초록
Although auditory training is one of the main elements of aural rehabilitation, its limitations in terms of time andcost give many hearing-impaired adults less opportunity to achieve better speech perception skill. This studydevelops an auditory training program for mobile devices that was then applied to an adult listener suffering frombilaterally moderate-to-severe sensorineural hearing loss to examine its efficacy. The training program had 4 levels(i.e., discrimination, advanced discrimination, identification with a closed-set condition, and identification with anopen-set condition) and each level was planned to be completed in one week. To examine whether the subjectachieved enhanced speech perception, the vowel, consonant, and sentence tests before- and after the training wereevaluated to compare the two training scenarios. After 4 weeks of auditory training using a mobile device, theresults showed that performance in the consonant and sentence tests largely increased except for the vowel test thatproduced 100% correct scores in before- and after training. These results suggest that a moderate amount ofauditory training using a mobile device is effective when it is used to improve the speech perception ofhearing-impaired adults.
