Pure-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 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 کاملCochlear compression in listeners with moderate sensorineural hearing loss.
Psychophysical estimates of basilar membrane (BM) responses suggest that normal-hearing (NH) listeners exhibit constant compression for tones at the characteristic frequency (CF) across the CF range from 250 to 8000 Hz. The frequency region over which compression occurs is broadest for low CFs. This study investigates the extent that these results differ for three hearing-impaired (HI) listener...
متن کاملComplex-Tone Pitch Discrimination in Listeners With Sensorineural Hearing Loss
Physiological studies have shown that noise-induced sensorineural hearing loss (SNHL) enhances the amplitude of envelope coding in auditory-nerve fibers. As pitch coding of unresolved complex tones is assumed to rely on temporal envelope coding mechanisms, this study investigated pitch-discrimination performance in listeners with SNHL. Pitch-discrimination thresholds were obtained for 14 normal...
متن کاملPerception of roughness by listeners with sensorineural hearing loss.
The perception of auditory roughness presumably results from imperfect spectral or temporal resolution. Sensorineural hearing loss, by affecting spectral resolution, may therefore alter roughness perception. In this study, normal-hearing and hearing-impaired listeners estimated the roughness of amplitude-modulated tones varying in carrier frequency, modulation rate, and modulation depth. Their ...
