Pitch Test
This test is for entertainment, not medical screening, diagnosis, or treatment advice.
This test measures how small a difference in pitch your ears can detect. You will hear two short tones, one after the other, both near 440Hz, the note orchestras tune to. One is slightly higher.
Your job is to say which tone was higher. Each time you are right, the gap between the two shrinks, so it gets harder. Your score is the smallest gap, in hertz, you could still tell apart.

What the pitch test measures
This test measures your frequency discrimination, the smallest change in pitch you can reliably notice. Hearing scientists call this the frequency difference limen, and it is one of the oldest measures in psychoacoustics. Moore (1973) mapped how it behaves across the range of human hearing and showed that the ear is remarkably precise in the middle of that range, exactly where this test sits. We anchor both tones near 440Hz, the A that orchestras tune to, because the ear is close to its best there. The test is not asking whether you can hear a sound; it is asking how finely you can compare two sounds that are almost the same. That is a sharper question. Two people with equally good hearing on a standard audiogram can still differ a lot in how small a gap they can resolve, because the skill depends on how cleanly the brain reads the signal the ear sends, not just on whether the sound gets through.
How your ear tells two pitches apart
Inside the cochlea, a coiled tube in the inner ear, sits the basilar membrane. It is tuned along its length: high frequencies peak near the entrance, low frequencies deep inside, so each pitch lights up its own place. This place coding gives a first, rough estimate of frequency. But place alone is too blunt to explain how finely we hear, so the ear uses a second trick. Hair cells fire in step with the sound wave, a process called phase locking, so the timing of the nerve spikes carries the frequency directly. Sek and Moore (1995) showed that for tones up to a few thousand hertz this temporal code dominates fine pitch judgement, which is why discrimination is so sharp at 440Hz and falls apart higher up, where phase locking fades. When you compare two tones, your brain reads both codes, place and timing, and decides which signal sat higher. A small difference asks it to split a very fine hair, and how well it manages that is what this test scores.
Which factors affect it
The biggest swing usually comes from your gear and your room, not your ears. Headphones beat speakers, a quiet room beats a noisy one, and a sensible volume beats a faint one, because every bit of background noise or speaker colouring blurs the comparison. Musical training is the next big factor: people who tune instruments or sing in tune resolve smaller gaps, a difference Kishon- Rabin and colleagues (2001) measured directly between musicians and non-musicians. Age matters too, though less than you might think at this frequency, since age-related loss bites hardest far above 440Hz. Finally, practice counts: frequency discrimination is highly trainable, so a few honest attempts often beat a cold first try. Take the test on the same setup each time if you want to compare your own results fairly.
What your score means
Your score is the smallest gap, in hertz, you could still tell apart near 440Hz, so a lower number is a finer ear. Read these bands as approximate tiers drawn from the literature, not exact population percentiles, which do not exist for this skill in a clean form.
- Under 1Hz is exceptional, the range of professional musicians and trained ears. Resolving a gap this fine takes both good hearing and a lot of practice.
- 1 to 3Hz is very good, typical of a healthy young adult who listens carefully, and common among people with some musical background.
- 3 to 5Hz is the typical, average range for an adult on consumer gear in an ordinary room. Most people land here.
- 5 to 10Hz is below average for this task. It often points to speakers instead of headphones, a noisy room, or a low volume rather than anything about your ears.
- Over 10Hz usually says more about the setup than the listener. Headphone or speaker quality, background noise, a low volume, or a phone left on silent will all push the number up here, and a noisy browser test can score poorly even for someone whose hearing is completely normal. It tells you little on its own; try again on headphones in a quiet room.
The tiers come from the frequency discrimination literature (Moore 1973; Sek and Moore 1995; Kishon-Rabin and colleagues 2001), framed as approximate ranges rather than precise percentiles. A single run is only a snapshot, shaped by your gear, the room, and your focus, so keep your honest best rather than a distracted first attempt.
Questions
Should I use headphones or speakers?
Headphones are better for this test. They sit closer to the eardrum, cut out room reflections, and keep the level even across both tones, which is exactly what fine pitch judgement needs. Laptop and phone speakers are usable, but they roll off in the bass, add their own resonances, and let the room interfere, so the same ears often post a slightly coarser threshold through speakers than through a decent pair of headphones. If you do use speakers, sit close and keep the room quiet before trusting the number.
Are musicians really better at this?
On average, yes, and the gap is well documented. Kishon-Rabin and colleagues (2001) compared musicians and non-musicians and found musicians could resolve clearly smaller frequency differences, with trained ears often reaching well below one hertz around this range. The reason is practice, not a different ear. Years of tuning instruments, matching intervals, and listening critically sharpen the brain's reading of the signal the cochlea sends. You do not need to be a professional to do well, but if you tune a guitar by ear, expect a finer threshold than someone who never does.
How does pitch discrimination change with age?
It tends to get a little coarser with age, but more gently than people fear. The high-frequency hearing loss that comes with age (presbycusis) mostly affects sounds far above 440Hz, so a midrange pitch test like this one is fairly forgiving. What does change is the fine temporal processing the brain uses to lock onto a frequency, which slows slightly over the decades. A trained older listener will still beat an untrained young one, because practice matters more here than age does.
Will this work on my iPhone in silent mode?
No. The hardware mute switch on the side of an iPhone silences web audio, and there is no reliable way for a web page to get around it. If you hear nothing, flip the side switch off, turn the volume up with the buttons, and use the sound check on the start screen to confirm you can hear the reference tone before the scored part begins. The same applies to any phone left on silent or with media volume turned down. The pre-check exists precisely so a muted device does not turn into a bad score.
Does pitch discrimination improve with practice?
Yes, and faster than most people expect. Frequency discrimination is one of the most trainable hearing skills: even a few focused sessions measurably shrink the smallest gap a listener can detect, which is why ear-training apps work. The improvement is real but bounded, so do not expect to drop from ten hertz to half a hertz overnight. Run the test a few times and you will likely see your honest threshold settle a notch lower.
Can this test diagnose hearing loss?
No. This is a fun benchmark, not a medical screen. It checks one narrow skill, telling two midrange tones apart, on whatever device and in whatever room you happen to be in. A noisy cafe, cheap earbuds, a phone on low volume, or a switch left on silent can all produce a poor score in someone whose hearing is perfectly fine. A genuine hearing test uses calibrated equipment in a quiet booth. If you are worried about your hearing, see an audiologist; do not read anything medical into a browser game.
