Active Noise Control Strategy for Road Traffic Noise Energy Penetrating Windows in High-rise Buildings Using a Vibration Active Control Device

摘要

In this paper, we build on an experimental investigation published in Inter-Noise 2015, which examined traffic noise using acoustical sensors and a vibration sensor set on windows in high-rise buildings. Moreover, we extensively study the relationships between the energy efficiencies of glass absorption σ_(abs), glass surface radiation σ_(rad), and the transmission loss (TL) insulation levels of windows, doors, walls, and other structures to decrease road traffic noise indoors. To achieve effective noise control, an active vibration control device set on the glass pane is proposed to change the direction of noise energy transfer from perpendicular to the glass pane face to parallel to the glass pane. Finally, the noise mitigation effectiveness is theoretically calculated for different conditions and efficiency levels.
