| ABSTRACT |
|
The present study was to evaluate the differences with procedures, and to investigate test-retest reliability of category loudness
scaling. Ten subjects(20 ears), 19~23 year-old, with normal hearing and no sound tolerance problems were participated in the session
which was held twice, with a week interval. Pure tone of 0.5, 1, 2, 3, 4 kHz were presented by using TDH- 39 headphone and
ascending method in 5 dB steps from threshold. Nine scaling categories from very soft to painfully loud (Hawkins et al., 1987), and
seven categories of loudness ranging from very soft to uncomfortably loud (Cox et al., 1997) were used. The UCL showed lower
10-20 dB but SD was recorded larger than normative data from different country. There were no differences of UCL according to the
pure tone frequencies. The test-retest differences of category loudness scaling were investigated within 5 dB. There were differences
within 10 dB in different procedures of MCL and UCL. These data might be useful in hearing aid fitting and the rehabilitation. |
