Why can you hear the noise of the water pump on the fourth floor?

If the owner of the water pump supplies water to the owner of the community, because the floors of high-rise residential buildings are relatively high, the water pump is needed to supply water under pressure. Once the water consumption peak (such as summer night), the noise of the pump room will be particularly serious, which will affect the life and rest of the nearby owners. Usually the fourth floor is close to the house, so the noise of the pump can be heard on the fourth floor.

How to reduce and avoid noise

1, choose a good floor

In order to avoid noise, buyers should try not to choose the top floor or the first floor. There is an elevator room on the top floor. When the elevator is open, the vibration of the elevator will be transmitted through the floor. There are pits in the elevator on the first floor, and there are also cases where the noise from the elevator pit on the first floor disturbs people. In addition, low-rise houses are easily influenced by footsteps, voices and the closing sound of unit doors.

2. Pay attention to the community green belt.

Many people know that green belts can reduce traffic noise. Therefore, when choosing a house, we should pay more attention to the green belt of the community, not to see whether it can meet the sound insulation effect to the outside world, but also to see whether the distribution between the green belt and the building is reasonable and satisfactory, because if the building is not closed and dense, it will not form an echo space, and the natural noise will be weakened.

3. Choose a community far from the main road.

Now many developers promote the selling point of real estate is the good location of the house, close to the main road and so on. This type of community is really convenient for living and traveling, but such communities are often accompanied by noise problems. Property buyers should keep a proper distance from the noise source when choosing a house, and it is the main road, which needs special attention. The low-frequency noise emitted by cars on the main road is very penetrating, and people are very sensitive to this low-frequency noise. Ordinary windows can't isolate similar noise at all. So try not to choose a house that is too close to the street and business circle.

The thicker the wall, the better.

Generally speaking, the thicker the wall, the better the sound insulation effect. If the walls of the house are not thick enough, you can always hear the sound of flushing the toilet upstairs, the crying of the children next door, and the voices in the corridor at home. The partition walls of many high-rise buildings are hollow walls, which greatly affects the sound insulation effect. Bian Xiao suggested that buyers can knock on the tenants' walls by hand when choosing a house. If it is a solid wall, the echo will be less. If it is a hollow wall, the echo will be loud and it will vibrate.

5. Consider the glass factor.

Property buyers should choose flat double glass when choosing windows. Early residential windows were all push-pull plastic-steel windows, with large gaps, poor sealing and poor sound insulation. Nowadays, laminated glass is mostly used, which has the functions of sound insulation, ultraviolet protection, heat preservation and energy saving. The important point is that it can be used as an anti-theft net, which is not only strong, but also can prevent the impactor from penetrating even if it is violently hit by external force.
