The eardrum, also known as the tympanic membrane, is a thin, cone-shaped membrane located in the ear. It separates the outer ear from the middle ear and plays a crucial role in hearing. When sound waves enter the ear, they cause the eardrum to vibrate, which then transmits these vibrations to the tiny bones in the middle 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.
