Six months post-fitting, 68.1% of Korean adults with unilateral HI who had agreed to try a hearing aid continued to use it regularly. The predictors for hearing-aid use six months post-fitting included social and/or work activities and digital signal processing.

Among 735 patients with SSNHL, 94 were included in the IT-S group, 444 in the SST, and 197 in the CT group. Age, gender, interval from disease onset to start of treatment, and initial hearing level were not different among the three groups. Patients who had concomitant medical disorders such as diabetes mellitus, hypertension, or chronic renal failure were more frequently treated with IT-S. No difference in the level of hearing gain or ratio of hearing improvement was observed among the three groups (p = 0.147 and p = 0.067, respectively).

Students with UHL in noisy classrooms require seating ranging from 4.35 m to no further than 6.27 m away from a teacher to obtain a SDS comparable to normal hearing adults and student peers.
