SLEEP MENTATION AND AUDITORY AWAKENING THRESHOLDS

Psychophysiology, 1970
ABSTRACTAuditory 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).

Auditory Thresholds During Stroboscopic Visual Stimulation

The Journal of the Acoustical Society of America, 1969
Twelve experienced subjects participated in a Békésy-type tracking procedure and obtained their thresholds for a 25- and a 300-msec duration 1-kHz pulsing auditory stimulus in the absence and presence of time-locked stroboscopic visual stimulation. Six subjects obtained their thresholds in quiet, and the remainder tracked threshold in the presence of ...

Auditory Thresholds of the Cat

The Journal of the Acoustical Society of America, 1955
The auditory thresholds of the cat have been obtained by the conditioned response method. Tests were made for frequencies from 62.5 to 60 000 cps. The upper limit of the cat's hearing is in the neighborhood of 60 000 cps. A comparison of threshold curves for cat and man suggests that the cat may be slightly less sensitive than man for frequencies of ...

Hypoxia and auditory thresholds.

Aviation, space, and environmental medicine, 1976
This paper reports the effects of hypoxia on hearing. Pure tone hearing and speech discrimination were tested at ground level and during hypoxic states at simulated altitudes of 4,600 m (15,000 ft) and 6,100 m (20,000 ft) in a high-altitude chamber. Pure tone hearing was not significantly altered during hypoxia produced by this method.

Auditory Threshold Impairment And Everyday Speech Reception

International Journal of Audiology, 1973
The effect of auditory threshold impairment on the reception, in quiet and in noise, of lists of sentences designed to represent everyday speech was investigated in war vetarans, the majority of whom had sensorineural hearing loss. It was found that reception of the sentences by the subjects could be predicted with reasonable accuracy by means of the ...

Effects of Age on Auditory Awakening Thresholds

Journal of Gerontology, 1984
Auditory 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

Detection of Abnormal Auditory Threshold Adaptation (ATA)

Archives of Otolaryngology - Head and Neck Surgery, 1971
Abnormal threshold adaptation (ATA) is known to be an indication of refractory neural disease in the auditory system. Comparison of the Carhart tone-decay test, Bekesy sweep frequency, and fixed-frequency tests, and the Rosenberg and Owens modifications of the Carhart test in the same groups of patients demonstrates that the Carhart test gives more ...

Hearing Threshold Shift during Auditory Magnitude Estimation

Perceptual and Motor Skills, 1992
The purpose of the present experiment was to determine the extent of hearing threshold shift that may occur during an auditory magnitude-estimation task involving stimulus intensities as great as 80 dB sensation level. Also, possible influences of hearing threshold shift on numerical magnitude-estimation responses and magnitude-function slopes were ...

Circadian Variability of Auditory Threshold

The Journal of the Acoustical Society of America, 1963
Recently, Neuberger and Schmid [Archiv Ohren- Nasen- u. Kehlkopfheilk. ver. Z. Hals- Nasen- u. Ohrenheilk. 179, 237-258 (1962)] reported that the auditory threshold shows a circadian (diurnal) variability, being 10–15 dB higher (less sensitive) at midnight than at noon.
