Human interaural time difference thresholds for sine tones: the high-frequency limit.
The smallest detectable interaural time difference (ITD) for sine tones was measured for four human listeners to determine the dependence on tone frequency. At low frequencies, 250-700 Hz, threshold ITDs were approximately inversely proportional to tone frequency. At mid-frequencies, 700-1000 Hz, threshold ITDs were smallest. At high frequencies, above 1000 Hz, thresholds increased faster than ...
متن کاملFrequency discrimination of short- versus long-duration tones by normal and hearing-impaired listeners.
This investigation explored the effects of stimulus level on the frequency discrimination of long- and short-duration pure tones by 5 subjects with normal hearing and 7 with sensorineural hearing impairment. Frequency difference limens (DLs) were obtained as a function of signal intensity for 5-ms and 300-ms tones at 500, 1000, and 2000 Hz. The performance of most of the hearing-impaired subjec...
متن کاملFrequency difference limens at high frequencies for normal-hearing and hearing-impaired subjects
The smallest detectable change in frequency of a pure tone (the difference limen for frequency, DLF, expressed as ∆f/f) may depend on two mechanisms: a place mechanism based on the filtering within the cochlea [1] and a temporal mechanism based on the patterns of phase locking in the auditory nerve to the “temporal fine structure” (TFS) evoked by the tone [2]. The precision of phase locking wea...
متن کاملVibrotactile Presentation of Musical Notes to the Glabrous Skin for Adults with Normal Hearing or a Hearing Impairment: Thresholds, Dynamic Range and High-Frequency Perception
Presentation of music as vibration to the skin has the potential to facilitate interaction between musicians with hearing impairments and other musicians during group performance. Vibrotactile thresholds have been determined to assess the potential for vibrotactile presentation of music to the glabrous skin of the fingertip, forefoot and heel. No significant differences were found between the t...
متن کاملDistribution characteristics of normal pure-tone thresholds.
OBJECTIVE This study examined the statistical properties of normal air-conduction thresholds obtained with automated and manual audiometry to test the hypothesis that thresholds are normally distributed and to examine the distributions for evidence of bias in manual testing. DESIGN Four databases were mined for normal thresholds. One contained audiograms obtained with an automated method. The...
