Hearing Range Test (Hz Range Tester)
Sweep a tone across the full 20 Hz – 20 kHz range, test each ear on its own, and mark the lowest and highest pitches you can hear to see your personal hearing range. The textbook young-adult range is 20 Hz to 20 kHz — most of us hear a narrower slice.
🔊 Use headphones at a low volume (essential for testing left and right ears separately). This is for fun and curiosity, not a calibrated audiogram or medical test. Most speakers and headphones can’t reproduce the extremes — below ~40–50 Hz or above ~16 kHz — so a tone you can’t hear is very often your equipment, not your ears. For any real concern about your hearing, see an audiologist.
Sweep & listen
Keep it low. To find a limit, sweep slowly until the tone just disappears, then mark it.
Your range
Sweep down until you can’t hear the tone and mark your lowest; sweep up until it vanishes and mark your highest. Switch ears and compare.
About Your Hearing Range
Human hearing is often quoted as 20 Hz to 20 kHz. That’s an idealized young-adult range — in practice the bottom end is hard to feel as a clear pitch and the top end drops steadily with age (a normal process called presbycusis). A teenager might hear close to 20 kHz; many adults over 50 top out around 12–14 kHz. The low end matters less for everyday hearing and is usually limited by your speakers long before your ears.
This tool lets you explore that range by ear: sweep the slider, and where the tone fades into silence is roughly your limit. Marking the lowest and highest points gives you a personal range and a rough age comparison based on the high end (which is the part that tracks age).
Why headphones, and why per-ear?
Hearing often differs between ears, and testing each one separately can reveal that — but only with headphones, since speakers send sound to both ears at once. Headphones also reproduce high and low frequencies far better than laptop or phone speakers, which roll off the extremes and will make you "fail" tones your ears could actually detect.
What this can’t do
A clinical hearing test measures your threshold (the quietest level you can detect) at each frequency, with calibrated equipment in a quiet room, and produces an audiogram. This tool uses uncalibrated tones at whatever volume and on whatever hardware you have, so it can only show a rough range, not your sensitivity. Treat the numbers as a bit of fun. If you notice hearing loss, ringing, or a difference between your ears that concerns you, see an audiologist.
