Online Hearing Test: Pure-Tone Audiometry & Audiogram

What it measures

Your hearing threshold — the quietest pure tone you can detect — at several pitches in each ear, plotted as an audiogram. The four speech frequencies (500–4000 Hz) are averaged into a pure-tone average (PTA) that estimates the degree of any hearing loss.

How it works

For each frequency a steady tone fades from clearly audible to silent. You press and hold for as long as you can still hear it; the point where it vanishes estimates your threshold for that pitch. Right and left ears are tested separately through your headphones using stereo panning.

Tips for an accurate result

• 1Calibrate honestly — Set the reference so it’s gentle, not loud. Over-driving the volume flatters every threshold.
• 2Test both ears — Asymmetry between ears is one of the most clinically important signs — always complete both sides.
• 3Re-test on another day — A single screening can be thrown off by earwax, a cold, or a noisy room. Trends matter more than one run.
• 4Protect what you have — Most preventable loss is noise-related. Use ear protection at concerts, with power tools, and at the gym.
