A lot of people leave a hearing test holding a piece of paper they do not fully understand.
The audiologist explains things quickly, points at a graph full of circles and lines, and suddenly starts talking about frequencies, decibels, and hearing thresholds.
Meanwhile, you are sitting there thinking:
“Wait… what exactly am I looking at?”
You are definitely not the only person who feels that way.
For something connected to everyday life, hearing test charts can look surprisingly technical at first.
But once someone explains the basics in plain English, audiograms become much easier to understand.
This guide breaks down how to read an audiogram, what common hearing test results actually mean, and how basic audiogram interpretation works without turning it into a giant medical lecture.
What Is an Audiogram?
An audiogram is basically a visual chart that shows how well someone hears different sounds.
It is created during a hearing test and helps audiologists measure hearing ability across different pitches and volumes.
The chart may look intimidating at first, but it is really just showing two main things:
- How high or low a sound is
- How loud a sound needs to be before you hear it
During the test, you usually wear headphones and respond whenever you hear tones.
Those responses get plotted onto the audiogram.
The final graph gives hearing specialists a clearer picture of your hearing patterns.
Why Hearing Test Results Look So Confusing
Honestly, part of the problem is that audiograms are designed for professionals.
Audiologists look at these charts every day.
Most patients do not.
So when people first see:
- Numbers across the top
- Numbers down the side
- Red and blue symbols
- Random lines and markings
it can feel more like reading a science graph than understanding your own hearing.
A lot of hearing clinics also move through explanations pretty quickly because they are used to the terminology.
That does not mean the information is impossible to understand.
It just means nobody usually explains it in simple language.
How to Read an Audiogram
The easiest way to understand how to read an audiogram is to break the chart into two parts.
Across the Top: Frequency
The numbers across the top represent frequency, measured in Hertz (Hz).
Frequency basically means pitch.
- Lower numbers = lower-pitched sounds
- Higher numbers = higher-pitched sounds
For example:
- Deep voices are lower frequency
- Birds chirping are higher frequency
- Children’s voices are often higher frequency too
Most speech happens somewhere in the middle ranges.
Down the Side: Volume
The numbers going down the side represent loudness, measured in decibels (dB).
This part sometimes confuses people because the chart works backward from what they expect.
Sounds near the top are softer.
Sounds lower on the graph are louder.
So if marks appear lower on the chart, it means louder sounds were needed before they became audible.
In simple terms:
The lower the symbols drop on the graph, the more hearing difficulty may exist.
Understanding Frequency and Pitch
Frequency matters because hearing loss does not always affect every sound equally.
Some people hear low pitches fairly well but struggle with higher frequencies.
That is actually very common.
High-frequency hearing loss often makes speech sound unclear rather than simply quiet.
People may say things like:
- “I can hear people talking, but I cannot understand them.”
- “Everyone sounds like they are mumbling.”
- “I miss parts of words.”
That happens because many speech details live in higher frequencies.
Consonants like:
- S
- F
- T
- SH
are often harder to hear first.
This is one reason hearing loss sometimes feels more frustrating in restaurants or crowded spaces.
Background noise competes with speech clarity.
Understanding Hearing Levels and Volume
Another important part of hearing test results is understanding hearing thresholds.
A hearing threshold is simply the quietest sound you can hear at a specific frequency.
Generally speaking:
- Marks near the top of the chart suggest better hearing
- Marks farther down suggest more hearing difficulty
Audiologists often categorize hearing levels like this:
- Normal hearing
- Mild hearing loss
- Moderate hearing loss
- Severe hearing loss
- Profound hearing loss
But hearing is not always experienced emotionally in neat categories.
Someone with “mild” hearing loss may still struggle constantly in noisy environments.
Meanwhile another person may barely notice changes at all.
The chart provides useful information, but daily life matters too.
What the Symbols on an Audiogram Mean
One of the first things people notice during audiogram interpretation is the strange symbols.
