Hearing Range Test (Hz Range Tester)

This hearing range test (Hz range tester) lets you sweep a tone across the full 20 Hz – 20 kHz audible range, test each ear on its own, and mark the lowest and highest pitches you can hear to see your personal frequency 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 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, and by 60–70 the upper limit often falls to 8–10 kHz. The high-frequency end is what this tool works best as a high frequency hearing test for, because that is where age-related and noise-related changes show up first. The low end matters less for everyday hearing and is usually limited by your speakers long before your ears. For context, speech intelligibility lives mostly in the 500 Hz–4 kHz band, so even a reduced high-frequency range doesn’t prevent conversation — but it does affect the perception of clarity, consonants like "s" and "f," and musical overtones.

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). If you want to generate a specific reference pitch to compare against this sweep, try the online tone generator which lets you hold any frequency steady at a precise level.

Why headphones, and why per-ear?

Hearing often differs between ears, and a left-right ear test can reveal that asymmetry — but only with headphones, since speakers send sound to both ears at once. Use the Left ear / Right ear buttons to route the tone to one side at a time. 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. In-ear monitors and over-ear headphones typically extend to 20 kHz and sometimes beyond; most laptop speakers roll off sharply above 10–12 kHz and below 150 Hz.

What this can’t do

A clinical hearing test measures your threshold (the quietest level you can detect at each frequency), performed with calibrated audiometric equipment in a sound-treated booth, and produces an audiogram. The audiogram maps hearing thresholds in decibels across octave and half-octave bands from 250 Hz to 8 kHz (and sometimes 16 kHz for extended high-frequency audiometry). 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 or your actual hearing thresholds. Treat the numbers as a bit of fun. If you notice hearing loss, ringing (tinnitus), or a noticeable difference between your ears, see an audiologist.

Frequently Asked Questions

What is a normal human hearing range?

The classic figure is 20 Hz to 20 kHz, but that’s an idealized young-adult range. Real ranges are usually narrower, especially at the top, and the high-frequency limit declines gradually with age. There’s no single "correct" range.

I can’t hear the very low or very high tones — is something wrong?

Usually not. Most speakers and headphones can’t reproduce below ~40–50 Hz or above ~16 kHz, so silence at the extremes is typically your equipment. Try good headphones at a moderate volume. This isn’t a medical test, so don’t draw conclusions from it.

How do I test each ear separately?

Put on headphones, then choose Left ear or Right ear before playing — the tone is panned fully to that side. Find your range on one side, then switch and compare. (Without headphones, both ears hear everything, so per-ear testing won’t work.)

Can this replace a real hearing test?

No. A clinical test measures how quiet a sound you can detect at each frequency with calibrated gear; this only shows a rough audible range with your own hardware and volume. If you’re worried about your hearing, see an audiologist.

Why does the low end sound buzzy or like clicks?

Very low frequencies are hard for small speakers to produce cleanly, so you may hear distortion, rattle, or the speaker "chuffing" rather than a pure tone. The tool fades the volume to avoid clicks when you change frequency, but it can’t fix what the speaker physically can’t reproduce.

Is the tone loud enough to be safe?

Keep the volume low — just loud enough to compare. Don’t crank it to chase a tone you can’t hear, especially on headphones; protect your hearing. The default volume is intentionally modest.

Is my result saved or sent anywhere?

Nothing is uploaded and the microphone is never used. If you save a result it’s stored only in your own browser so you can compare next time, and you can clear it any time with the Clear button.

How does high-frequency hearing change with age?

Age-related high-frequency hearing loss (presbycusis) is the most predictable pattern in audiology. A typical adult in their 20s may hear up to 18–20 kHz; by 40 that often drops to 14–16 kHz, and by 60 it can fall to 8–10 kHz. The decline is gradual and symmetrical in both ears when caused by age alone. However, noise exposure, genetics, and medication history all influence the rate — so individual results vary considerably. The comparison this tool shows is illustrative, not diagnostic.

Why might one ear hear higher frequencies than the other?

A consistent difference between ears — where one ear hears noticeably higher or shows a clearly different cutoff — can indicate asymmetric hearing loss, which has several possible causes: noise trauma (e.g., holding a phone to the same ear for years, firing a weapon), a history of ear infections on one side, or conditions like otosclerosis or Meniere’s disease. A one-time in-browser test is not a reliable way to diagnose this, but if you notice a substantial difference, it’s worth mentioning to an audiologist. You can also use the tinnitus frequency matcher to check whether you also notice a persistent ringing that differs between ears.

Can I use this to check whether I can hear ultrasonic pest repellers?

This tool sweeps up to 20 kHz, which is the conventional upper limit of human hearing. Ultrasonic pest repellers typically operate at 20–65 kHz — well above what this tool generates and above what any human can hear. You won’t be able to confirm your device is emitting sound using this test. The upper limit shown here tells you how far into the very high audible range your ears reach, not whether you can hear ultrasonic frequencies. For detecting ultrasonic emissions, see the ultrasonic frequency detector.
