高等学校合班教室声学指标缺陷及解决方法——以沈阳建筑大学为例

The Research of Acoustic Indicators Defects and Solutions of the College Classrooms——Take Shenyang Jianzhu University as an Example

高等学校教室声学环境的质量,直接影响着教师的教学质量。针对沈阳建筑大学合班教室声学指标缺陷(噪声干扰和混响时间过长)。通过隔声技术来隔绝噪声干扰和吸声设计技术来控制教室内的混响时间。利用隔声计算公式和混响时间公式进行理论分析。推导出满足教室声学指标要求的一般设计方法,为改善学校合班教室内的声学环境提供可行的设计方法。

Higher quality of acoustic environment of classroom directly affects the quality of teaching.Ac-cording to the acoustic indicators defects of the combined classroom in Shenyang Jianzhu University and the excessive noise and reverberation time,by acoustic noise isolation technology and acoustic design,we can control the reverberation time in the classroom.By using acoustic reverberation time formula and theoreti-cal analysis of the formula,we can derive indicators to meet the requirements of the general classroom a-coustic design.By doing so,we can improve the combined classroom acoustic environment by providing practical design.
