大家知道,光学实驗一定要在暗室中或有特殊反射鏡的条件下来作,否則外面的太阳光或房間中的灯光就会干扰要作的实驗。声学实驗也是这样,例如揚声器和传声器的测試和改进,吸声和隔声材料的检定和研究制造,声波繞射和散射等特性的研究,都必須控制或减少外界干扰声波的影响,因此,就需要建造特別为声学測試和研究用的专用声学实驗室。房間中的声波为了进一步說明为什么必須設 As we all know, optical experiments must be done in the darkroom or with special reflectors, otherwise the outside sunlight or the lights in the room will interfere with the experiments to be performed. The same is true for acoustic experiments, such as the testing and improvement of loudspeakers and microphones, the testing and manufacturing of sound-absorbing and sound-insulating materials, and the study of properties such as acoustic diffraction and scattering, all of which must control or reduce the influence of external disturbances on acoustic waves. It will require the construction of a special acoustics laboratory, especially for acoustic testing and research. The sound waves in the room must be set for further explanation
