摘　　要：传统多普勒效应演示实验的声源杂音大且无法定量测量,实验结果可信度低.利用App软件"音频发生器"和"FreqCounter"及智能手机iPhone的声音传感器可以实现对不同条件下多普勒效应的定量测量,实验效果明显.Quantitative measurement cannot be realized in the traditional Doppler effect experi ment, and the noise of the sound source is big. Using the Apps of Audio Generator, FreqCounter and the sound sensor of the smart phone, quantitative measurement of Doppler effect under different conditions could be realized. The effectiveness of teaching was obviously improved.
