地铁和隧道通风亭设计中气流噪声值的确定

Determination of Air Flow Noise Value in Design of Ventilation Shaft of Metro &Tunnel

根据地铁和隧道通风亭风口型式与噪声值之间关系,提供三种不同型式百叶风口在不同风速条件下距风口1 m处的气流噪声实测值和风亭设计注意事项,可供设计选用和参考。

According to the relationship between the louver type of ventilation shaft in metro & tunnel and noise value,the article presents three different types of louver with measured values of air flow noise of 1m away from the louver under different air speeds and design points for attention to be considered in ventilation shaft design for reference.
