Sound always originates as a vibrating object, whether a violin string, vocal chords, or a hanging leaf. The sound is carried to you by oscillating air molecules, which in turn set your eardrum vibrating.There are several ways in which wind makes itself heard.

On a windy day, a hodgepodge of sounds can be heard outside. Some of the sound is like whistling sound, some sound is like small objects falling / rolling and some sound is like objects rubbing into each other. There are three main contributions to the sound. Each of these is discussed below:
1. Friction- Friction occurs when objects rub over each other. When the air speed increases, the friction over objects increases also. The process of friction can release sound especially as wind speed becomes very high. The friction between air and objects can produce whistling sounds and swooshing sounds.
2. Falling / rolling objects- At higher wind speeds objects are more inclined to fall off of trees and buildings. These objects falling to the ground and rolling along the ground will create sound.
3. Object rubbing- When the wind increases, objects hit up against each other more. This is especially true for vegetation. Higher wind blows trees stems and leaves around more causing them to bump into each other and to create sound.
On a windy day, close your eyes and listen to all the sound. Try to pick out in your mind what is creating each individual sound.

Sound is created by objects/forces creating expansion and compression waves.
Wind is the movement of air molecules from one region to another, these molecules all impact each other and objects in it's path.
Wind also creates vibrations in your ear by rushing past it and exciting the hairs in your ear and your ear drum.
Hope this helps
These all create sound, th

The molecules of Air because sound travels by the vibration of air molecules.
