In order to improve material formulations for the current paper-making process, in order to make full use of resources, reduce development costs, the paper crisp detection method based on the audio band. As the main method to specify the paper sample audio segment signal detection component, research paper crisp distinction,sound sensor acquisition banging sound in the audio signal analysis. Paper sample system for different degrees of crisp, proposed the idea to use the audio band detection, optimizing the audio signal obtained using the Fourier transform and the background difference method, paper crisp crisp degree detection of different components of the paper detection has clearly differentiated.
