The Maryland CNC Test: normative studies.
These studies were conducted to determine the performance-intensity functions of the Maryland CNC Test (male voice) with normal-hearing and hearing-impaired persons, to examine the equivalence of the 10 lists, and to determine test-retest reliability. There was a 2.1% increase per decibel in word recognition in the linear portion of the performance-intensity function for normal listeners and a 1.3% increase per decibel for hearing-impaired listeners. 6 lists were judged to be equivalent, and there was good test-retest reliability. Hearing-impaired subjects demonstrated a wide range of scores on the Maryland CNC Test, suggesting that this measure can distinguish among varying degrees of word recognition ability.
