* Vibrations create pressure waves: When an object vibrates, it pushes against the air (or other medium) around it. This creates areas of high pressure (where the air is compressed) and low pressure (where the air is less dense).
* Pressure waves travel: These alternating areas of high and low pressure travel outwards from the vibrating object.
* Our ears detect these waves: Our ears have a membrane called the eardrum that vibrates in response to these pressure waves. These vibrations are then translated into electrical signals by our brains, which we perceive as sound.
In summary: Sound is the result of vibrations in matter that create pressure waves that travel through a medium and are detected by our ears.
