Zusammenfassung:The invention relates to the technical field of production of sound-absorbing materials, in particular to a sound-absorbing material quality control system and method based on a tuning band-pass filter, and the method specifically comprises the following steps: sending a sound signal with the frequency of 30Hz-20KHz to a detected sound-absorbing material through a sound generator, the vibration response signals are screened and filtered through a real-time sensor network and a self-adaptive tuning band-pass filter; comparing with a historical comparison database to judge whether the sound absorbing material to be detected has a quality problem or not; and finally, feeding back and disclosing a real-time monitoring result of the detected sound-absorbing material to a production line, and guiding or adjusting production actions. The problems that in the prior art, traditional quality detection of the sound-absorbing material has extremely high dependence on a testing environment, and a testing result is easily
