Abstract

The present study investigates the acoustic conditions of active classrooms based on the speech and noise levels. The speech and noise levels were measured in 29 classrooms during 57 actual classes in Korean schools. The effects of occupants and classroom activities on the speech and noise levels in occupied classrooms were examined. The present results indicate a general trend of decreasing noise levels by 6 to 12 dBA with increasing age of the students. Additionally, the noise levels in the classrooms were found to be closely related to the type of classroom activities. The results indicate that the acoustic standards should recommend reducing the unoccupied noise levels in order to minimize noise levels in active classrooms.

본 연구에서는 국내 초·중·고 및 대학교 학습공간의 재실 음향 상태를 조사하기 위해 수업 중인 교실 및 강의실 29개 현장을 측정하였다. 총 57곳 수업 현장에서의 음성 및 소음 레벨을 바탕으로 재실자 및 학습 활동유형에 따른 재실 음향 상태를 조사하였다. 학습 연령이 높아질수록 수업 현장에서의 소음 레벨은 약 6~12dBA 감소하였다. 그리고, 학습 활동 특성이 수업 현장의 소음 레벨에 영향을 주는 것으로 나타났다. 국내 교실 및 강의실의 높은 음성 명료도 성취를 위해 공실 조건에서 교실 및 강의실 내 소음 레벨을 최소화하여 재실 조건에서 권장 SNR값의 조성이 가능하게 해야 한다.
