TL;DR: In this paper, a sound detection device consisting of an acquisition module, an AFE (Analog Front End) module and a processing module is presented, wherein the acquisition module is used for acquiring environment sound pressure information and outputting sound pressure analog signals; the AFE module was used for amplifying the sound pressure analogue signals, converting the sound-pressure analog signals into sound pressure digital signals, carrying out nonlinear compensation and temperature compensation processing on the soundpressure digital signals and then outputting digital correction signals; and the processing module was preset with a data association table and a
