Do you sometimes feel like you can't hear what your family is saying clearly? Do you need to turn up the volume on the TV more than usual? Or do you suspect that your little one is not responding to sounds properly? These are the things that make us think about whether we have a hearing problem. This is not something that only happens as we get older, it can happen to young children, young people, and anyone. So, the best thing to do at a time like this is to get an ear test, that is, a `(Hearing Test)`. Today, we will talk about what this is, how it is done, and whether there is anything to be afraid of.
Who should get this ear test?
Simply put, anyone who has even the slightest doubt about their hearing can get this test done. The medical name for this is ``Audiometry``. This is done by a hearing specialist ``Audiologist``. Usually, we go for an ear test in the following cases:
- For newborns: Before leaving the hospital, all babies are usually given a short hearing test (Newborn Hearing Screening). If the baby does not pass this, a more in-depth test will be performed. This allows for early detection of any problems and prompt treatment.
- For young children: If your child doesn't turn around when you speak, doesn't startle at sounds, or seems to be talking late for his age, your doctor may refer you for this type of test.
- For adults: This is the most common. If you have symptoms like not being able to understand what people are saying when talking to you, constantly asking them to "speak again," or turning the volume up on the TV or phone, it's time to get this test done.
There is nothing special you need to prepare for before these tests. And these tests do not hurt in any way. So there is no reason to be afraid.
What types of ear tests are there?
There are various tests to determine the type of hearing loss and how severe it is (mild, moderate, severe). Depending on your condition, your audiologist will decide which test you need. Let's take a look at the main types of tests that are performed.
| Name of the test | Simply put, what do you see in this? |
|---|---|
| Pure-tone testing | You're looking for the subtlest sound you can hear at different pitch levels. This is the most common test. |
| Bone conduction testing | The function of the fine hair cells in the inner ear, the cochlea, is tested. |
| Speech testing | We're seeing how well you can understand the words being spoken. |
| Auditory Brainstem Response (ABR) | It tests how your inner ear and brain work together. This is especially useful for young babies and those who have difficulty responding. |
| Otoacoustic Emissions (OAE) | This is a test to check if the inner ear is working properly. This is also a test often done on babies and young children. |
| Tympanometry | It measures how well your eardrum moves, which means the functioning of your middle ear. It can detect things like a perforated eardrum, fluid buildup, and blocked earwax. |
How do these tests work? Let's look at them one by one.
You've got a little idea about these tests. Now let's see what actually happens when each of these tests is performed.
Pure-tone testing
This is the test that most people know when they say "ear testing."
1. You will be taken to a completely soundproof room (sound-treated room).
2. You will be given something like headphones to wear.
3. Then, the audiologist uses an audiometer to play sounds like "t... t..." at different pitches and volumes.
4. All you have to do is raise your hand, press a button, or say "yes" when you hear the sound .
5. Based on your answers, the specialist will record them on a graph called an ``Audiogram.'' Finally, the graph will be used to determine your hearing level.
Bone conduction test
This sends sound directly to your inner ear.
- The specialist places a small device on the bone behind your ear or on your forehead.
- The device emits sound vibrations. The vibrations travel through your skull, bypassing the outer and middle ear, and directly into your inner ear.
- The results from this are compared with the results of the previous `Pure-tone` test to determine exactly what type of hearing loss you have.
Speech test
This tests how well you can recognize words.
- You are put on headphones, and the specialist says words at different volume levels.
- All you have to do is repeat the words you hear exactly as they are said .
- This measures the subtlest sound level and word recognition that you can hear and repeat clearly.
Remember, if there is anything you don't understand during any of these tests, don't be afraid to ask. The specialist will explain everything to you.
Auditory Brainstem Response (ABR)
This test is a little different. Unlike the others, you don't have to respond to sounds. You just have to stay calm and still.
1. You will be given earphones to wear.
2. Then, several small electrodes are attached to the skin of your scalp. These are connected to a computer.
3. These electrodes measure how your brain responds to sounds coming through the earphones (brainwave activity) and report it to the computer.
4. By looking at those reports, the specialist can understand how your auditory nerve and brain are connected.
Otoacoustic Emissions (OAE) test
This is also a very simple test that does not require a response.
- The specialist will insert a small earphone-like device into your ear.
- It sends a sound to the ear. A healthy ear produces a very subtle sound (called an `OAE`) in response to that sound.
- The device measures the subtle sound that comes back. If that sound doesn't come back, it means there may be a problem with the inner ear.
Tympanometry
This looks at your eardrum and middle ear.
1. A small probe is inserted into your ear. It feels like an earphone.
2. This device gently directs air pressure into your ear.
3. The way the eardrum responds to that pressure, that is, how it vibrates, is measured by a machine and recorded on a graph (Tympanogram).
4. If the eardrum is not moving properly, the cause could be fluid in the middle ear or a hole in the eardrum.
When will the results be available? What happens after that?
The best thing about these tests is that you don't have to wait long to get the results. The audiologist can tell you about your results almost immediately after the test is done . The graph that records the results is called an audiogram . It gives you a clear picture of the range of sounds you can hear.
Imagine that your hearing test reveals that you have some kind of hearing loss. Don't worry. The specialist will clearly explain what you need to do next.
- If you have a blockage in your ear, you will be referred to an ear, nose, and throat specialist (ENT - Otolaryngologist) to have it removed.
- It will explain whether your hearing loss is mild, moderate, or severe .
- It describes assistive devices that are suitable for that condition, such as hearing aids or cochlear implants.
- If you decide to use a hearing aid, they will select the one that best suits you, adjust it to fit your ear, and provide a fitting.
How often should I have an ear exam?
If you work in a very noisy environment, such as in the construction industry or a factory, it is very important to have your ears checked at least once a year .
Otherwise, for a normal person, this may not be necessary until they are 50-60 years old. For many people, age-related hearing loss begins at that time. However, age does not matter, if you feel a slight problem with your hearing, do not ignore it. See your family doctor as soon as possible and seek advice. If necessary, he or she will refer you to an audiologist.
There are now online tests that you can do at home. While these can give you a rough idea of whether you have a problem, they should not be relied upon. For an accurate diagnosis and proper advice, it is essential to see a qualified audiologist.
Take-Home Message
- Hearing is a very important part of our connection to the world. If you feel a little lacking in it, don't ignore it.
- A hearing test is a very simple, painless, and safe procedure.
- If you have any concerns about your child's hearing, getting it checked as soon as possible is essential for your child's speech and language development.
- Even if you get a basic idea from home tests, you should definitely see an audiologist for an accurate diagnosis.
- If you are diagnosed with hearing loss, there are many good solutions available today, such as hearing aids, to help you. So don't panic, talk to your doctor and choose the best solution.
