口琴簧片振动频率的理论与实验研究

Theoretical and Experimental Studies of the Vibration Frequency of Harmonica Reed

口琴是常见的乐器之一。通过推导了口琴簧片振动频率的计算公式,进而揭示了簧片几何尺寸对振动频率的影响,并对录制好的口琴音频文件进行快速傅里叶变换(FFT),从而推断口琴簧片振动的频率。

Harmonica is one of the most common instruments.This paper has given the expressions of the frequency of the harmonica reed,and explained the relationship between the geomatric dimensions of the reed and its frequency.Furthermore,we made a Fast Fourier Transform on a recorded audio file and calculated the frequency of the reed.
