Audiogram 101: Your Essential Guide to Understanding Hearing Tests
Unveiling the Audiogram
An audiogram is more than just a graph; it’s a map of your hearing health. This painless test, conducted by an audiologist, evaluates how well you hear sounds at different pitches. Understanding how an audiogram works can help you take better care of your hearing.

Understanding the Audiogram
Breaking Down the Axes
To comprehend an audiogram, you first need to understand its axes.
- Frequency (X-Axis): This horizontal axis represents sound pitch, measured in Hertz (Hz). It ranges from low-frequency sounds (125 Hz) to high-frequency sounds (8000 Hz).
- Intensity (Y-Axis): The vertical axis shows sound loudness, measured in decibels (dB), from -10 dB (very soft) to 110 dB (very loud).
These axes help plot your hearing thresholds across different pitches and volumes.
Decoding the Lines
The lines on your audiogram provide crucial information about your hearing capabilities.
- Hearing Threshold: These lines indicate the softest sound you can hear consistently at each pitch.
- Normal Hearing Range: Ideally, the lines should stay within the shaded area, indicating normal hearing.
- Hearing Loss Indicators: Lines dipping below this range suggest hearing loss, with severity based on how far they fall.
By examining these lines, you can see how well you hear across different frequencies.
Additional Components
Several additional components provide further insights into your hearing health.
Air vs. Bone Conduction: Two lines may appear, one for air conduction (standard method) and another for bone conduction (differentiating conductive vs. sensorineural loss).
These components help differentiate types of hearing loss and pinpoint specific issues.
What Your Audiogram Reveals
Degrees of Hearing Loss
Your audiogram can show various degrees of hearing loss, each impacting your hearing differently.
- Mild: 20-40 dB. Difficulty hearing faint sounds or understanding soft speech.
- Moderate: 40-60 dB. Challenges with conversations, especially in noisy environments.
- Severe: 60-90 dB. Speech sounds muffled; significant conversation difficulties.
- Profound: Over 90 dB. Reliance on visual cues or assistive devices.
Understanding these degrees helps in addressing your specific hearing challenges.
Types of Hearing Loss
Audiograms can also indicate different types of hearing loss.
- Conductive: Issues in the outer/middle ear obstruct sound waves. On the audiogram, look for a flat dip and air-bone gap.
- Sensorineural: Damage to the inner ear/auditory nerve. Variable dips with similar air and bone conduction thresholds.
Knowing the type of hearing loss helps in determining the proper treatment approach.
Diving Deeper: Conductive vs. Sensorineural Loss
Conductive Hearing Loss
Conductive hearing loss occurs when sound waves can’t travel efficiently through the outer or middle ear.
- Causes: Earwax buildup, infections, eardrum issues.
- Audiogram Clues: Air-bone gap and flat dip across frequencies.
- Treatment: Earwax removal, medication, surgery.
These indicators and treatments help restore sound transmission to the inner ear.
Sensorineural Hearing Loss
Sensorineural hearing loss involves damage to the inner ear or auditory nerve.
- Causes: Age, noise exposure, genetics.
- Audiogram Clues: Variable dips, similar air, and bone conduction thresholds.
- Treatment: Hearing aids, and cochlear implants.
Identifying these clues helps manage and treat this type of hearing loss effectively.
The Cost of an Audiogram
Understanding the cost of an audiogram can help you plan for this essential test. Audiogram costs vary by location, facility, and type.
There are ways to manage the cost of an audiogram effectively.
- Free Screenings: Some centers, like Stanford Hearing, offer free initial evaluations.
- Insurance: Check if your plan covers audiograms.

Exploring these options can reduce your out-of-pocket expenses.
The Role of the Audiologist
An audiogram is a crucial tool, but an audiologist’s expertise is vital for a complete evaluation. Audiologists consider your medical history and lifestyle alongside the audiogram for a comprehensive assessment. They explain your audiogram, pinpoint hearing loss, and suggest tailored solutions like hearing aids.
Regular monitoring and adjustments by your audiologist ensure ongoing hearing health.
