The use of California Consonant Test (CCT) in hearing aid evaluations was considered in this study. The CCT was processed through two hearing aids and presented to 14 normal hearing adults according to two procedures. Initially, an adaptive procedure was used to determine the signal-to-noise ratio that would permit 50% intelligibility. Then, a full list of the CCT was presented at this signal-to-noise ratio for validation purposes. Results suggested that hearing aids can be effectively differentiated with considerable time saving when an adaptive procedure is applied to the CCT. Results of the full list presentation demonstrated the adaptive procedure to be sufficiently accurate.
