Online Hearing Test

What this can and cannot tell you

This measures one thing: the upper edge of your hearing range. It is the part of hearing that fades first and fades predictably, which makes it a useful rough marker. It is not an audiogram and it cannot detect the losses that actually matter day to day.

Real hearing loss usually shows up first in the 2 to 4 kHz region, where consonants live. That is why someone can pass this test comfortably and still struggle to follow a conversation in a noisy room. A browser cannot test that region reliably, because it requires calibrated absolute volume, and no web page knows how loud your headphones actually are.

Treat a low result as a prompt to book a proper test, not as a diagnosis. Treat a high result as no evidence of anything at all.

Getting a result that means something

Use headphones, not laptop speakers. Most built-in speakers roll off sharply above 12 kHz and physically cannot reproduce the top of this range, so speakers will report your hardware limit as your hearing limit.

Set the volume to comfortable at the starting tone and then do not touch it. Raising the volume as the tone climbs lets you chase a frequency you would not otherwise hear, which makes the number meaningless.

Run it in a quiet room. Background noise masks quiet high tones long before it masks anything else.

Test each ear separately if you can. Asymmetry between the two ears is a more useful signal than the absolute number, and it is the finding most worth taking to a clinician.

Why the upper limit falls with age

The hair cells in the cochlea that respond to the highest frequencies sit closest to the entrance, so they take the full force of every sound that enters the ear. They are also not replaced. The result is presbycusis: a slow, one-directional narrowing of the upper range that begins in the late teens and continues for life.

As a rough guide, the upper limit falls by around 1 kHz every decade after twenty, though noise exposure moves it far more than age does. Regular exposure to loud music or machinery without protection can cost more in five years than ageing costs in thirty.

What a real hearing test involves

Pure-tone audiometry is the standard, and it looks nothing like this page. You sit in a sound-treated booth wearing calibrated headphones while tones are presented at a range of frequencies, usually 250 Hz to 8 kHz, one ear at a time. For each frequency the level is moved up and down until the quietest level you respond to is found. The result is a threshold in decibels at every tested frequency, plotted as an audiogram.

That is the crucial difference. This page finds the highest frequency you can hear at whatever volume your headphones happen to produce. An audiogram finds how quiet a sound can get before you stop hearing it, at each frequency separately, in absolute units. Only the second answers the question people actually care about, which is whether speech is getting through.

A full appointment usually adds bone conduction, which routes sound past the outer and middle ear. Comparing the two tells the clinician whether a loss is conductive, something blocking the path such as fluid or wax, or sensorineural, damage in the cochlea or the nerve. The first is often treatable and the second usually is not. No browser test can make that distinction.

Speech-in-noise testing is frequently added as well, because it is common to have a near-normal audiogram and still lose conversations in a busy room.

Asymmetry matters more than the number

The single most useful thing you can do with this page is run it twice, once per ear, with the other ear covered. Age-related loss is close to symmetric, so both ears usually cut off within a few hundred hertz of each other.

A clear gap between the two is a different finding. One-sided loss is not a normal ageing pattern, and it is on the short list of results worth taking to a clinician promptly rather than filing away. Sudden one-sided loss, especially over hours or days, is treated as urgent.

Because this test is uncalibrated, the absolute cutoff you get is partly a property of your headphones. The difference between your two ears is measured through the same headphones at the same volume, which is what makes it the more trustworthy number this page can give you.

What actually damages the top of your range

Noise exposure is cumulative and it is the largest modifiable factor by a wide margin. Damage tracks both level and duration together, so a short exposure at a very high level and a long exposure at a moderate one can cost the same. The cells that die do not come back.

The early sign is not silence. It is tinnitus after a loud event, or a few hours of muffled hearing that then recovers. That temporary shift is a warning that hair cells were stressed, and repeated warnings become permanent loss.

Personal audio at high volume through in-ear headphones is the common modern route, mostly because it is comfortable enough to sustain for hours. The practical rule is to lower the level until you can still hear someone speaking normally beside you, and to use protection at concerts and around machinery. Nothing on this page will show you the damage in the frequency range where it hurts you most, because that range is where a browser test is least reliable.
