How does the process of hearing work, and why is it dependent on the ears?

The process of hearing involves sound waves entering the ear canal and reaching the eardrum, causing it to vibrate. These vibrations are then transmitted through the middle ear bones to the cochlea in the inner ear, where hair cells convert them into electrical signals that are sent to the brain for interpretation. This process is dependent on the ears because they are the organs that detect and transmit sound waves to the brain for processing.
