The invention discloses a particle impact noise detection analyzer, and the analyzer controls an excitation device to carry out vibration, impact and rotation, and enable redundant materials in a detected part to generate a displacement relative to a housing and generate a sound wave signal. The signal is transmitted to a host through a sensor, and the host and solidification software carry out automatic comparison, analysis and judgment of types of redundant materials and generate a test report. The analyzer can judge and analyze whether there are movable redundant materials in small, middle and large aviation, aerospace, electron, weapon and ship equipment or not, and analyzes the types of the redundant materials. The beneficial effects of the invention are that the analyzer achieves the multi-point synchronous testing and modularized combined testing of the size of a platform top, independently distinguishes the signals of all detection points, customizes a movement execution program, achieves the simultaneous inputting of 4-64 detection signals, can be flexibly attached to the irregular curved surface of a non-plane detected part, guarantees that the transmission of signals is not attenuated, and analyzes the number and material of movable redundant materials through combining a database.
