I'm in the elevator on the fifth floor. Especially in winter, you can hear the whistling wind at night, and it will blow so hard in summer. It's scary. It's horrible. This is a matter of feng shui.

First of all, it's not a matter of feng shui, so don't worry.

Let's talk briefly about the reasons. This phenomenon is common in buildings with elevators, especially in almost every building in some cities in Northeast China. It's just a matter of wind power.

In winter, the temperature difference between indoor and outdoor is relatively large, so there will be a warm air flow in the building, and the outdoor air flow is the cold air flow. Because there is an open vent on the top floor of the elevator room, cold air and warm air will meet here to form convection. When the elevator is running, there will be a strong squeeze on the gas here, and there will be a loud sound, whirring or whining. This kind of sound can be heard by residents near the elevator, and can be heard by residents near the third floor of the ground floor and the third floor of the top floor. In addition, the elevators on the 20th floor or so will have redundant standby power supply, pump room and vent around the 10 floor, so that residents on the 10 floor will feel this way. Another reason is that the building is not flat, there are prominent balconies outside, or concave-convex angles made for beauty. When the wind is strong in winter, they will have a strong impact with these concave and convex parts, forming a sound similar to whistling or whining. When the summer wind is particularly strong, the reasons are similar. One is the gas in the elevator, the other is the problem of the building, and the other is the sound similar to whistle when the wind enters the top of the smoke exhaust pipe (the smoke exhaust pipe is semi-frozen in winter, so the wind will not make a sound), which can be heard by residents near the top floor. We can try to solve the problem of the elevator room by closing the door of the safe passage or adding foam strips on the door of the safe passage to make the door smaller and reduce the wind force. If it is the other two, there is no solution yet.
