Hearing Loss Simulator
Compare an original spoken sentence with filtered versions illustrating reduced speech clarity.
Use a quiet room and headphones at a low, comfortable device volume. Never increase the volume to force yourself to hear a sound. Stop if you feel discomfort. Sudden hearing loss needs urgent medical assessment—not an online test.
When speech loses its detail.
Listen to the same sentence with progressively reduced high-frequency detail. These filters illustrate muffled speech—not an accurate recreation of an individual's hearing loss or clinical severity.
“The morning breeze moves through the trees. We are meeting our friends for lunch by the water.”
Frequently asked
Can this diagnose hearing loss?
No. Uncalibrated devices, headphones and listening environments affect what you hear. An audiologist can measure hearing thresholds and investigate symptoms.
What if my hearing changed suddenly?
Sudden hearing loss needs urgent medical assessment. Do not wait for an online result. New one-sided symptoms, dizziness, pain or drainage also need medical advice.
