What Your Hearing Test Results Tell You

A hearing test, also called an audiogram or audiological evaluation, measures how well you can hear sounds at different volumes and frequencies. When you receive your results, you're getting a visual representation of your hearing ability compared to what's considered typical for your age. Understanding these results helps you learn about your hearing and what might be happening if you experience difficulty hearing in everyday situations.

Your audiologist or hearing care professional creates a graph called an audiogram during testing. This graph has frequency (pitch) on the horizontal axis and loudness (decibels) on the vertical axis. The results show the quietest sounds you can hear at each frequency. Most human speech falls between 250 and 8000 Hertz (Hz), which is the frequency range your audiologist focuses on during standard testing. The decibel scale ranges from 0 dB (the quietest sound a person with normal hearing can detect) to 120 dB (a dangerously loud sound that can cause immediate hearing damage).

Two symbols typically appear on your audiogram: an X marks your left ear results, and an O marks your right ear results. These symbols show where each ear's hearing threshold falls. If the symbols appear near the top of the graph (closer to 0 dB), that ear has normal or near-normal hearing. Symbols lower on the graph indicate that ear needs louder sounds to detect them, suggesting some degree of hearing loss. The pattern of these symbols across different frequencies tells you whether your hearing loss is consistent across all pitches or affects certain frequencies more than others.

Practical Takeaway: Before your next hearing test, ask your audiologist to explain your specific results. Request a copy of your audiogram to keep for your records, and write down what your audiologist says about whether your hearing is normal, shows mild loss, moderate loss, or more significant loss.

Types of Hearing Loss and What They Mean

Hearing loss falls into three main categories based on where the problem occurs in your ear. Understanding which type you have helps explain why you might struggle with certain sounds or situations. Your audiologist determines the type through specific tests during your hearing evaluation.

Conductive hearing loss happens when sound cannot travel properly through your outer ear or middle ear. Common causes include earwax buildup, ear infections, fluid in the middle ear, problems with the eardrum, or issues with the tiny bones in the middle ear. This type of hearing loss often affects all frequencies similarly—it's like someone turned down the volume on everything you hear. The good news is that conductive hearing loss is frequently treatable through medical intervention or procedures. For example, removing earwax, treating an infection, or having tubes placed in the ear might restore normal hearing. On an audiogram, conductive hearing loss typically shows a particular pattern where bone conduction testing (how sound travels through skull vibration) shows better hearing than air conduction testing (how sound travels through the ear canal).

Sensorineural hearing loss occurs when the inner ear (cochlea) or the nerve pathway from the ear to the brain doesn't function properly. This is the most common type of hearing loss and accounts for about 90 percent of all hearing loss cases. Causes include aging, exposure to loud noise over time, genetics, certain medications, head injury, infections, or medical conditions. Sensorineural hearing loss is permanent because the tiny hair cells in the inner ear that convert sound waves to nerve signals cannot repair themselves once damaged. However, hearing aids and other devices can help you work with the hearing you have. This type often affects higher frequencies more than lower frequencies, which is why some people hear low voices better than high voices or why they struggle to hear women's and children's voices clearly.

Mixed hearing loss means you have both conductive and sensorineural components—parts of your hearing system have multiple problems. You might have permanent damage to your inner ear combined with a temporary middle ear issue. Treatment for mixed hearing loss addresses both components when possible.

Practical Takeaway: Write down which type of hearing loss your test shows. If it's conductive, ask whether treatment options exist. If it's sensorineural, ask about devices or technologies that could help you hear better.

Reading Your Audiogram: Understanding Thresholds and Patterns

Your audiogram contains specific information about your hearing at different pitches. Learning to read it yourself gives you better insight into your hearing situation. The numbers and symbols on the graph translate directly into what you might experience in daily life.

The vertical axis of your audiogram shows loudness in decibels (dB). The scale typically runs from 0 dB at the top to 120 dB at the bottom. Normal hearing falls between 0 and 20 dB. If your symbols appear in this range, you have normal hearing at those frequencies. A rating of 21 to 40 dB indicates mild hearing loss. At this level, you might miss some quiet sounds in conversation but generally manage without devices. Moderate hearing loss (41 to 60 dB) means you likely struggle to hear normal conversation without assistance. Moderately severe loss (61 to 80 dB) requires hearing aids for most daily communication. Severe loss (81 to 100 dB) means you might only hear very loud sounds or speech. Profound loss (above 100 dB) means you may not hear sound through air conduction at all.

The horizontal axis shows frequency in Hertz (Hz), ranging from low frequencies on the left (250 Hz) to high frequencies on the right (8000 Hz or higher). Different frequencies represent different pitches. Low frequencies include sounds like a man's voice, thunder, or bass notes in music. High frequencies include women's voices, children's voices, bird songs, and the "s" and "f" sounds in speech. The pattern your results make across frequencies matters significantly. Some people have relatively flat hearing loss, meaning the loss is similar across all frequencies. Others have sloping loss, where they hear low frequencies better than high frequencies. This pattern helps explain which sounds are hardest for you to hear.

Real-world example: A 65-year-old person with age-related hearing loss typically shows a pattern of normal-to-mild loss at low frequencies that gradually becomes moderate loss at high frequencies. This pattern means they might hear a door slam clearly but miss a doorbell chime, or hear their spouse's deep voice better than their spouse's spoken words if their spouse has a higher-pitched voice.

Practical Takeaway: Ask your audiologist to point out the specific frequencies where your hearing is worst. This information helps you understand which situations will be most challenging—high-frequency loss affects speech clarity more, while low-frequency loss might affect your ability to hear important warning sounds.

What Numbers and Decibels Mean in Everyday Situations

Understanding decibels helps you grasp how your hearing test results connect to real life. Decibels measure loudness on a scale where each increase of 10 dB represents a doubling in perceived loudness. Here's what typical sounds measure on the decibel scale: a whisper is around 30 dB, normal conversation is about 60 dB, a vacuum cleaner is around 70 dB, heavy traffic is about 85 dB, a lawn mower is 90 dB, and a rock concert is 110 dB or higher.

If your audiogram shows you need sounds at 40 dB to hear them at a particular frequency, that means normal conversation (60 dB) would be clearly audible at that frequency. However, if another frequency shows you need 60 dB to hear, you might miss quieter speech sounds even in conversation. This is where patterns matter. Someone with high-frequency hearing loss at 60 dB might hear their conversation partner just fine in a quiet room but struggle significantly in a noisy restaurant where higher-pitched voices compete with background noise.

Your hearing test also measures something called speech discrimination or speech recognition score. This percentage tells you how well you can understand words, even when you can hear them. You might be able to hear that someone is talking but struggle to understand the actual words. A score of 90 to 100 percent is excellent—you understand nearly all words you hear. Scores of 70 to 89 percent are good. Scores below 70 percent suggest you may have difficulty understanding speech even with proper volume, which might indicate a problem with how your inner ear processes sound or how your auditory nerve sends signals to your brain. This information is crucial because it means that simply turning up the volume might not solve your communication challenges.
