Building outer wall noise reduction structure
The invention discloses a building outer wall noise reduction structure. The building outer wall noise reduction structure comprises a first reflecting layer laid on the outer surface of an outer wall, a sound absorbing layer laid on the first reflecting layer. and a second reflecting layer laid on the sound absorbing layer. The noise reduction device has the beneficial effects that sound waves are reflected and absorbed in sequence, the reflection and the absorption are circulated, and the noise reduction function is remarkably improved.
本发明公开了一种建筑物外墙降噪结构，包括：第一反射层，其敷设于外墙外表面上；吸音层，其敷设于所述第一反射层上；第二反射层，其敷设于所述吸音层上。本发明具有将声波先后进行反射、吸收、反射、吸收循环往复，显著提升降噪功能的有益效果。
