초록
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.
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.
