What Is an Audiogram? A Simple Guide to Understanding Your Hearing Test
If you’ve ever had a hearing test, your audiologist likely handed you a chart filled with lines, symbols, and numbers. That chart is called an audiogram — and it holds the key to understanding your hearing health.
An audiogram is a visual graph that plots how well you hear sounds across a range of frequencies (from low to high-pitched tones), separately for your left and right ears. The results help audiologists identify the type, degree, and configuration of hearing loss, guide treatment decisions, and monitor changes over time.
Now, with EarMart’s free online audiogram creator, you can plot, view, and print your own audiogram in minutes — right from your phone, tablet, or computer.
Why Plot Your Audiogram Online?
Whether you’re a patient, a parent, a student, or an audiologist, having a clear visual of hearing test results is invaluable. Here’s why thousands of users trust EarMart’s audiogram tool:
✅ Free to Use — Always
EarMart’s audiogram generator is completely free. No subscription, no hidden fees, and no signup required.
✅ Plot All Standard Audiogram Types
The tool supports every major audiogram plot type used in clinical audiology:
- Air Conduction (AC) – Tests overall hearing ability through headphones for both ears
- Bone Conduction (BC) – Assesses inner ear function via bone vibration to distinguish sensorineural from conductive hearing loss
- Air Conduction Masked – For accurate results when masking is applied to the non-test ear
- Bone Conduction Masked – Eliminates cross-hearing during bone conduction testing
Each plot uses standard audiogram symbols and color coding, making results easy to read and professional enough to share with your doctor.
✅ Print as PDF in One Click
Once your audiogram is plotted, download or print it as a PDF instantly. This is perfect for:
- Sharing with your audiologist or ENT doctor
- School documentation and university applications
- Medical record-keeping
- Remote consultations and telehealth appointments
✅ 100% Private — Your Data Stays With You
All audiogram plotting happens locally on your device. EarMart does not store, transmit, or share your hearing data. Your results are yours alone.
✅ Mobile-Optimized
Access the audiogram plotter from any device — smartphone, tablet, or desktop — without installing any app.
How to Use EarMart’s Online Audiogram Plotter
Getting your audiogram plotted takes just a few steps:
- Visit https://earmart.in/generate-online-audiogram/
- Enter your hearing thresholds (in dB HL) for each frequency, for both left and right ears
- Select the plot types you want to display: air conduction, bone conduction, masked, or unmasked
- View your audiogram instantly rendered as an interactive chart
- Print or download your audiogram as a PDF with one click
No technical knowledge required. The interface guides you step by step.
Understanding Audiogram Symbols
Audiograms use a standardized set of symbols recognized by audiologists worldwide. Here’s a quick reference:
| Symbol | Meaning |
|---|---|
| O | Right ear – air conduction (unmasked) |
| X | Left ear – air conduction (unmasked) |
| △ | Right ear – air conduction (masked) |
| □ | Left ear – air conduction (masked) |
| < | Right ear – bone conduction (unmasked) |
| > | Left ear – bone conduction (unmasked) |
| [ | Right ear – bone conduction (masked) |
| ] | Left ear – bone conduction (masked) |
EarMart’s tool plots all of these symbols clearly, using color-coding to differentiate left (blue) and right (red) ear results — just like a clinical audiogram.
What Can an Audiogram Tell You?
A well-plotted audiogram reveals much more than just “how well you hear.” It can indicate:
- The degree of hearing loss – Classified as normal, mild, moderate, moderately severe, severe, or profound
- The type of hearing loss – Conductive, sensorineural, or mixed
- The configuration – Flat, sloping, ski-slope, notched (e.g., noise-induced), or rising loss
- Speech understanding impact – Frequencies between 500 Hz and 4,000 Hz are critical for understanding speech
By comparing air conduction and bone conduction results on your audiogram, audiologists can determine whether hearing loss originates in the outer/middle ear or the inner ear — which directly affects treatment options.
Common Causes of Hearing Loss Visible on an Audiogram
Different causes of hearing loss leave recognizable patterns on an audiogram:
- Age-related hearing loss (presbycusis) – Gradual high-frequency loss, typically seen as a downward slope
- Noise-induced hearing loss – A characteristic notch at 4,000 Hz
- Conductive hearing loss – A gap between air conduction and bone conduction thresholds
- Otosclerosis or middle ear disease – Flat conductive loss pattern
- Sudden sensorineural hearing loss – Acute, often unilateral drop across frequencies
Having your audiogram plotted and printed allows you and your audiologist to identify these patterns quickly and begin appropriate intervention.

Tips for Getting the Most Accurate Audiogram
- Always use results from a certified audiologist or audiometric test — self-reported estimates are not clinically accurate
- Double-check which ear you’re entering data for at each frequency
- Use masked results when your audiologist applied masking during the test, to avoid cross-hearing errors
- Save your PDFs after each hearing test so you can compare audiograms over time
- Bring your printed audiogram to every hearing consultation for faster, more informed discussions
The Importance of Regular Hearing Tests
Hearing loss is often gradual — you may not notice it until significant damage has already occurred. The World Health Organization estimates over 1.5 billion people worldwide live with some degree of hearing loss, and many go undiagnosed for years.
Regular audiometric testing — and keeping a record of your audiograms — is one of the most effective ways to detect hearing changes early. Early intervention dramatically improves outcomes, whether through hearing aids, medical treatment, or hearing protection strategies.
Just as you schedule regular eye exams, make hearing checks a part of your routine healthcare.
