정상청력자에서 순음청력계기의 각 주파수별 발진음에 대한 의성어 표현： (2) 협대역잡음에 대하여

Background and Object: We have used the pure tone audiometer or tinnitometer for checking tinnitus pitch. And we have also used the pure tone of audiometer for tinnitus pitch checking. But if there was not suitable sound at the pure tone, we can use the narrow-band noise. So when we know the onomatopoeia of the narrowband noise of each frequency of audiometer, we can make a reverse use of presuming the tinnitus frequency of tinnitus patients. Subjects and Method: The most comfortable level sound of narrow-band noise of nine frequencies (125, 250, 500, 1,000, 2,000, 3,000, 4,000, 6,000, 8,000 Hz) of the pure tone audiometer was given for 5 – 10 sec. to the 100 normal hearers (32 males, 68 females) of third decade, then let them to record the onomatopoeia of each sound. Result: 1) “pi:, pu (𝖍 ), p^h (u:u𝖍 ), p^ha: , p^hw, p^hi: ” and “u (u𝖍 ), hu:(𝖍 ), hw, hi: , hui (𝖍 )” distributed in 125 to 2,000 Hz indiscriminately. 2) “tu (𝖍 ), t^h (u: ), t (u𝖍 )” and “k (u𝖍 ), k^h (u: , u𝖍 ), k^h (w𝖍 )” appeared at only 125 Hz. 3) “su (u𝖍 ), sw (u: ), si (ik'), sui (ik'), sju (u,u𝖍 ), sha, s^hai, s^hw, s^hin” distributed at all frequencies except 125 Hz. 4) “ts^hi (i: ,ik'), ts^hui (i: ,ik'), ts^hin, ts^hw (𝖍 ), tsi (ik') are expressed as more 92% in only 3000 Hz or high frequencies. 5) At 125 Hz “u (u𝖍 ), hu: (𝖍 ), hw, hi: , hui (𝖍 )” are predominant in male, “pi: , pu (𝖍 ), p^h (u: u𝖍 ), p^ha: , p^hw, p^hi: ” are in female statistically. Conclusion: We suggest that expression test of tinnitus should be examined with not only pure tone but also narrow-band noise of audiometer for checking out exact onomatopoeia.
