摘要
针对城市交通噪声及空气污染严重的现状,结合现有通风隔声窗的不足,设计了一种基于主动降噪技术、被动降噪技术及空气过滤技术的自然通风隔声净化窗,以解决自然通风与隔声降噪间的矛盾,提升现有隔声窗针对中低频噪声的隔声性能,并净化进入室内的空气。同时通过实验验证了设计的可行性。
In view of the situation of urban traffic noise and air pollution, combined with the shortage of the existing ventilation and sound insulation window, this paper introduces a natural ventilation and sound insulation window based on the active noise reduction technology, passive noise reduction technology and air filtration purification technology. This product can solve the contradiction between the natural ventilation and noise reduction, improve the existing sound insulation window for sound insulation performance of low frequency noise, and make the air clean. At the same time, the feasibility of the design is verified by experiment.