Most audiograms use:
- Red circles for the right ear
- Blue X symbols for the left ear
These symbols mark the softest sounds heard during testing.
You may also see:
- Dashed lines
- Triangles
- Brackets
- Bone conduction symbols
Those help audiologists compare how sound travels through different parts of the hearing system.
For example, some tests check whether sound problems involve:
- The outer or middle ear
- The inner ear
- Or the auditory nerve
That distinction helps identify different types of hearing loss.
Audiogram Interpretation Basics
When professionals discuss audiogram interpretation, they are usually looking for patterns.
They ask questions like:
- Is hearing loss mild or severe?
- Does it affect one ear or both?
- Are high frequencies worse than low frequencies?
- Is the hearing loss conductive or sensorineural?
- Did hearing change suddenly or gradually?
The shape of the graph can reveal a surprising amount.
For example:
Sloping Hearing Loss
A downward slope toward higher frequencies is very common with age-related hearing changes.
Flat Hearing Loss
A flat pattern means hearing levels stay fairly similar across frequencies.
One-Sided Hearing Loss
If one ear looks dramatically different, doctors may investigate further.
Patterns matter almost as much as the numbers themselves.
Different Types of Hearing Loss
An audiogram also helps identify the type of hearing loss someone may have.
Conductive Hearing Loss
This happens when sound has trouble moving through the outer or middle ear.
Common causes include:
- Earwax
- Ear infections
- Fluid buildup
- Eardrum problems
Conductive hearing loss is often treatable.
Sensorineural Hearing Loss
This involves the inner ear or hearing nerve.
Common causes include:
- Aging
- Loud noise exposure
- Genetics
- Certain illnesses
This type is usually permanent.
Mixed Hearing Loss
Some people experience both conductive and sensorineural hearing loss at the same time.
The audiogram helps doctors identify those combinations.
What Counts as Normal Hearing?
People often ask whether their hearing test results are “normal.”
Generally, hearing thresholds within the typical speech range are considered normal if sounds are heard at softer decibel levels.
But “normal hearing” is not always black and white.
Some people technically fall within normal ranges yet still struggle in noisy situations.
Others may notice hearing fatigue long before tests show major changes.
Hearing ability also changes naturally with age.
That is completely common.
The important thing is paying attention to noticeable changes rather than obsessing over a single number on a chart.
When to Follow Up After a Hearing Test
Sometimes hearing tests simply establish a baseline.
Other times, follow-up testing becomes important.
You should consider additional evaluation if you notice:
- Sudden hearing changes
- Persistent ringing in the ears
- Rapid worsening hearing
- One-sided hearing loss
- Difficulty understanding speech
- Dizziness or balance issues
Hearing problems often develop gradually, which is why many people do not realize how much things have changed until someone else points it out.
Getting hearing checked early can make a big difference.
Conclusion
At first glance, audiograms can look confusing and overly technical.
But once you understand the basics, they become much easier to read.
The main thing to remember is that an audiogram is simply showing:
- Which sounds you hear
- Which sounds you struggle to hear
- How loud sounds must be before you notice them
Learning how to read an audiogram can help you better understand your own hearing health, ask better questions during appointments, and feel less overwhelmed by medical terminology.
And honestly, that alone makes the chart feel a lot less intimidating.

An audiogram is a chart that shows how well a person hears different pitches and volumes.
How do you read hearing test results?
You read hearing test results by looking at frequency across the top of the chart and loudness down the side.
What do the symbols on an audiogram mean?
Red circles usually represent the right ear, while blue X symbols represent the left ear.
What is normal hearing on an audiogram?
Normal hearing generally means softer sounds can still be heard across common speech frequencies.
What is audiogram interpretation?
Audiogram interpretation involves analyzing hearing patterns, severity, and possible types of hearing loss.
Can an audiogram show hearing loss?
Yes. Audiograms help identify hearing loss severity and patterns.
Why do I hear people but not understand them?
This often happens with high-frequency hearing loss, where speech clarity becomes harder even if volume seems loud enough.
