This thesis studied the relationship between preference judgments and discrimination scores obtained using flat and selective amplification. Sixteen subjects with sloping sensorineural hearing losses listened to tapes of PB words and sentences, which had been recorded through flat and selective response hearing aids. Preference judgments and discrimination scores were obtained for each subject.The results of this study indicate that individuals with sloping sensorineural hearing losses do understand speech best with selective amplification. The results also indicate that there is no significant difference between preference judgments for flat or selective amplification. However, the correlation between the preference judgments and the type of amplification best for understanding speech is not very high.
