The Effect of Altitude on Absolute Hearing Threshold Levels
Proceedings of the Human Factors Society Annual Meeting, 1982 The present study investigates the effect of hypobaric environments on absolute hearing thresholds for pure tones at octave frequencies between 250 Hz and 8 kHz. Absolute hearing thresholds were obtained for ten subjects at ambient pressure (732 mmHg) and at an altitude of 6500 feet (582 mmHg), relative to the laboratory. Subjects were decompressed in

Journal of Comparative Psychology, 1987 Operant conditioning and a psychophysical tracking procedure were used to measure auditory thresholds for pure tones in quiet and in noise for seven species of small birds--the budgerigar, canary, cockatiel, European starling, song sparrow, swamp sparrow, and the zebra finch. Audibility curves are roughly similar among the seven birds, with the maximum

Influence of a flash light on the absolute threshold of hearing
TENCON 2007 - 2007 IEEE Region 10 Conference, 2007 In this study, to investigate an influence of a visual stimulus presentation on auditory sensitivity, the absolute threshold of hearing was measured under conditions with and without a flash light. In the experiment, pure tones at a frequency of 500 Hz and a duration of 0.5 s were used as the test sound for the measurement of the threshold.

Increased loudness effect at the absolute threshold of hearing
The Journal of the Acoustical Society of America, 2006 This study investigated the effects of a previous sound on loudness at the absolute threshold of hearing. Change of the absolute threshold of hearing was measured when a pure tone preceded the test tone in the measurement of the threshold. The previous sound at 60 dB SPL was presented first in one ear, followed by the presentation of the test sound in ...

Auditory enhancement at the absolute threshold of hearing and its relationship to the Zwicker tone
Hearing Research, 1996 Auditory enhancement describes an improvement in the detection of a tonal signal in a broad-band masker with a spectral gap at the signal frequency if the signal is delayed in its onset relative to the masker. This auditory enhancement may be based on an increase of the effective signal level instead of a decline in the effective masker level. In order

Absolute Thresholds of Human Hearing
American Industrial Hygiene Association Journal, 1967 Abstract Data obtained from high school students indicate that distributions of hearing thresholds determined by puretone audiometry are log-normal. A graphically simplified mathematical method for determining the loci of absolute thresholds of human hearing is presented.

A Time Reversal-Based Acoustic Indoor Localization System at the Absolute Threshold of Hearing
IEEE Sensors Journal, 2015 We present in this paper an acoustic indoor location system that allows a simultaneous localization of sources with different location precisions. This is achieved by the use of the time reversal technique and the code-division multiple-access operation. The system was evaluated in terms of accuracy, precision, and location delay.

Zhurnal vysshei nervnoi deiatelnosti imeni I P Pavlova, 1991 Thresholds of field L auditory evoked potentials EP were studied in 1.5-9-day-old nestlings of pied flycatcher in response to pure tone signals of different frequencies. According to the tendencies of age dynamics of auditory EP thresholds (2-9 days of life) all hearing range was divided into three separate channels: low-frequency (0.3-1.0 kHz ...
