The eardrum, also known as the tympanic membrane, is a thin, cone-shaped membrane located in the middle ear. It plays a crucial role in hearing by vibrating in response to sound waves. These vibrations are then transmitted to the tiny bones in the middle ear, known as the ossicles, which amplify the sound and send it to the inner ear. The eardrum is sensitive and can be affected by various factors, such as infections, injuries, or changes in pressure. Damage to the eardrum can lead to hearing loss or discomfort, making it important to protect this delicate structure from harm.
