Abstract：The signal preprocessing and noise reduction analysis methods of tunnel rock burst were mainly discussed，aiming to extract efective sound signal informationand identifyrock burst signals.The sound signals，including steps such as pre-emphasis，framing，windowing，and endpoint detection，were pre-processed. Diferent types of noise signals，such astruck transportation noise，concretebreaking noise，blasting noise and drilling noise，were distinguishdand identified.According to the diferentamplitude ranges，the light，medium and strong rock bursts were classified，and the signal graphics after noise reduction were displayed.
