Abstract： In order to solve the problems that the traditional gear noise measurement is influenced by human factors ，the gear mesh noise measurement and analysis system based on ARM and DSP was designed. The DSP was used to complete the noise signal acquisition and data preprocessing. A set of signal analysis and graphical display software was developed based on WinCE 6.0. Combined with touch screen system，the test parameters input and communication settings were completed. By experimental verification in Beijing Gear Works site，it shows that the system can analyze the gear glitches and other noise signal frequency，and could be used for the analysis of processing gear.
