HearingImpaired Elderly Listeners
The Modified Rhyme Test (MRT), recorded using natural speech and two forms of synthetic speech, DECtalk and Votrax, was used to measure both open-set and closed-set speechrecognition performance. Performance of hearing-impaired elderly listeners was compared to two groups of young normal-hearing adults, one listening in quiet, and the other listening in a background of spectrally shaped noise d...
متن کاملSusceptibility to intraspeech spread of masking in listeners with sensorineural hearing loss.
Previous research with speechlike signals has suggested that upward spread of masking from the first formant (F 1) may interfere with the identification of place of articulation information signaled by changes in the upper formants. This suggestion was tested by presenting two-formant stop consonant--vowel syllables varying along a/ba--/da/--/ga/ continuum to hearing-impaired listeners grouped ...
متن کاملForward masking among infant and adult listeners.
Psychophysical forward-masked thresholds were estimated for 3- and 6-month-old infants and for adults. Listeners detected a repeated 1000-Hz probe, with 16-ms rise time, no steady-state duration, and 16-ms fall time. Unmasked thresholds were determined for one group of listeners who were trained to respond when they heard the probe but not at other times. In the masking conditions, each tone bu...
متن کاملPure-tone octave masking in listeners with sensorineural hearing loss.
Pure-tone octave masking was investigated in 14 listeners with sensorineural hearing loss to examine the hypothesis that the sensorineural ear introduces abnormal harmonic distortion. Thresholds for a test signal at f2, masked by a masking signal at fl, (where fz = 2fl ) were obtained as a function of the level of the fl masker for four different ft frequencies (250, 500, 1000, and 2000 Hz) and...
متن کاملPure-tone octave masking in normal-hearing listeners.
Octave masking was investigated at four different frequencies (250, 500, 1000, and 2000 Hz) as a function of intensity of the masker and phase of the test signal. Slopes of phase-locked octave masking were found to increase with masking signal frequency, from 0.80 dB/dB at 250 Hz to 3.0 dB/dB at 2000 Hz. The monaural octave-masking phase effect was considerably larger for masking signals at low...
