What to Expect
-
Your audiologist may ask you:
- When your hearing difficulty began
- If it affects one ear or both ears
- If you hear ringing in your ears
- If you have ever had pain or discomfort in your ears
- If there has been any recent drainage from your ears
- If you have ever had ear infections
- If you have ever had an ear injury
- If you have ever had ear surgery
- If you ever have dizziness
- If there is a family history of hearing loss
- If you are exposed to a lot of noise at work
- If you often ask people to repeat themselves
- If others have commented that your television is too loud or that you speak too loudly
- If it is hard for you to understand a conversation when you are in a large group or a noisy place
-
If your child is being tested, the audiologist may ask about:
- Difficulties with speech and language development
- Other developmental issues
- Difficulty in school
- Health history
- Family history of permanent childhood hearing loss
- Your child’s responses to both familiar and unexpected sounds
-
Your audiologist will likely:
- Examine the outer ear for deformities
- Examine the ear canal and eardrum with an otoscope (a hand-held instrument that has a light and a magnifying lens)
There are several types of audiometry, including:
This test usually takes place in a soundproof booth. You will put on headphones that are connected to an audiometer. This device sends sounds of different volumes and pitches to one ear at a time. You will be asked to respond each time you hear a sound. You may be asked to respond by raising your hand.
You may also be asked to wear a special instrument called a bone oscillator. It is work behind each ear. The device sends sounds as vibrations directly to the inner ear. You will again be asked to respond each time you hear a sound.
Your test results are recorded on an audiogram. This is a chart or graph that shows the softest sounds you can hear. The audiologist will explain your test results.
