| ABSTRACT |
|
It has been well known that the selection of maximum power output in hearing aids fitting is important. In general, it was determined
through the uncomfortable loudness level (UCL) test. The purpose of this study was to measure and compare the UCL and acoustic
reflex threshold (ART) in young normal children and adults for early intervention and aural rehabilitation, including hearing aids
fitting for hearing-impaired children. Pure tone hearing threshold, UCL and ART were measured in 40 ears of children and adults with
normal hearing respectively. In results, UCL was higher than ART by 8.9 dB in children and was similar to ART in adults. And UCL,
dynamic range (DR) and ART of children was higher than that of adults by 12.0 dB and 3.6 dB. In conclusion, we would suggest to
monitor environmental noises properly and thoroughly for children's hearing based on the our results. |
