Sound insulation ventilating window
The invention belongs to the field of building sound insulation and noise reduction, and particularly relates to a sound insulation ventilation window which comprises a window body, the window body comprises an outer window 1 and an inner window 2, the outer window 1 and the inner window 2 are fixedly connected, a protruding strip 3 is arranged on the outer surface of the outer window 1, air inlet holes 31 are formed in the two sides of the protruding strip 3 respectively, the air inlet holes 31 in the two sides of the protruding strip 3 are oppositely formed, and air outlet holes 21 communicated with the air inlet holes 31 are formed in the outer surface of the inner window 2. Compared with the prior art, the air inlets are not formed in the outer surface of the window sash in the forward direction, introduction of sound waves is reduced, on the other hand, the air inlets are formed in the opposite directions in pairs, most noise is reduced or eliminated according to the anti-phase counteracting principle of the sound waves, and the silencing effect is better.
本发明属于建筑隔声降噪领域，具体涉及一种隔声通风窗，包括窗体，所述窗体包括外窗1与内窗2，外窗1与内窗2之间固定连接，外窗1外表面设置凸条3，凸条3两侧分别设置进气孔31，凸条3两侧的进气孔31相对设置，内窗2外表面设置与进气孔31连通的出气孔21，相对于现有技术，本发明进气口不在窗扇外表面正向设置，减少声波的传入，另一方面，进气口之间两两对向设置，使得利用声波的反相位抵消原理，降低或消除大部分噪声，消声效果更好。
