Active noise control system is an advanced noise management technology that neutralizes noise by generating sound waves with opposite phase to intrusion noise,thereby achieving noise reduction effect. This article delves into the fault diagnosis technology of electroacoustic devices based on active noise control systems,and provides a detailed introduction to the application of electroacoustic device fault diagnosis technology,including the overall design scheme,the design of a fault diagnosis system based on impedance characteristics and signal root mean square error method,and the implementation of a secondary sound source and error microphone fault diagnosis system based on STM32 to ensure efficient operation and long-term stability of the system.
