Fan - Oscillating

This is the sound of an oscillating fan moving from side to side. Fans are often used in lieu of white noise machines due to their wide availability and low cost. The first recorded mechanical fan was the punkah fan used in the Middle East in the early 19th century. It had a canvas covered frame that was suspended from the ceiling. Servants, known as punkah wallahs, pulled a rope connected to the frame to move the fan back and forth.
