Review on Xiaomi Mijia Floor Fan (JLLDS01DM), white by Ewa Czubak ᠌

The actual motor is soundless. However, in this case the screw or propeller is eight since the stem is being beaten! Because of this, there is vibration in two planes, the entire body vibrates as a result, and most significantly, this screw vibration produces a throbbing low-frequency sound that sounds like a working electric locomotive shunting, which will be remembered by anybody who heard it at the station. After 15 minutes of it being on in silence, you can already walk in phase with it.
