通过用示波器和计算机进行共振干涉法（驻波法）测量声速的比较，证明用计算机代替示波器进行测量声音速度的实验不但是可行的，而且还有其独特的优点。首先，多用途的计算机比较普及，操作简便，而示波器昂贵而且操作复杂，对于刚刚进入大学一年级的新生来说，一般很难准确操作。其次，计算机测量声速可以很明显地找到各个共振点，并且不受调整时间的限制。
通過用示波器和計算機進行共振榦涉法（駐波法）測量聲速的比較，證明用計算機代替示波器進行測量聲音速度的實驗不但是可行的，而且還有其獨特的優點。首先，多用途的計算機比較普及，操作簡便，而示波器昂貴而且操作複雜，對于剛剛進入大學一年級的新生來說，一般很難準確操作。其次，計算機測量聲速可以很明顯地找到各箇共振點，併且不受調整時間的限製。

Compared with an oscilloscope, the experiment, in which the resonance interference method is used to measure the speed of sound with a computer aid, is not only feasible, but also has its unique advantages. First of all, the multipurpose computer is relatively popular and easy to operate, while the oscilloscope is ex-pensive and complicated to be operated by the freshmen of a college. Secondly, each resonance point can be found clearly if the speed of sound is measured with a computer aid, and the experiment is not limited by time.
