Detailed explanation-1: -The middle ear and inner ear change the vibrations to signals that the brain senses as sounds. A ruptured eardrum can’t vibrate as well as it should. This can cause a hearing problem, which often is temporary.
Detailed explanation-2: -A ruptured eardrum can result in hearing loss. It can also make the middle ear vulnerable to infections. A ruptured eardrum usually heals within a few weeks without treatment. But sometimes it requires a patch or surgical repair to heal.
Detailed explanation-3: -Aging and exposure to loud noise may cause wear and tear on the hairs or nerve cells in the cochlea that send sound signals to the brain. When these hairs or nerve cells are damaged or missing, electrical signals aren’t transmitted as efficiently, and hearing loss occurs.
Detailed explanation-4: -Tympanic membrane perforations can cause a conductive hearing loss (where the sound does not reach the inner ear). In general, the larger the hole, the larger the hearing loss. A hearing test (audiogram) can easily check how much hearing loss there is. Tympanic membrane perforations can cause ear infections.
