Abstract:

Northwestern University Auditory Test No. 6 is composed of four lists of 50 consonant-nucleus-consonant CNC monosyllabic words each. The construction of the test followed the same scheme employed earlier in the development of N. U. Test No. 4, a less extensive version using the same type of material. The four lists of N.U. Test No. 6 were given twice to each of two subject groups--one group with normal hearing and another with sensorineural hypoacousis. During each administration, six ascending presentation levels were used ranging from -4-dB to 40-dB sensation level. The two groups yielded articulation functions highly similar to those obtained with the earlier test N.U. Test No. 4. The new test N.U. Test No. 6 appears to have good interlist equivalence and high test-retest reliability. It thus retains the desirable features of the earlier tool while doubling the inventory of items available for the measurement of phonemic discrimination.
