Five-membered silicon microphone device for sound source localization rock sample fracturing point and localization method

Abstract

The invention discloses a five-membered silicon microphone device for sound source localization of rock sample fracturing points and a localization method. The five-membered silicon microphone device comprises a five-membered silicon microphone array device, a multi-channel acquisition system and a rock sample loading device, sound signals generated by fracturing in a rock sample uniaxial experiment are obtained through five-membered silicon microphone devices, the five-membered silicon microphone devices which are specifically arranged are arranged to solve rock sample fracturing sites under the non-contact condition, and three-dimensional space coordinates of the fracturing sites are solved through the arrival time difference of the sound signals. A data processing algorithm is used to carry out noise reduction and filtering processing on sound signals, and a lead breaking experiment is used to calibrate the sound source positioning effect of the five-membered silicon microphone device. The invention provides a non-contact measuring device and method for researching three-dimensional coordinates of a fracturing site in a sound source localization rock sample loading experiment process.
