Which season is the elevator noisier, summer or winter?

Because the air in winter is dry, it is drier than other seasons. This dry environment will cause the elevator chain to generate more static electricity, which will increase the noise. When the weather is cold in winter, elevator maintenance personnel will reduce the maintenance frequency or inspection intensity of elevators because of the cold weather. If the elevator is not repaired in time, the chain will be loose or damaged, resulting in greater noise.
