A supersound output apparatus is provided to reduce the consumption power by considering the output change of the supersound according to the water level change. A supersound output apparatus is composed of a storage room(100) in which an object(110) is stored; a supersound generator(80) supplying the supersound to the storage room; and an out valve(70) mounted at the side surface of the storage room to keep the water level of the storage room at the position where the supersound is a normal wave. A water level sensor(50) is placed at the side surface of the storage room to sense the water level in the storage room. A control unit(60) is electrically connected to the water level sensor to read the water level in the storage room.
