Sound insulation treatment of professional audio!Bar use audio Vendor

　　There are two main ways for noise to enter indoors. One is the noise of moving and static incident waves transmitted into the room through the wall, and then transmitted to the room through the air medium, as well as the noise transmitted through the air holes such as door cracks, window gaps, and air-conditioning ducts; the other is vibration noise, which is related to Other buildings with solid connections in this room will vibrate after being impacted, and then the noise will be transmitted to this room along the solid connection.

　　Professional sound insulation methods must be targeted. Projects that intermittently isolate dynamic and static transmission channels are often referred to as "sound insulation" projects. Projects that intermittently isolate "vibration sound" are also often referred to as "vibration isolation" projects. People generally refer to them collectively. For sound insulation.

　　Professional audio generally chooses the heavier (higher density) sound insulation material, the thicker the better. The plan is double-layered doors, double-layer walls, etc., which are better. The detailed sound insulation methods often used are the following:

　　1. Wall: Thick and heavy structure should be used for the wall, so as to prevent airborne noise. If conditions permit, double-layer walls can be installed. When installing sound-absorbing panels on the inner side of the wall, there should be a certain distance from the wall, which is essentially a double-layer wall.

　　2. Ceiling and carpet: If the listening room is located in the middle of a high-rise building, the noise from upstairs and downstairs can be introduced into the listening room through the ceiling and floor. In order to reduce the vibration sound transmitted into the room through these channels, a suspended ceiling can be set to isolate the noise from the sky, and the floor can be laid to isolate the noise from the air.

　　3. Door and window seams, pipes: It is possible to paste sealing tapes on door seams and window seams, which is the easiest way to deal with sound insulation.

　　4. Doors and windows: installing sound insulation doors and windows is the key to noise reduction. The transmission loss of the door depends on its weight, hardness and density. Generally, the sound insulation of wooden doors is 18dB. Increase the weight and thickness of the door to increase the sound insulation. Assuming that a double-layer door is installed and the center is filled with sound-absorbing materials, it can significantly absorb sound.

　　Assuming that the conditions are satisfied, the listening room windows of the home theater can be set to two layers, so that three layers of glass windows, the thicker the glass, the better, the glass and the frame are connected with special-shaped rubber strips, so that the sealing and elasticity are balanced, and the high-quality sound insulation The sound insulation function of the window can reach the effect of the 24cm brick wall.
