These levels come from outside activities that penetrate the classroom structure, from teaching activities, and other noise generated inside, which can be exacerbated by room reverberation.
这些（噪音）可以是穿透教室建筑结构的室外活动声、教学活动的声音以及室内产生的其它各种声响，这些声音都会因为房间的回声效果而被放大。
It does this by fitting small piezoelectric acoustic sensors to parts of the structure to detect the particular frequency of noise caused by a crack in aircraft-grade aluminium.
把小型压电声传感器安装到这种构造部位上，检测由航空级铝材裂纹所致的特定频率的噪音，靠这样就能监测飞机裂纹。
