Speech reception threshold is a base for word discrimination testing, but it also serves as a check for the reliability of pure tone audiogram. In order to investigate the correlation between SRT and PTA these tests were carried out in patients with conductive hearing loss and normal hearing, using Grason-Stadler 1702 Audiometer. The results were as follows; 1) The difference between the scores of SRT and PTA's was 2.4dB with a range of -3.3~8.3dB in conductive hearing loss, and was 1.9dB with a range of -6.7~+5dB normal hearing group. 2) The difference between the scores of SRT and each speech frequency of PTA was 6dB at 500Hz, 3dB at 1,000Hz and 8.8dB at 2,000Hz in conductive hearing loss, and 3dB at 500Hz, 2dB at 1,000Hz and 5dB at 2,000Hz in normal hearing group.
