The invention relates to the technical field of prefabricated walls, in particular to a noise reduction type prefabricated wall and noise monitoring and adjusting device.The noise reduction type prefabricated wall comprises a body, a cavity is formed in the middle of the body, two hollow noise reduction cavities are formed in the cavity, and gaps are formed between the side walls, facing the side of the body, of the noise reduction cavities and the inner wall of the body; a plurality of noise reduction parts are installed between the two noise reduction cavities, a plurality of noise reduction assemblies are installed in the noise reduction cavities, a detection device is installed on the outer wall of the body, a plurality of detection sensors are evenly distributed on the outer wall of the body and electrically connected with the detection device, and the detection device is in signal connection with the noise reduction assemblies. The intensity of sound wave vibration is detected through the detection sensor, and according to the detected intensity of sound wave vibration, the silencing assembly adopts a corresponding silencing and noise reduction strategy; and through cooperation of the perforated plate resonance sound absorption structure, the anti-phase noise reduction assembly and the noise reduction part, noise is counteracted, and outward transmission of noise sound waves through the wall is reduced.
本发明涉及预制墙体技术领域，具体涉及一种降噪型预制墙体及噪音监测调节装置，包括本体，本体的中部设有空腔，空腔内安装有两个中空的降噪腔，降噪腔朝向本体一侧的侧壁与本体的内壁之间具有间隙，两个降噪腔之间安装有多个消音部，降噪腔的内部安装有多个消音组件，本体的外壁安装有检测装置，本体的外壁均布设有多个检测传感器，多个所述检测传感器均与检测装置电性连接，检测装置与消音组件信号连接，本发明通过检测传感器检测声波的振动的强弱，根据检测到的声波振动的强弱，使消音组件采用相应的消声降噪的策略；再通过穿孔板共振吸声结构、反相位降噪组件与消音部的配合，对噪声进行抵消，减少噪声声波透过墙壁向外传播。
