Is there any way to reduce noise?
There are three ways to reduce noise: one is to reduce noise at the sound source; The second is to reduce the noise in the process of sound transmission; The third is to reduce the noise at the human ear.

1. The best way to deal with noise is to close the window. Whether you have a single window or a double window, sealing is the most important thing. The bearing capacity of a barrel is determined by the shortest sawdust, and the sound insulation effect is determined by the weakest link.

2. It is also a simple way to use thick curtains to consume some sound energy, but it is certainly not a very effective way.

3. Install double curtains in the bedroom window and use thicker and denser floor curtains. When sleeping, closing the window and drawing double thick curtains can effectively reduce noise and absorb some noise.

4. Now some houses use light bricks (hollow bricks) as external walls, which have poor sealing performance. If your roadside has a great influence on you, you can also make a sandwich of wood square (light steel) and sound-absorbing (sound-insulating) cotton with gypsum board on the wall near the road, and then decorate the surface with wallpaper (of course, you can also treat the surface with ordinary wall paint).

Noise will affect human life.

Physical definition

Noise is the sound produced when the vocal body vibrates irregularly.

Physiological definition

Any sound that interferes with people's normal rest, study and work, as well as the sound that interferes with people's listening. In this sense, there are many sources of noise, such as the noise of cars in the street, the voices in the quiet library, the noise of machines on the construction site, and the loud noise of the neighbor's TV.
