In daily life, the ability to hear sounds allows us to communicate with our surroundings, be alerted to dangers, and engage with people. However, in some cases, hearing loss limits these abilities. The most effective ways to determine the cause and level of hearing loss are audiometry and tympanometry. In this article, we will explain these two main types of examinations in detail.
Causes of Hearing Problems
Hearing loss can occur for various reasons. These include:
- Genetic factors
- Prolonged exposure to loud sounds
- Aging
- Ear infections and inflammation
- Damage to the eardrum
- Accumulation of earwax
Who Should Have a Hearing Test?
If you experience the following symptoms, you should definitely undergo an examination:
- Frequently saying "what?" during conversations
- Listening to the TV at a high volume
- Not hearing the other person while talking on the phone
- Hearing speech unclearly or mixed up
What is Audiometry?
Audiometry is a test used to measure the level of hearing. This test determines which sounds a person can hear and how clearly they perceive these sounds.
How is Audiometry Conducted?
The test is conducted in a special soundproof room. The patient wears headphones, and sounds are played at different frequencies.
Pure-tone Audiometry
In this test, sounds are played at different frequencies and intensities. The patient presses a button when they hear the sound. This helps determine the hearing threshold.
Speech Audiometry
The patient is given various words and asked to repeat them. This measures how well they understand speech.
How are Audiometry Results Interpreted?
The results are displayed in a graph called an audiogram. The hearing level for each ear is indicated:
- Normal: 0-25 dB
- Mild loss: 26-40 dB
- Moderate: 41-55 dB
- Moderate-severe: 56-70 dB
- Severe: 71-90 dB
- Profound: 91 dB and above
When is Audiometry Recommended?
- When there are complaints about hearing
- When speech delay is observed in children
- Regularly in elderly individuals
- For individuals exposed to loud sounds at work
What is Tympanometry?
Tympanometry is a test that measures the pressure in the middle ear and the mobility of the eardrum. This test helps detect inflammation, fluid, swelling, or blockage of the auditory tube.
How is Tympanometry Conducted?
A small device is placed in the ear, and a pressure change is applied. The device measures the reaction of the eardrum.
What Do Tympanometry Results Mean?
- Type A — Normal result
- Type B — May indicate fluid or inflammation in the middle ear
- Type C — Indicates a problem with the function of the auditory tube
The Role of Tympanometry in Children
Tympanometry is very useful for children with adenoids, frequent ear infections, and speech problems. This test allows parents to intervene quickly and accurately when needed.
Differences Between Audiometry and Tympanometry
| Feature | Audiometry | Tympanometry |
|---|---|---|
| Measured Area | Hearing level | Middle ear function |
| Conducted by | Sounds played through headphones | Pressure applied to the ear |
| Result | Audiogram | Tympanogram |
| Purpose | Determine hearing loss | Detect middle ear pathologies |
Importance of Hearing Examination
Benefits of Early Diagnosis
Early detection of hearing loss improves the quality of life for both children and adults. Early treatment in children stimulates speech development, while in adults, it prevents social isolation and depression.
Referral for Treatment and Device Prescription
After diagnosis, a specialist may recommend a hearing aid. Especially, Bluetooth and water-resistant devices provide convenience in daily life.
How to Prepare for a Hearing Test?
Recommendations Before the Examination
- If you have earwax buildup, clean it beforehand
- Bring your previous hearing test results
- Stay calm and avoid panic before the test
