采用主被动控制技术的自然通风隔声窗研究
Natural Ventilation and Sound Insulation Windows Based on Active and Passive Control
摘要
Abstract
The existing natural ventilation and sound insulation windows are unlikely to solve the problem of low-frequency noise effectively. In this paper, the active control technology is applied to the natural ventilation and the sound insulation windows. The polyurethane sound-absorbing cotton and micro-perforation panel are used. It is proved that the active control technology can effectively reduce the noise in 100 Hz-400 Hz frequency range, the passive control works well in the frequency range above 400 Hz, the sound insulation performance of the sound insulation window is nearly the same as that of closed window, and the noise at the outlet is reduced by 32.6 dB (A).关键词
