Abstract：FFT is a fast algorithm of discrete Fourier transform. This paper studies the acoustic characteristics by using MATLAB applying on FFT knocking at different corundum abrasive ceramic grinding wheel. It is found that the different obvious acoustic characteristics of alumina ceramic wheel, by making the characteristics of acoustic signal which can not be observed in the time domain transforming to the frequency domain signal. Through the comparison of different sample point amplitude frequency diagram, selecting the best sampling points, the feature parameters are extracted by drawing two corundum abrasive ceramic wheel frequency image and phase diagram. The results show that the FFT can extract the spectrum signal of acoustic characteristics from different corundum ceramic grinding wheel and this way pro-vides a method for further research on ceramic materials performance characterization based on acoustic principle;It has high correlation of Al2 O3 content in alumina and the characteristics of the acoustic parameters.
