Do your ears hear equally? Most people have a subtle imbalance and don't even know it.
This free ear balance test plays tones through stereo panning and asks you to center the sound in your head. Your adjustments reveal whether one ear is stronger than the other —across five different frequencies.
Put on your headphones —this test requires stereo audio to work. It takes about 60 seconds.
Adjust your volume until this centered tone is clearly audible but comfortable.
A 1,000 Hz reference tone plays in the center of your headphones. Adjust your volume until it's comfortable and clearly audible.
In each round, a tone plays with a hidden stereo offset —slightly shifted left or right. You drag a slider until it sounds perfectly centered in your head.
The test runs at 250 Hz, 1 kHz, 4 kHz, 8 kHz, and 12 kHz. Different frequencies reveal different aspects of your ear balance since imbalance is often frequency-dependent.
Your centering accuracy across all five rounds produces a Balance Score from 0 to 100. A per-frequency chart shows exactly where any asymmetry exists.
The clinical concept behind this test is called the Interaural Level Difference (ILD) —the difference in perceived loudness between your two ears. In audiology, the Alternate Binaural Loudness Balance (ABLB) test is used to detect unilateral hearing loss.
Your brain constantly compares signals from both ears to locate sounds in space. When one ear is weaker —due to age, noise damage, ear infection, or wax buildup —the brain compensates, and you may not notice the imbalance in daily life. But a controlled stereo test reveals it.
The head shadow effect means high-frequency sounds (above ~1,500 Hz) are blocked more by your skull, so asymmetry tends to show up more at higher frequencies. That's why this test covers a range from deep bass (250 Hz) to treble (12,000 Hz).
This test uses stereo panning —shifting sound between your left and right ears. Speakers project sound into a room where both ears hear both channels, making the test meaningless. Headphones deliver isolated audio to each ear, which is essential for measuring balance.
A score below 70 suggests a noticeable difference between your ears. This could be caused by earwax buildup, an ear infection, headphone fit, noise-induced hearing loss, or natural asymmetry. If the imbalance is persistent and not caused by your headphones, consider seeing an audiologist.
Yes —significantly. Earwax buildup in one ear can reduce perceived loudness by 10-15 dB, which will show as a strong imbalance. If your results seem off, check for earwax or try the test after cleaning your ears.
Absolutely. Very few people have perfectly symmetrical hearing. A slight bias (score 80-95) is completely normal. The brain compensates for minor differences automatically. Only significant or sudden asymmetry warrants attention.
Hearing loss is rarely uniform across all frequencies. You might have perfect balance at 1 kHz but significant imbalance at 8 kHz. Testing across five frequencies creates a fuller picture of your ear symmetry, since the head shadow effect impacts high frequencies more than low ones.
The Hearing Age Test measures how high a frequency you can hear (both ears together). This Ear Balance Test measures whether your two ears hear the same frequencies at equal loudness. They test different things —try both!
Yes. If one headphone driver is louder than the other —common with cheap or damaged headphones —the test will detect headphone imbalance, not ear imbalance. Use headphones you trust are working evenly, or try a different pair to confirm results.
