What Happens In A Hearing Test

Hearing tests, also called audiometric tests, check how well you can hear sounds. Audiologists do these tests to find out if you have any hearing loss or other hearing problems. Understanding how a hearing test works can help you feel less worried. In addition, they can make sure your hearing health is checked accurately.

According to World Health Organization over 1.5 billion people, or nearly 20% of the population, live with some form of hearing loss. So in this guide, we will delve into the process of a hearing test. Let's start!

What Causes Hear Loss?

Hearing loss can be due to many factors, including:

1. Age: As people get older, they may experience age-related hearing loss, known as presbycusis.
2. Noise Exposure: Prolonged exposure to loud noises. These might be such as music, machinery, or firearms, can damage the hair cells in the inner ear, leading to hearing loss.
3. Genetics: Some forms of hearing loss can be inherited from one's parents.
4. Medical Conditions: Certain medical conditions, such as otosclerosis, Meniere's disease, and infections like meningitis or mumps, can cause hearing loss.
5. Medications: Some medications, such as certain antibiotics, chemotherapy drugs, and high doses of aspirin, can cause hearing loss.
6. Trauma: Head injuries or sudden changes in air pressure, such as those experienced during scuba diving or flying, can damage the ear and lead to hearing loss.
7. Earwax Buildup: Excessive earwax can block the ear canal and interfere with hearing.
8. Other Factors: Smoking, diabetes, and cardiovascular disease have also been linked to an increased risk of hearing loss.

Preparation for a Hearing Test

Before the test, it's important to inform the audiologist about any concerns or issues related to your hearing. Bring a list of medications you are taking and be prepared to discuss your medical history. It's also advisable to have a family member or friend accompany you to the appointment.

The Components of a Hearing Test

A typical hearing test usually takes around 30 minutes to an hour to complete. This test consists of several components, including:

1. Physical Examination: The audiologist may examine your ears using an otoscope to check for any visible issues.
2. Tympanometry: This test assesses the function of the middle ear and eardrum.
3. Pure-Tone Audiometry: You will wear headphones and respond to sounds of varying frequencies.
4. Speech Audiometry: This test evaluates your ability to hear and repeat words spoken at different volumes.
5. Bone Conduction Test: This test determines if hearing loss is due to issues in the inner ear or middle ear.
6. Otoacoustic Emissions (OAE) Test: This test measures the response of the inner ear to sound.

Interpreting the Hearing Test Results

After completing the hearing tests, the audiologist will use the results. Thus, they provide you a comprehensive understanding of your hearing health. Here's what you can expect during the interpretation:

1. Audiogram: You'll likely receive a printout called an audiogram, which is a graph depicting your hearing thresholds. The x-axis typically represents the sound frequency (pitch) in Hertz (Hz), ranging from low to high frequencies. The y-axis shows the sound intensity (loudness) in decibels (dB).

2. Threshold Levels: The audiologist will point out your hearing thresholds on the audiogram. These are the softest sounds you were able to hear at different frequencies during the test. The closer the line representing your thresholds is to the bottom of the graph (0 dB), the better your hearing for that frequency.

3. Interpretation of Hearing: Based on your thresholds and established guidelines, the audiologist will explain your hearing status. Here's a general breakdown: 

• Normal: Hearing thresholds fall within the normal range (typically -10 to 20 dB).
• Mild Hearing Loss: Thresholds are slightly elevated, indicating difficulty hearing some quiet sounds (around 20-40 dB).
• Moderate Hearing Loss: Conversation becomes more challenging, especially in noisy environments (around 40-60 dB).
• Moderately Severe Hearing Loss: Significant difficulty understanding speech without amplification (around 60-70 dB).
• Severe Hearing Loss: Difficulty understanding even loud speech (around 70-90 dB).
• Profound Hearing Loss: Very limited or no hearing ability (above 90 dB).

Countries with the Most Advanced Hearing Test

Some countries have advanced healthcare systems and specialized services, which means they likely have advanced hearing tests available:

• United States: They use advanced methods like electrophysiological testing and auditory brainstem response (ABR) testing.
• Germany: They use tools like otoacoustic emissions (OAE) testing and auditory evoked potential (AEP) testing.
• Japan: They use methods like high-frequency audiometry and tinnitus evaluation tools.
• Switzerland: They use techniques like extended high-frequency audiometry and real-ear measurement (REM) systems.
• Canada: They provide access to various tests like electrocochleography (ECoG) and auditory steady-state response (ASSR) testing.
