Intensity discrimination in normal-hearing and hearing-impaired listeners.
Weber fractions (delta I/I) for gated 500-ms tones at 0.3, 0.5, 1, 2, and 3 kHz, and at levels of the standard ranging from absolute threshold to 97 dB SPL, were measured in quiet and in high-pass noise in five listeners with cochlear hearing loss and in three normal-hearing listeners. In regions of hearing loss, the Weber fractions at a given SPL were sometimes normal. When the Weber fractions...
متن کاملSample discrimination of frequency by hearing-impaired and normal-hearing listeners.
In a multiple observation, sample discrimination experiment normal-hearing (NH) and hearing-impaired (HI) listeners heard two multitone complexes each consisting of six simultaneous tones with nominal frequencies spaced evenly on an ERB(N) logarithmic scale between 257 and 6930 Hz. On every trial, the frequency of each tone was sampled from a normal distribution centered near its nominal freque...
متن کاملSpectral-peak selection in spectral-shape discrimination by normal-hearing and hearing-impaired listeners.
Spectral-shape discrimination thresholds were measured in the presence and absence of noise to determine whether normal-hearing and hearing-impaired listeners rely primarily on spectral peaks in the excitation pattern when discriminating between stimuli with different spectral shapes. Standard stimuli were the sum of 2, 4, 6, 8, 10, 20, or 30 equal-amplitude tones with frequencies fixed between...
متن کاملPitch perception and harmonic resolvability in normal-hearing and hearing-impaired listeners
Listeners with sensorineural hearing loss are often impaired in their ability to perceive the pitch associated with the fundamental frequency (FO) of complex harmonic sounds. Four studies investigated the relationship between FO discrimination performance and the ability to resolve individual harmonic frequencies of a complex, testing the hypotheses (1) that the accurate FO discrimination perfo...
متن کاملBinaural pitch perception in normal-hearing and hearing-impaired listeners.
The effects of hearing impairment on the perception of binaural-pitch stimuli were investigated. Several experiments were performed with normal-hearing and hearing-impaired listeners, including detection and discrimination of binaural pitch, and melody recognition using different types of binaural pitches. For the normal-hearing listeners, all types of binaural pitches could be perceived immedi...
