Abstract
Sound absorbing device for the infrasound is studied, using the mass and the damping. Thin film is used as the mass and neodymium magnets are used as damping. The reflection coefficient and the transmission coefficient of the film with damping in the acoustic duct are calculated, and are compared with experiments. The neodymium magnet can be realized the damping needed for the proposed device. 3 dimension sound fields are also calculated by BEM with and without the proposed device. The successful results suggest that the proposed device is effective to reduce the infrasound.
