Composite phononic crystal noise reduction window
The invention discloses a composite phononic crystal noise reduction window, which comprises a window main body and N rows of composite phononic crystal arrays arranged in the window main body, each row of composite phononic crystal array specifically comprises three local resonance phononic crystals with different structural sizes and sound absorption materials adhered to the inner walls and the outer walls of the local resonance phononic crystals, and N is a positive integer. According to the invention, a good noise reduction effect can be achieved, the occupied area is small, and good ventilation and lighting performance is achieved.
本发明公开了一种复合声子晶体降噪窗口，包括：窗口主体和设置在所述窗口主体内的N排复合声子晶体阵列，其中，每排复合声子晶体阵列具体包括：三个不同结构尺寸的局域共振声子晶体和黏附于所述局域共振声子晶体内外壁的吸声材料，其中，所述N为正整数。本发明能够获得良好的降噪效果同时，占地面积小，且具有良好的通风和采光性能。
