There is a factory nearby, why can the bedroom hear more clearly than the living room?

Because the living room is paved with floor tiles, that is, cement and yellow sand and floor tiles are poured on the ground, and the bedroom is just flat, and then plastic foam and flooring are paved, and the cement, yellow sand and floor tiles should be thicker than plastic foam and flooring, so although the ceiling is not made, the living room will be higher than the floor of the bedroom.

Because the bedroom is small and there is wind and sand by the window.

If there are many windows, it is easy to dissipate heat, and the temperature is low, and my room has the most windows, five windows, ventilated on three sides, and comfortable in summer, but this kind of low temperature weather suffers, like a refrigerator refrigerator. There are only two windows in the hall of my house, and now the temperature is 20 degrees, which is much warmer.

There will be a lot of water vapor in the kitchen, you agree with that.

For the convenience of sewage discharge.
