds in the two groups; the hearing thresholds did not differ between the groups.

Guidelines for Auditory Threshold Measurement for Significant Threshold Shift

Otology & Neurotology, 2016
The purpose of this article is to provide guidelines for determining a Significant Noise-Induced Threshold Shift in clinical trials involving human populations. The article reviews recommendations for the standards to be referenced for human subjects, equipment, test environment, and personnel.

Auditory Motion Perception Threshold

2007 IEEE International Workshop on Haptic, Audio and Visual Environments and Games, 2007
Despite the fact that we are capable of localizing dynamic sound sources, the mechanisms responsible for this are not completely understood since the majority of sound localization research has focused on static environments where the sound source and listener are both stationary. Although various auditory cues can provide motion information, intensity

Diurnal Variability of Auditory Threshold

Acta Oto-Laryngologica, 1964
The absolute threshold for hearing was measured at 7 a.m., noon, 5 p.m., and midnight for 4 days on 6 listeners. No diurnal periodicity appeared, indicating that time of day per se does not constitute a significant source of variance in studies using absolute sensitivity as the dependent variable.

Auditory threshold reduction on alcohol ingestion

Psychopharmacology, 2001
Auditory threshold (AT) measurement method has become the standard behavioral procedure for describing auditory sensitivity. Therefore, the AT measurement method is applicable to evaluation of auditory function. However, only a few studies have been performed to clarify the alteration of audibility under the influence of alcohol on normal humans by ...

The Auditory Threshold for Short-Duration Pulses

The Journal of the Acoustical Society of America, 1971
Data on the variation in quiet threshold with stimulus duration for tone pulses have been used to examine the validity of an integration model of the ear's behavior. It is found that the ear responds to short-duration tone pulses in approximately the manner expected of a single time constant integrator, but that there is a significant frequency effect.

Behavioural estimates of auditory thresholds in hens

British Poultry Science, 1984
Six hens were trained in a trial-by-trial auditory discrimination in which trials were signalled by the lighting of two key lights. Correct responses (left-key pecks when a tone was presented and right-key pecks when it was not) produced intermittent deliveries of food.
