声传播的计算并不困难,但是它枯燥无味并且耗费时间。必须在考虑了各种不同的衰减如空气衰减、地面情况、封闭结构、反射结构、声屏障意的情况下,对各倍频程分别计算。有时必须考虑声源的指向性和来自若干个声源的声音的叠加。然后,对于下一个受声点,全部计算必须再重复一遍,如此类推。这种计算的重复性恰好可以用数字计 Acoustic calculation is not difficult, but it is boring and time-consuming. Each octave must be calculated separately, taking into account the various attenuations such as air attenuation, ground conditions, enclosed structure, reflective structure, and sound barrier. It is sometimes necessary to consider the superposition of sound source directivity and sounds from several sound sources. Then, for the next affected point, all calculations must be repeated, and so on. The repeatability of this calculation can be calculated numerically
