The Auditory Threshold for Short-Duration Pulses
The Journal of the Acoustical Society of America, 1971Data 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, 1984Six 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.

Auditory Threshold in the Goldfish (Carassius auratus) as a Function of Signal Duration
, 1972Auditory thresholds were determined in the goldfish (Carassius auratus) for sound pulses with duty cycles from 1%–90% of 100‐ and 1000‐msec periods. Thresholds were also determined for pulses from 10 to 500 msec in duration with at least 490 msec between

SLEEP MENTATION AND AUDITORY AWAKENING THRESHOLDS
Psychophysiology, 1970ABSTRACTAuditory awakening thresholds (AATs) were assessed in 53 Ss during all stages of sleep and at various times of night. Sixteen of these Ss met previously devised criteria for an AAT light‐sleep group (LSG) and 16 for an AAT deep‐sleep group (DSG).

Effects of Age on Auditory Awakening Thresholds
Journal of Gerontology, 1984Auditory awakening thresholds ( AATs ) were assessed in sleeping men and women at three age levels (18 to 25, 40 to 48, and 52 to 71 years) with a procedure that employed a 5-sec tone in accordance with the up-and-down method. Although age was less influential than individual differences in predicting AAT levels, there was a significant and substantial

Reliability of auditory threshold determinations using a circumaural-earphone assembly.
Journal of the Acoustical Society of America, 1967In a previous paper, a circumaural earphone that was intended to improve the reliability of auditory threshold measurements was described. This paper is concerned with its evaluation using the results from tests on 100 subjects. The test‐retest variances

Auditory thresholds in monkeys asphyxiated at birth
Experimental Neurology, 1971Abstract Thresholds to pure-tone stimuli were determined in eight normal monkeys and six monkeys that had been asphyxiated at the time of birth, using a two-way avoidance paradigm. Asphyxiated animals had elevated thresholds at each of the frequencies tested, 0.5, 1, 2, 4, and 8 kHz.

Test-retest reliability of auditory threshold and temporary threshold shift.
Scandinavian Audiology, 1983Test-retest reliability of auditory threshold and temporary threshold shift (TTS) at 4 kHz and 8 kHz was examined. Twenty normally hearing subjects were exposed to a 3-min 110 dBSPL white noise on three occasions. Results indicated reduced reliability of

Absolute auditory threshold: testing the absolute
European Journal of Neuroscience, 2017AbstractThe mechanisms underlying the detection of sounds in quiet, one of the simplest tasks for auditory systems, are debated. Several models proposed to explain the threshold for sounds in quiet and its dependence on sound parameters include a minimum sound intensity (‘hard threshold’), below which sound has no effect on the ear.
