| ABSTRACT |
|
According to the international regulations for the standards, the reference sound pressure level (RSPL) for speech audiometry (SA)
is based on the reference speech recognition threshold level (RSRTL). The RSRTL for Korean speech audiometry is not established
yet. Thus, the purpose of this study was to obtain basic data for calculating the RSRTL using Korean speech sounds. Subjects consisted
of 42 adults with normal hearing sensitivity. Puretone thresholds (PTs) were obtained in 2 dB steps at each octave band. Korean
70 bisyllabic words were used to measure speech recognition thresholds (SRTs). The SRT was defined as the level at 50% of
correct responses based on the logistic regression analysis for the results of the psychometric function test. The test was performed
from -6 dB HL up to the level at or above 95% of correct responses in 2 dB steps. Results showed that the mean SRT was 26.59 dB
SPL with the standard deviation of 4.25 dB, which was 6.59 dB greater than the RSRTL of English speech sounds. These results
suggest that the RSRTL be recalculated for Korean speech audiometry for each type of headphone. |
