Because muzzle impulse noise could cause damage to or have an influence on the operator,the effective protective measures should be taken.Therefore,correct analysis of impulse noise characteristics is very significant.Considering the shortcomings of fast Fourier transform method（FFT）in analysis of muzzle impulse noise frequency characteristics,wavelet energy spectrum method is put forward.Based on specific experiment data,the frequency characteristics and spectral energy distribution can be obtained.The experiment results show that wavelet energy spectrum method is applicable in muzzle impulse noise characteristic analysis.
