How to solve wall resonance noise.
Wall resonance noise is a common noise problem, usually caused by structural vibrations in buildings. This noise can affect the quality of life of the occupants and therefore needs to be addressed in a timely manner. Here are some ways to solve the resonant noise of the wall.
1.Find the cause.
First of all, it is necessary to find out the cause of the resonant noise of the wall. It may be caused by structural vibration of the building, vibration of equipment, external environment, etc. The level of noise can be determined by observation and testing.
2.Soundproofing.
For wall resonance noise, noise transmission can be reduced by sound insulation treatment. Soundproofing materials can be installed on the surface of the wall, such as soundproofing panels, soundproofing felt, etc. At the same time, it is also possible to install soundproofing materials inside the wall, such as soundproofing foam, soundproofing cloth, etc.
3.Structural reinforcement.
If the wall resonance noise is caused by structural vibration, the vibration can be reduced by structural reinforcement. Structural reinforcement measures such as steel frame and steel mesh can be installed on the surface of the wall to improve the stiffness and stability of the wall.
4.Equipment replacement or adjustment.
If the wall resonance noise is caused by the vibration of the equipment, the equipment can be replaced or adjusted to reduce the vibration. Low-noise equipment can be replaced, or the location and manner of installation of equipment can be adjusted to reduce vibration to the wall.
5.Improvement of the external environment.
If the wall resonance noise is caused by the external environment, the noise transmission can be reduced by improving the external environment. Natural noise barriers such as green belts, trees, etc., can be added, or sound insulation materials can be added around buildings to reduce the spread of noise.
The best way to isolate low-frequency noise.
Low-frequency noise is a common noise problem that is usually caused by vibrations in equipment, machinery, etc. Here are some ways to solve low-frequency noise.
1.Soundproofing.
For low-frequency noise, noise transmission can be reduced by sound insulation. Soundproofing materials can be installed on the surface of the wall, such as soundproofing panels, soundproofing felt, etc. At the same time, it is also possible to install soundproofing materials inside the wall, such as soundproofing foam, soundproofing cloth, etc. In addition, sound insulation materials can be added to doors and windows to reduce the transmission of low-frequency noise.
2.Structural reinforcement.
If low-frequency noise is caused by structural vibration, the vibration can be reduced by structural reinforcement. Structural reinforcement measures such as steel frame and steel mesh can be installed on the surface of the wall to improve the stiffness and stability of the wall. At the same time, it is also possible to add support structures inside the building to reduce the vibration of the structure.
3.Equipment replacement or adjustment.
If the low-frequency noise is due to the vibration of the device, the device can be replaced or adjusted to reduce the vibration. Low-noise equipment can be replaced, or the location and manner of installation of equipment can be adjusted to reduce vibration to the wall. In addition, shock absorbers and cushions can be added to the equipment to further reduce the transmission of vibrations.
4.Improvement of the external environment.
If low-frequency noise is caused by the external environment, the transmission of noise can be reduced by improving the external environment. Natural noise barriers such as green belts, trees, etc., can be added, or sound insulation materials can be added around buildings to reduce the spread of noise. In addition, artificial noise barriers such as sound barriers and sound source isolation facilities can be built around buildings to further reduce the transmission of low-frequency noise.
In short, solving the problem of wall resonance noise and low-frequency noise requires a comprehensive consideration of a variety of factors, including the noise level, propagation route and isolation method. The problems of wall resonance noise and low-frequency noise can be effectively solved by finding the cause, sound insulation treatment, structural reinforcement, equipment replacement or adjustment, and external environment improvement.
