对英国中学的声学情况进行了调查。本研究在13间学校的185个空置空间量度室内声学参数及背景噪音水平，以提供有关中学典型声学环境的资料。未占用的声学和噪声数据与空间的各种物理特性相关。房间的高度和玻璃窗的数量与空置混响时间有关，因此需要加以控制，以将混响降低到适合教学和学习的水平。对空置数据的进一步分析表明，2003年在英格兰和威尔士实行的与学校声学有关的立法使符合现行标准的学校空间数量增加了约一倍。在274节课期间，还测量了噪音水平，以检查中学教学活动期间产生的典型水平，并调查声学设计对教室工作噪音水平的影响。比较未占用和占用的数据表明，未占用的声学条件影响课程期间发生的噪音水平。它们还与中断课程所花费的时间有关（例如，学生说话或喊叫），因此也可能对学生在课堂上的行为产生影响。
An acoustic survey of secondary schools in England has been undertaken. Room acoustic parameters and background noise levels were measured in 185 unoccupied spaces in 13 schools to provide information on the typical acoustic environment of secondary schools. The unoccupied acoustic and noise data were correlated with various physical characteristics of the spaces. Room height and the amount of glazing were related to the unoccupied reverberation time and therefore need to be controlled to reduce reverberation to suitable levels for teaching and learning. Further analysis of the unoccupied data showed that the introduction of legislation relating to school acoustics in England and Wales in 2003 approximately doubled the number of school spaces complying with current standards. Noise levels were also measured during 274 lessons to examine typical levels generated during teaching activities in secondary schools and to investigate the influence of acoustic design on working noise levels in the classroom. Comparison of unoccupied and occupied data showed that unoccupied acoustic conditions affect the noise levels occurring during lessons. They were also related to the time spent in disruption to the lessons (e.g., students talking or shouting) and so may also have an impact upon student behavior in the classroom.
