The utility model discloses a theory of operation: sound absorption is the phenomenon of energy loss after sound waves impact the surface of a material, and the sound absorption can reduce the indoor sound pressure level. The sound absorption principle is that a channel for sound to enter is reserved, but the sound cannot come out once the sound enters, the sound drills in the channel due to the fact that the channel is too long, and the left and right impacts gradually consume energy in the process, so that the sound absorption effect is achieved. When sound is transmitted to the window body in the air, most sound waves are reflected by the window sash 1, the window frame 2 and the rubber strip 7 between the window sash and the window frame, and the double-layer glass 6, and the rest sound waves are introduced into the window sash 1 and the window frame 2 and are blocked and silenced in the following mode.
