抄録

The reliability of the clinical application of the Multiple Auditory Steady-State Response (MASTER) test as a measure of the hearing threshold was evaluated in 35 children with hearing impairment. The thresholds of MASTER were given within two hours. The mean of the time for completing MASTER testing was 57 minutes with a range of 25-115min. In 14 affected ears, the findings of both MASTER and the 80Hz amplitude modulation following response (80Hz AMFR) at a carrier frequency of 1000Hz were examined during sleep. The thresholds of MASTER were compared with behavioral thresholds, which were determined by standard pure-tone audiometry or play audiometry in 13 ears. A significant relationship between MASTER and 80Hz AMFR thresholds was observed, with a Pearson r value of 0.81. MASTER and behavioral hearing thresholds highly correlated at the audiometric test frequencies of 1000Hz, 2000Hz and 4000Hz with the exception of 500Hz. Overall, MASTER can be used as a predictor of the behavioral threshold in children with hearing loss at the frequencies 1000-4000Hz.
