Abstract Snoring noise usually affects sleeping of the other persons in one room. In the paper, to re-duce snoring noise, the rigid baffle with the finite height and width is placed between the two persons. The bed and bedhead are modelled as the rigid semi-infinite plates separately and vertically each other. By simulation, noise reduction producing by placing the baffle is calcu-lated. And noise cancellation change is discussed by adjusting the height and the width of the baffle. Due to the limited size of the baffle, a part of noise wave is diffracted and goes around to the off side of the baffle. To cancel the residual noise due to sound diffraction two loud-speakers as secondary sources are arranged in the barrier. Finally the total reduction of the in-tegrated passive and active system is given.
