Hearing health often goes unnoticed until a problem arises, but an audiogram is a powerful tool in detecting and understanding hearing loss. Whether you’re experiencing hearing difficulties or simply want to monitor your auditory health, knowing how to read and interpret an audiogram is essential.
What is an Audiogram?
An audiogram is a graph that displays the results of a pure-tone hearing test, which measures how well you hear sounds at various frequencies (pitch) and intensities (loudness). It provides a visual representation of your hearing ability, helping audiologists diagnose the type and degree of hearing loss.
Key components of an audiogram:
- Frequencies (Hz): Displayed on the horizontal axis, ranging from low to high pitches — typically from 250 Hz to 8000 Hz.
- Decibels (dB): Shown on the vertical axis, indicating loudness levels — the higher the mark on the graph, the softer the sound you can hear.
- Symbols:
- O: Right ear air conduction
- X: Left ear air conduction
- [ and ]: Bone conduction scores
Why Are Audiograms Important?
Audiograms provide crucial information that goes beyond simply identifying whether you can hear. Here’s why they matter:
- Diagnosing Hearing Loss: Audiograms reveal the type of hearing loss you have:
- Conductive hearing loss: Often due to blockages or damage in the outer or middle ear.
- Sensorineural hearing loss: Stemming from inner ear or auditory nerve damage.
- Mixed hearing loss: A combination of both types.
- Tracking Progression: Regular audiograms help monitor changes in hearing over time. This is especially important for those exposed to loud environments or managing a progressive condition.
- Informing Treatment Options: Audiologists use audiograms to recommend tailored treatments like hearing aids, cochlear implants, or medical interventions.
- Establishing a Baseline: Healthy hearing adults can benefit from a baseline audiogram, allowing for future comparisons and early detection of hearing loss.
How to Read an Audiogram
Understanding your results can empower you to take charge of your hearing health. Here’s a quick guide:
- Normal hearing: 0 to 25 dB
- Mild hearing loss: 26 to 40 dB
- Moderate hearing loss: 41 to 55 dB
- Moderately severe hearing loss: 56 to 70 dB
- Severe hearing loss: 71 to 90 dB
- Profound hearing loss: 91+ dB
If you notice a drop in hearing at certain frequencies, it could indicate noise-induced hearing loss — often caused by prolonged exposure to loud sounds. Learn more about best hearing aids in background noise.
When Should You Get an Audiogram?
Consider scheduling an audiogram if you:
- Struggle to hear conversations, especially in noisy environments.
- Experience ringing or buzzing in your ears (tinnitus).
- Often ask people to repeat themselves.
- Notice a sudden change in hearing.
- Have a family history of hearing loss.
- Work in noisy environments.

Next Steps After an Audiogram
Following your audiogram, your audiologist will discuss personalized treatment options. These may include:
- Hearing aids: Modern devices now feature Bluetooth technology and AI enhancements. Explore how Bluetooth hearing aids work.
- Cochlear implants: Suitable for severe or profound hearing loss.
- Aural rehabilitation: Counseling and training to improve communication strategies.
Conclusion
An audiogram is more than just a chart — it’s a vital tool in preserving and improving your hearing health. Regular testing, combined with professional guidance, ensures you catch potential issues early and take proactive steps toward better hearing.
