초록

청각선별에서 반응 역치는 검사 환경 잡음, 청각기관 생리적 특성, 과도한 음원 노출 등에 따라 다르게 나타난다. 이 연구 목적은 청각선별을 통과한 소아의 주파수별 가청역치에 대한 정보를 획득하는데 있다. 연구 대상은 언어치료센터와 지역아동센터에 다니는 3.3세부터 16.3세($9.01{\pm}2.52$) 사이의 110명으로 하였고, 이들의 소아 청각 선별 결과를 후향적으로 분석하였다. 청각선별은 고막운동성계측(Tympanometry), 등골근반사(acoustic reflex threshold), 자동화 이음향방사(automated otoacoustic emission), 순음청각선별(pure tone screening)을 시행하였다. 대상자들은 모두 청각선별 정상 기준에 포함되었다. 주파수별 가청역치 차이는 반복측정 분산분석 하였다. 결과: 가청역치 평균은 500, 1,000, 2,000, 4,000 Hz의 순서로 우측 귀 $16{\pm}6.49$, $11.5{\pm}4.79$, $6.86{\pm}4.99$, $5.95{\pm}6.65$ dB HL, 좌측 귀 $15.68{\pm}6.01$, $9.95{\pm}5.24$, $5.72{\pm}5.21$, $5.63{\pm}7.04$ dB HL로 각각 관찰되었다. 주파수 사이에는 500Hz와 1,000, 2,000, 4,000 Hz(p=.000), 1,000과 2,000, 4,000 Hz(p=.000)로 유의한 차이가 있었다.

Responded threshold level in hearing screening depends on the noise level of test surroundings, physiological characteristics of hearing organs, excessive sound source exposures, and so on. The purpose of this study is to obtain the basic information of hearing threshold level at each frequencies in children with passed hearing screening. Subjects were 110 children, aged were from 3.3 to 16.3 ($9.01{\pm}2.52$), who were at private speech language pathological clinics and daycare centers. Methods of Hearing screening were tympanometry, acoustic reflex threshold, automated otoacoustic emission, and pure tone screening. The subjects were in normal criteria of hearing screening. The differences of hearing threshold among ages and frequencies were measured by means of repeated measures ANOVA. The mean of hearing thresholds level was observed $16{\pm}6.49$, $11.5{\pm}4.79$, $6.86{\pm}4.99$, $5.95{\pm}6.65$ dB HL in the right ear and $15.68{\pm}6.01$, $9.95{\pm}5.24$, $5.72{\pm}5.21$, $5.63{\pm}7.04$ dB HL in the left ear, in frequency of 500, 1,000, 2,000, 4,000 Hz respectively. There was a significant difference between 500 and 1,000, 2,000, 4,000 Hz (p=.000), between 1,000 and 2,000, 4,000 Hz (p=.000).
