Performance of noise-induced hearing-impaired listeners on time-compressed consonant-nucleus-consonant monosyllables

The effects of time compression on the intelligibility of consonant-nucleus-consonant (CNC) monosyllables was investigated by presenting six conditions of a time-compressed versions of the Northwestern University Auditory Test no. 6; at four sensation levels, to nine subjects with noise-induced sensorineural hearing impairments. Results indicated that intelligibility gradually decreased as the ratio of time compression increased, with a dramatic breakdown at the highest ratio of time compression. A typical roll-over phenomenon was also found. Results are related to data on normal listeners.
