Measures of signal processing in persons with sensorineural hearing loss below 6 kHz.
Estimates of threshold, wide- and narrow-band noise masking, frequency and amplitude modulation detection, gap detection, and rate discrimination were obtained from 10 subjects with near-normal hearing at frequencies above 6 kHz, but severe-to-profound hearing losses at lower frequencies. The same measures were obtained from 10 young control subjects with normal hearing sensitivity for all frequencies up to 16 kHz. The hearing-impaired subjects were able to process sounds in the region of near-normal hearing sensitivity as well as the unimpaired control subjects. Performance in the low-frequency, impaired region depended on the lowest frequency of near-normal hearing sensitivity.
