There is an electric sound on the top floor.

The top floor is mainly the sound of the elevator.

The low-frequency noise heard during operation should be the sound made when the elevator wheel rotates or rubs against the wire rope, which is generally "buzzing" and the like. This sound has a lot to do with the rated speed of elevators, such as the 8-meter speed ladder in the factory, which makes the wheels turn louder.
