Abstract: A general microphone and PC sound card is used to acquire fan noise;FFT power spectrum is used for fan noise analysis on frequency domain,and a conclusion of the attributes and varying trend of fan noises is made.

Key words: Fast Fourier Transform(FFT), power spectrum, fan noise, LabVIEW, unbalanced vibration

摘要: 利用普通麦克风及声卡对散热风扇振动噪音进行采集,并利用FFT功率谱对风扇振动噪音进行频域分析;通过实验总结了风扇振动噪音的幅频特性及其变化规律。

关键词: 快速傅里叶变换(FFT), 功率谱, 风扇噪音, LabVIEW, 不平衡振动
