A comparative evaluation of the Maryland NU 6 auditory test

This study was conducted to determine the performance-intensity functions of the Maryland NU 6 Auditory Test (female voice) with normal-hearing and hearing-impaired persons, to examine equivalency of the four lists, and to compare performance scores on this test with those obtained on the CID W-22 Test and the Maryland CNC Test. Three lists were judged to be equivalent, and there was good test-retest reliability. The test made distinctions among individuals with varying degrees of high-frequency hearing loss. Word recognition scores for the Maryland NU 6 and Maryland CNC Tests were remarkably similar, but differed significantly from those obtained on the W-22 Test.
