What Causes the ‘Rustle’ of a Forest in Autumn?

Imagine a forest where leaves are like tiny fans. In autumn, they start to move because of the wind and temperature changes. When they flutter or shake, they make a soft rustle that sounds like nature is whispering.

When it gets colder and the sun shines, leaves begin to fall from trees. They dance in the air as they drop, this movement makes the rustling sound you hear when you walk through a forest.
