What Is an Audiogram — and Why Does It Matter?

An audiogram is a visual chart that maps your hearing ability across a range of frequencies and volumes. Produced after a professional hearing test, it plots how loud a sound needs to be — measured in decibels (dB) — before you can detect it at each frequency from low-pitched sounds (250 Hz) to high-pitched ones (8,000 Hz).

Audiologists, ENT specialists, schools, and employers all rely on audiograms to assess hearing health, diagnose conditions, and design treatment plans. Whether you’re managing age-related hearing loss, monitoring noise-induced damage, or supporting a child with hearing challenges, having a clear, printable audiogram is essential.

EarMart’s free online audiogram creator at earmart.in/generate-online-audiogram/ lets you plot, visualize, and print your audiogram in minutes — no software downloads, no sign-up, and no cost.

How to Plot Your Audiogram Online — Step by Step

Using EarMart’s audiogram plotter is quick and intuitive:

1. Open the tool — Visit earmart.in/generate-online-audiogram/ on any device.
2. Enter your hearing thresholds — Input the dB values provided in your hearing test report for each frequency (250 Hz, 500 Hz, 1000 Hz, 2000 Hz, 4000 Hz, 8000 Hz).
3. Select your ear — Choose left ear, right ear, or both.
4. Choose your plot type — Air conduction, bone conduction, or masked variants.
5. View your chart instantly — Your audiogram is rendered in real time.
6. Print or save as PDF — Download your audiogram to share with your audiologist, submit to a school, or keep for personal records.

No technical knowledge is needed. The entire process takes under five minutes.

Types of Audiogram Plots Supported

EarMart’s audiogram generator supports all four standard plot types used in clinical audiology:

Air Conduction (AC) — Right & Left Ear

Air conduction testing measures your overall hearing by delivering sounds through headphones or insert earphones. It reflects how well sound travels through the entire hearing pathway — outer ear, middle ear, and inner ear. The right ear is marked with an O and the left ear with an X on the chart.

Bone Conduction (BC) — Right & Left Ear

Bone conduction testing bypasses the outer and middle ear by vibrating a small device placed behind the ear. This directly stimulates the cochlea (inner ear), helping clinicians determine whether hearing loss is conductive, sensorineural, or mixed. Symbols used are < and [ for the right ear and > and ] for the left.

Air Conduction Masked

When one ear is significantly better than the other, masking noise is introduced into the non-test ear during air conduction testing. This prevents the better ear from “helping” and ensures results truly reflect the test ear. Masked AC results are plotted separately for accurate diagnosis.

Bone Conduction Masked

Masked bone conduction tests ensure that results represent the target ear only. These plots are critical in diagnosing the type and degree of hearing loss, and EarMart’s tool makes it easy to visualize both masked and unmasked bone conduction results side by side.

Understanding Audiogram Symbols

EarMart’s audiogram creator uses these standard clinical symbols and color-codes the left and right ears (blue for right, red for left — per international convention) so your chart is immediately readable by any audiologist worldwide.

What Can an Audiogram Reveal?

A well-plotted audiogram communicates far more than just “how well you hear.” The shape of the curve across frequencies indicates:

• High-frequency sloping loss — Common in noise-induced hearing loss and presbycusis (age-related hearing loss). High pitches are affected most.
• Flat loss — Even hearing reduction across all frequencies, often associated with certain medications or genetic conditions.
• Low-frequency loss — Less common; can be linked to Menière’s disease or endolymphatic hydrops.
• Cookie-bite loss — Mid-frequency dip, sometimes genetic in origin.
• Conductive vs. sensorineural loss — Identified by the gap (air-bone gap) between AC and BC thresholds. A significant gap indicates a conductive component that may be medically treatable.

Understanding your audiogram shape helps your audiologist recommend the most appropriate intervention — from hearing aids and assistive devices to surgery or medical treatment.

Who Should Use This Audiogram Tool?

Patients and individuals — Keep a personal record of your hearing over time. If you have multiple audiograms from different appointments, plotting them makes it easy to see whether your hearing has changed.

Audiologists and ENT clinics — Share this tool with patients for remote record-keeping, or use it as a quick teaching aid to explain hearing loss patterns during consultations.

Parents and educators — Children who have undergone school hearing screenings or clinical hearing tests deserve clear, documented results. Use EarMart’s tool to maintain accessible records and support school accommodation requests.

HR and occupational health teams — Workers in noisy environments often undergo periodic audiometric testing. This tool simplifies documentation and comparison over time.

Students and researchers — Generate standardised audiogram charts for case studies, academic reports, or research presentations.

Degrees of Hearing Loss — A Quick Reference

Audiograms are categorised into the following degrees of hearing loss based on average thresholds across key frequencies:

If your thresholds fall in the mild-to-moderate range, hearing aids are often recommended. The EarMart audiogram tool visually highlights where your results fall relative to normal hearing benchmarks, making it easier to understand and discuss your results.

Tips for Accurate Audiogram Plotting

• Use results from a professional test — Always enter thresholds from a test conducted by a certified audiologist using calibrated equipment.
• Match ear labels carefully — Double-check that you’re entering left-ear values for the left ear and right-ear values for the right ear.
• Include masked results when provided — If your audiologist performed masked testing, plot those values for the most clinically complete picture.
• Save your PDFs with dates — Label each downloaded audiogram with the test date so you can track changes over time.
• Bring printed audiograms to appointments — Many audiologists appreciate when patients arrive with their own records already organised.

Frequently Asked Questions

Is the EarMart audiogram creator really free?

Yes, completely. There are no charges, subscriptions, or in-app purchases.

Does EarMart store my hearing data?

No. All audiogram plotting is performed locally in your browser. EarMart does not collect or store any of your hearing test data.

Can I use this on my smartphone?

Absolutely. The tool is fully mobile-optimised and works on all modern browsers including Chrome, Safari, and Firefox on iOS and Android.

What file format is the download?

Your audiogram is downloadable as a PDF, which is universally accepted by healthcare providers, schools, and insurance companies.

Do I need a professional hearing test to use this tool?

Yes — you should always obtain your hearing thresholds from a certified audiologist. This tool is designed to visualise and print those results, not replace clinical testing.

Can I plot both ears on the same audiogram?

Yes. EarMart’s audiogram generator plots left and right ear data on the same chart using standard colour-coding and symbols, just like a clinical audiogram.

Is this tool suitable for children’s audiograms?

Yes. Parents and educators can use this tool to plot and print results from paediatric hearing screenings and clinical assessments.

The Importance of Regular Hearing Checks

The World Health Organization estimates that over 1.5 billion people globally live with some degree of hearing loss — and many are unaware of it. Early detection through routine hearing tests is the most effective way to prevent or limit long-term hearing-related challenges.

Just as regular eye tests are standard preventive care, annual or biennial hearing checks should be part of everyone’s health routine — especially for:

• Adults over 50
• People who work in loud environments
• Individuals with a family history of hearing loss
• Children with speech delays or frequent ear infections
• Anyone taking ototoxic medications (certain antibiotics, chemotherapy agents, or diuretics)

Once you have your results, EarMart’s audiogram creator helps you make sense of them and keep a clear, printable record.
