Explanation

• As seen in the test method of the Unison jack-up system, by installing a isolated wall system on the slope of the room, it is installed with various materials to obtain more noise transmission loss. There is also a way to effectively reduce noise by using lighter weight channel, sound absorption board (80K, 100mmTHK) asbestos fabric, and gypsum oil plate, but since the surface density (kg/㎡) of the entire material is not large, it must be constucted as isloated system under NC-40 criteria. At this time, vibration block system UNSB or USB are installed at intervals of 900 to 1200 to prevent the transmission of solid vibrations, or solid sounds, of walls caused by sound pressure in the room (air conditioning room, machine room, etc.). The natural frequency of the products at this time shall not exceed 10 Hz. In addition, UWM is installed on the bottom of the double or light structural wall, and both sides in contact with the ceiling can be supported with UAB to absorb the shaking of the wall.
