The buffer bend energy dissipation bend of the toilet sewer pipe is too noisy, how to reduce elim

The general treatment method is to wrap a layer of yellow glass wool or black insulation cotton, and seal the sound insulation board around it.

Now the ordinary noise prevention and control is mainly completed by low-density insulation cotton on the market, low-density and large particles, no stickiness can only be fixed with tape, adsorption and vibration damping, the reduction effect is very general, and there is little difference between package and non-package. It can't be fundamentally solved.

If we want to go to the next level on this basis, we must start from the source of noise, a new generation of low-frequency damping sheet will solve this problem very well, the vibration of the pipe wall is the main reason, the damping sheet + sound insulation cotton used together, it will greatly reduce the vibration of the pipe wall, thereby reducing the generation of noise, to achieve the maximum sound insulation effect.

Low-frequency damping sheet: It has strong viscosity and tensile properties, strong vibration and shock absorption performance to prevent the vibration of the object, stop the generation of noise from the source, and isolate the conduction of the object to the sound. In particular, it has a good absorption effect on low frequency and vibration noise.

Rubber and plastic soundproof cotton: It is a mixed foam material of nitrile rubber and polyvinyl chloride, because it is a closed-cell foam body, the sound from the pipe is repeatedly reflected and absorbed by the foam body in the middle in the closed space, so as to absorb high-frequency noise.

Bathroom soundproof door or affixed soundproof strip This is the design problem of the real estate developer, this kind of pipe should not be installed in this way, it is a unified large pipe installed outside, the indoor is a set of elbows, each floor of each set of residents to take out, they are connected, there are bricks outside, down the drain.

Personally, I think that you can only reduce this, eliminate this sound, but not stop it, you can get a water pipe package, so that it is beneficial to eliminate the sound.

There is something called soundproof cotton, you can try it.

This one is not easy to deal with because you are on the lower floor and there are more people upstairs!

You can choose to make a soundproof package to deal with it, and we are using this kind of pipe here.
