Ventilation and sound insulation unit structure and ventilation sound barrier
The invention discloses a ventilation and sound insulation unit structure and a ventilation sound barrier. The ventilation and sound insulation unit structure is a sub-wavelength hollow structure and comprises an outer shell, an inner shell and a sound insulation module, and the outer shell defines a first channel; the inner shell is arranged in the first channel and defines a second channel, an inlet of the second channel is adjacent to an inlet of the first channel, and an outlet of the second channel is adjacent to an outlet of the first channel; and the sound insulation module is connected with the inner wall of the outer shell and the outer wall of the inner shell, a third channel is formed between the outer shell and the inner shell, an inlet of the third channel is close to an inlet of the first channel, an outlet of the third channel is close to an outlet of the first channel, and a sound transmission path of the third channel is longer than that of the second channel. Based on the Fano-like interference effect, the effect of shielding external noise while allowing airflow and illumination to pass through is achieved.
本申请公开一种通风隔声单元结构及通风声屏障，该通风隔声单元结构为亚波长空心结构，包括外壳、内壳和隔声模组，其中，外壳限定出第一通道；内壳设置在第一通道内，内壳限定出第二通道，第二通道的入口邻近第一通道的入口，第二通道的出口邻近第一通道的出口；隔声模组连接外壳的的内壁与内壳的外壁，隔声模组在外壳与内壳之间构造出第三通道，第三通道的入口靠近第一通道的入口，第三通道的出口靠近第一通道的出口，第三通道的传声路径长于第二通道的传声路径。本申请基于类法诺干涉效应，实现了允许气流、光照通过的同时屏蔽外界噪声的效果。
