The effects of time-compressed monosyllabic CNCs on the auditory discrimination performance of 96 young adults with normal hearing were studied. Five conditions of time compression, 30% through 70% in 10% steps, plus a 0% control condition were presented at four sensation levels (8, 16, 24, and 32 dB). Ear presentation and list version were counterbalanced with these factors. Results indicated that intelligibility was inversely related to time-compression ratio and directly related to sensation level. Ear and list effects were minimal.
