What's the experience of living in a house with poor sound insulation?

Very bad experience. I once had such an experience. A few years ago, there was a small factory that produced toilet paper next door. At midnight, it was the sound of the machine. Noisy people have headaches and can't sleep well. It's a feeling that sound will enter your nerves. After a long time, it is easy to be nervous, especially affecting sleep.

Another time, resting at home on weekends is really hard to get. I heard the sound of decoration upstairs, as if it were right above my head. It's really irritating. When I came back from going out with my children, I met a beautiful woman in the elevator and knocked at the door.

Later, I learned that she was a college student and studied at home these two days, but the noise from the upstairs decoration was really annoying, so I went out to look for it. Let's see which one is being renovated, and we'll find it together. We all thought it was our own upstairs, so we didn't find a few floors.

Therefore, living in a house with poor sound insulation is really a particularly painful feeling. There are also sounds coming from the middle of the night, people walking around the house in the dead of night or the sound of washing machines, which is really uncomfortable.
