- You often ask people to repeat what they said.
- Friends or family tell you that you don't seem to hear very well.
- You don't laugh at jokes because you miss too much of the story
- You need to ask others about the details of a class or meeting you attended.
- People say that you play music or your TV too loudly.
- You can't hear the doorbell or telephone.
The doctor will do an ear exam and, if necessary, refer someone with these symptoms to an audiologist, a health professional who specializes in diagnosing and treating hearing problems. The audiologist will do various hearing tests that can help detect where the problem might be. For example, to test the function of the inner ear, the audiologist can put a special device behind the ear that transmits tones directly there. This helps to distinguish between inner ear and middle or outer ear problems. For other tests, the audiologist will use a small probe place at the entrance of the ear canal and record tiny responses from the cochlea.
A person may also need to see an otolaryngologist (pronounced: o-toe-lar-en-gah-luh-jist), a doctor who specializes in ear, nose, and throat problems.
