Hearing is the ability to perceive sound through the ears. It involves the detection of sound waves, which are vibrations that travel through the air. When these sound waves reach the ear, they cause the eardrum to vibrate, and these vibrations are then converted into electrical signals that the brain interprets as sound. The process of hearing begins with the outer ear, which collects sound waves and directs them into the ear canal. The middle ear amplifies these vibrations, while the inner ear, specifically the cochlea, transforms them into signals for the auditory nerve. This nerve sends the information to the brain, allowing us to recognize and understand sounds.
