| 설명 | 귀가 들리는 정도를 측정하는 검사. 청각검사라고도 한다. 소리나 목소리가 잘 들리는지의 여부 등 청각의 예민한 정도를 측정하는 일이다. 검사에는 청력계나 소리굽쇠 등의 기구에 의해서 얻는 음원, 즉 순음을 사용하며, 사람의 목소리나 시계소리 등도 음원으로 사용된다. 또 음파가 전파되는 매질에 따라 기도 청력검사와 골도 청력검사로 구별되기도 한다. 검사의 내용으로는 청각의 상하음계나 최소 가청문턱값의 검사를 비롯하여, 충분히 들리는 소리를 사용하여 그것이 들리는 상태를 조사하는 문턱값검사(소리의 크기와 상태의 검사, 세기의 판별역검사 등) 외에 음향자극의 반응으로부터 타각적으로 조사하는 방법도 있으며, 이것은 주로 갓난아기나 정신병환자에 대하여 사용된다. 주로 청력계가 사용되고, 청력은 데시벨(dB)로 표시된다. 정상인은 0dB이고, 난청자일수록 그 수가 커지며, 60dB이상은 상당히 난청이고, 80dB 이상이면 귀머거리이다. |
