The purpose of this thesis was to investigate the California Consonant Test by manipulating selected variables to determine whether it would be a reliable and valid alternative to the presently used CID W-22 word lists with the sensorineural hearing loss population. This study also looked at the scores obtained on the two discrimination tests and the scores obtained on the Profile Questionnaire for Rating Communicative Performance. In this way, a closer look was taken to determine how much difficulty hearing impaired individuals were reportedly experiencing in understanding speech as compared to their actual performance on the two discrimination tests.The test population consisted of 16 male and 16 female subjects with bilateral symmetrical, sensorineural hearing losses. The CID W-22 Auditory Test and the California Consonant Test (live voice and recorded presentations) were administered to each subject under aided and unaided conditions. At the end of each testing session, each subject was asked to answer the Profile Questionnaire for Rating Communicative Performance in a Home Environment.Pearson's Product-Moment Correlation Coefficient and t-tests for independent measures were calculated to determine if significant correlations existed.It was concluded from this investigation that the California Consonant Test is a more sensitive indicator of the phoneme difficulties experienced by the individuals with &high frequency sensorineural hearing loss than is the' CID W-22 Auditory Test. Although significant correlations were not obtained between the two discrimination tests and the questionnaire, a question by question analysis indicated that all the individuals had at least some difficulties in all situations proposed in this questionnaire. It would therefore seem that the California Consonant Test is a more accurate indicator of the individual's problems in the communicative situation.
