How your ear works
Sound waves enter the ear canal and make the ear drum vibrate. This action moves the tiny chain of bones (ossicles – malleus, incus, stapes) in the middle ear. The last bone in this chain 'knocks' on the membrane window of the cochlea and makes the fluid in the cochlea move.

This video explains how the ear works. It describes how sound waves travel through the ear canal, vibrate the eardrum, move the chain of middle ear bones, and set the fluid in the cochlea in motion.
Key points
- Sound waves are described as entering the ear canal and making the eardrum vibrate
- The vibration is described as moving the tiny chain of bones in the middle ear, the malleus, incus and stapes
- The last bone in the chain is described as knocking on the membrane window of the cochlea
- That action is described as making the fluid in the cochlea move
Video Overview
This video presents “How your ear works” — Sound waves enter the ear canal and make the ear drum vibrate. This action moves the tiny chain of bones (ossicles – malleus, incus, stapes) in the middle ear. The last bone in this chain 'knocks' on the membrane window of the cochlea. Whether you are preparing for a procedure, studying the technique, or learning how a condition is assessed, the recording shows the process as it is performed in practice.
