A TEST FOR SPEECH DISCRIMINATION COMPOSED OF CNC MONOSYLLABIC WORDS (N. U. AUDITORY TEST NO. 4)
Abstract
The . U. Auditory Test No. 4 is composed of two lists of 50 CNC monosyllabic words each that conform to the phonemic balance advocated by Lehiste and Peterson. The lists were given twice to three different groups of 16 subjects -- those with normal hearing, those with conductive losses, and those with sensorineural losses. During each test, six presentation levels of ascending intensities were used, the total range being from -4 db to +40 db sensation level. The three types of subjects evidenced articulation functions of the same shape, but the functions for sensorineurals were of gentler slope than for the other two groups. The discrimination scores for list I were slightly higher than for list II. During the retest, the discrimination scores improved slightly. Scores between lists as well as those from test to retest showed relatively high positive correlation. Therefore, the N. U. Auditory Test No. 4 seems to be a valuable tool for the measurement of phonemic discrimination.
