Currently in the otologic field, there are various method of audiometric examinations such as pure and speech and impedance. A few studies has been done in these fields in Korea. The purpose of this paper is to establish norms and the relationship of norms of various audiometric tests, so I have performed the tests in 100 male medical students and 50 female medical and nursing students in healthy physical condition and the following results were obtained : 1) The mean of the PTA (Pure Tone Average) was 4dB on the male right, 3dB on the male left, 4dB on the female right, 2dB on the female left and the mean of the SRT(Speech Reception Threshold) was 4dB, 3dB, 3dB, 3dB, respectively. 2) The mean of the MCL (Most Comfortable Loudness) was 45dB on the male right, 46dB on the male left, 45dB on the female right, 44dB on the female left. 3) The mean of the UCL(Uncomfortable Loudness) was 102dB on the male right, 102dB on the male left, 103dB on the female right, 102dB on the female left. We had trouble in estimating the UCL in about half the cases as we could not estimate the UCL with our conventional audiometer. 4) All cases showed over 90% in the PB Score and 100% was the most common level. 5) SISI(Short Increment Sensitivity Index) test was done at 1,000 and 4,000 Hz. The most common level was 0% and above 80% was not seen. 6) TD(Tone Decay) test was done at 2,000 and 4,000 Hz. The most common level was 0dB and above 20dB was not seen. 7) Tympanogram was A type with one exception which was B type on the male left. 8) The mean of the tympanogram peak level was 22.8mmH₂O on the male right, 23.9mmH₂O on the male left, 20.7mmH₂O on the female right, 23.6mmH₂O on the female left and the mean of static compliance was 0.6 cc on all sides. 9) The mean of the contralateral stapedial reflex threshold at 500, 1,000, 2,000, 4,000Hz was 89dB, 85dB, 88dB, 92dB on the male right, 89dB, 85dB, 89dB, 91dB on the male left, 90dB, 86dB, 89dB, 93dB the female right, 89dB, 85dB, 89dB, 91dB on the female left. Depending on the tested frequencies, the stapedial reflex was not generated in 2.25% on the male, 1.75% on the female. 10) The mean of the ipsilateral stapedial reflex threshold at 1,000, 2,000Hz was 87dB, 90dB on the male right, 87dB, 88dB on the male left, 89dB, 91dB on the female right, 87dB, 90dB on the female left. Depending on the tested frequencies, the stapedial reflex was not generated in 0.75% on the male, 0.5% on the female. 11) Eustachian tube function using the impedance audiometer malfunctioned in 7.5% of the cases. The mean difference between the peak level in the resting state and the peak level at inflation(+250mmH₂O), deflation(-250mmH₂O) was 8mmH₂O, 14mmH₂O on the male right, 9mmH₂O, 12mmH₂O on the male left, 9mmH₂O, 13mmH₂O on the female right, 9mmH₂O, 13mmH₂O on the female left. 12) The mean difference between the SRT and the PTA was -1dB on the male right, 0dB on the male left, -1dB on the female right, 0dB on the female left. 13) The mean difference between the MCL and the SRT was 42dB on the male right, 43dB on the male left, 42dB on the female right, 42dB on the female left. 14) The mean dynamic range was 98dB on the male right, 99dB on the male left, 99dB on the female right, 100dB on the female left. 15) The mean of the contralateral stapedial reflex threshold(Sensation Level) at 500, 1,000, 2,000, 4,000Hz was 84dB, 87dB, 80dB, 87dB on the male right, 84dB, 87dB, 84dB, 87dB on the male left, 85dB, 87dB, 80dB, 88dB on the female right, 85dB, 90dB, 85dB, 88dB on the female left. 16) The mean of the ipsilateral stapedial reflex threshold(Sensition Level) at 1,000, 2,000Hz was 89dB, 82dB on the male right, 89dB, 83dB on the male left, 90dB, 82dB on the female right, 91dB, 85dB on the female left.
