The air supply outlet in the corridor is so loud.

You can negotiate with the property and let the property solve it.

If the corridor is too noisy, you can try to find a property and let the property manager mediate. If there are too many people affected by the residents, they must unite to find a property, and the property will pay attention to it.

You can also build a floating sound insulation and damping layer in the room, which can effectively reduce the sound of ground impact and air echo. The thickness of the wall affects the sound insulation effect of the house. If the walls of the house are not thick enough, you can always hear the crying of the children upstairs and the voices in the corridor at your doorstep. The partition walls of many high-rise buildings are hollow walls, which greatly affects the sound insulation effect. Therefore, it is recommended to knock on the household wall by hand when buying a house. The echo of a solid wall is smaller, and the echo of a hollow wall will vibrate.
