Traffic noise self-adaptive sound absorption barrier and method and rubber foam sound absorption concrete layer
The invention provides a traffic noise self-adaption sound absorption barrier and method and a rubber foam sound absorption concrete layer, and belongs to the technical field of noise reduction, and the traffic noise self-adaption sound absorption barrier comprises a micro-perforated plate, the rubber foam sound absorption concrete layer and an adjustable sound absorption cavity which are sequentially arranged in the transmission direction of traffic noise. The rubber foam sound absorption concrete layer is used for absorbing middle-frequency-band traffic noise, the micro-perforated plate and the adjustable sound absorption cavity are used for forming a resonance sound absorption screen body to absorb low-frequency-band traffic noise, and noise reduction treatment of the traffic noise with different characteristics in different scenes is achieved. And finally, noise reduction processing of the medium-frequency-band traffic noise and the low-frequency-band traffic noise is realized.
本发明提出了交通噪声自适应吸声屏障及方法和橡胶泡沫吸声混凝土层，属于降噪技术领域，其包括沿交通噪声的传递方向依次设置的微穿孔板、橡胶泡沫吸声混凝土层和可调节吸声空腔。本发明利用橡胶泡沫吸声混凝土层吸收中频段交通噪声，利用微穿孔板与可调节吸声空腔形成共振吸声屏体吸收低频段交通噪声，实现不同场景中不同特征的交通噪声的降噪处理，最终实现中频段交通噪声和低频段交通噪声的降噪处理。
