A noise reduction device for air suspension systems is provided to change the shape of a joint, which connects an air suspension system and a storage tank, thereby reducing noise generated by pressure difference between an air spring and the storage tank. A noise reduction device for air suspension systems comprises: a storage tank(32) with an entrance(33); a joint(40) whose some part is inserted into the entrance and connected to the storage tank; and a flow path(31) connected to the joint. The joint consists of: a first joint(41) combined with the flow path; a second joint(42) extended from the first joint and connected to the outer circumference of the storage tank; and a third joint(43) extended from the second joint and penetrated through the entrance. |
