Listeners were required to detect increments of intensity or frequency in trains of pure tone bursts under different conditions of attention. The data were analysed taking into account contralateral events when more than one stimulus train was present. Marked changes in d' and β were found and the changes were positively correlated.

Children’s pure-tone detection
The Journal of the Acoustical Society of America, 1980A three-alternative, forced-choice adaptive procedure, with suitable reinforcement, is appropriate for testing auditory sensitivity in young children. Data obtained using this rigidly specified test protocol support previous findings of reduced auditory sensitivity in young children.

Eight cats were trained to localize the source of tonal signals, presented in a free field. Tones of six different frequencies, in octave steps from 250 Hz to 8 kHz, were used. The angle at which an animal's performance was 75% correct was defined as the threshold for minimal detectable angle.

Fatigue effects of a pure tone and pure tones
The Journal of the Acoustical Society of America, 1989Subjects with normal hearing were exposed to moderate intensity of a pure tone and pure tones. Exposure frequency consisted of: a single tone, 1500 Hz; two tones, 1500 and 2000 Hz; and three tones, 1500, 2000, and 3000 Hz. Fatigue effect measurements were made by automatic audiometry immediately after exposure. The greatest fatigue at frequencies 1/2–1

The influence of one pure tone on the threshold of another was investigated. In contrast to previous experiments, masking in the present experiment was studied by determining the level of the masker necessary to mask a signal as a function of the frequency of the masker. The level and frequency of the signal served as parameters.

Computerized Pure-Tone Audiometric Procedures
Journal of Speech and Hearing Research, 1973The purpose of this study was to develop a computer program and the necessary interfacing systems which would enable a PDP/8-I digital computer to (1) control all aspects of administering pure-tone air- and bone-conduction stimuli; (2) recognize the need for masking based on unmasked auditory thresholds, determine the appropriate level of masking, and ...

The results of a test are no better than the competency of the person performing the test. Perfect equipment in the hands of someone untrained, disinterested, or unimaginatively following printed instructions will not produce consistently accurate, worth-while test results.

Pure tone audiometry in children
International Journal of Pediatric Otorhinolaryngology, 2005Our purpose was to evaluate performance of the children on pure tone audiometry (PTA), and role of age, concentration level (CL) and otitis media with effusion (OME) in testing process.This study was prospectively performed on 100 consecutive children referred for PTA between 24 and 120 months of age. After the audiologists' decision on test technique,

Experiments were initiated to determine the frequency most closely associated with a continuous atonal tinnitus reported by a listener with a sloping sensorineural hearing loss in his left ear. The procedure was modeled after that used to obtain a psychophysical tuning curve.

The pure-tone power levels for several types of axial flow fans of less than 12-in. diameter have been determined under different loads and mounting conditions. The method described by Maling and Nordby [Paper J65 in Proceedings of the Fifth International Congress on Acoustics, 1965, Liège, D. E. Commins, Ed.
