Abstract

To solve the problem of that the existing sound insulation window cannot control the low-medium frequency noise effectively, active and passive noise control technologies are used in the internal and external staggered open channel to broaden the noise reduction frequency range of the existing sound insulation window and ensure natural ventilation.The experiment research shows that active noise control technology can bring more than 15dBA extra noise reduction at low-medium frequency and passive noise reduction technology can bring more than 10dBA extra noise reduction at medium-high frequency, the whole window ensured natural ventilation at the same time achieves 42dBA noise reduction .
