In this paper, we present an improved, ZigBeebased, gridenabled airport noise monitoring method, as original airport noise monitoring method is not very suitable to airport noise monitoring. The proposed method widely deploy sensor nodes in the airport and its surrounding areas as grid,.The improved method has huge number of sensor nodes which are intensive and cheap, so the method can apply to airport noise monitoring business such as noise monitoring, flight track reconstruction, noise counter map portrayal. Through a series of simulation we proposed a layout method of sensor nodes in gridenabled airport noise monitoring. Finally we implement this gridenabled airport noise monitoring method and nodes layout method in Tianjin Binhai International Airport and evaluate the performance.
