The present invention involves: detecting the number of rotations of a ship engine (X), and calculating the specific frequency of the ship engine (X) on the basis of the number of rotations; adjusting the pressure inside a chamber (20) according to an increase/decrease in the specific frequency of the ship engine (X) or for each prescribed interval of time; switching the volume of an air spring (16) by connecting/blocking the air spring (16) to/from an auxiliary tank (18) by opening and closing a volume-switching electromagnetic valve (60); and matching the internal pressure of the air spring (16) and the pressure inside the chamber (20) with one another by opening/closing a pressure-adjustment electromagnetic valve (36).
