Abstract

This paper describes the acoustical conditions of elementary school and high school classrooms as well as university classrooms in Korea and suggests a need for Korean acoustic standards and guidelines for classroom design. Current standards and guidelines of classroom acoustics in several countries were briefly introduced to understand their acoustical performance criteria for background noise levels and reverberation times, and noise isolation design requirements in various types of classrooms. The results of several acoustic survey of domestic classrooms in elementary school, high school, and university were described and compared to provide information of the acoustic characteristics of Korean school classrooms. The survey includes occupied and unoccupied data on the acoustical conditions, noise levels, and noise isolation performance in the classrooms. Acoustical parameter values for achieving ‘good’ speech intelligibility in active university classrooms were also presented.

본 논문에서는 국내 초·중·고 및 대학교 학습공간의 음향 상태에 관해 설명하고 국내 교육시설의 음향 기준 제정의 필요성을 제시하였다. 여러 나라의 학교시설 내 다양한 학습공간에서 요구되는 배경소음, 잔향시간, 그리고 차음 설계의 음향 기준을 이해하기 위해 학교시설 음향설계기준 및 지침을 소개하였다. 국내 초·중·고 및 대학교 학습공간의 음향 상태를 파악하기 위해 현장 측정 결과를 바탕으로 하였으며, 그 결과에서는 공석과 만석 상태의 음향 특성, 배경 소음레벨, 그리고 차음성능을 제시하여 비교하였다. 실제 대학 강의 현장에서 좋은 음성 명료도를 성취하기 위한 음향지표 값도 제시하였다.
