EQ Ear Training Game

An EQ ear training game: the page plays you a sine tone, a sweep, or two tones in a row, and the job is to put a number on what you heard. Five frequency training modes go from naming a single tone up to hearing which of two tones is higher when they sit half a semitone apart. Every tone and answer stays inside a frequency range you set, so a tone above your hearing or below your speakers never costs you a point. Stats stick around between visits, and a heatmap shows you which band is currently your weakest.

Choose a training mode

Your frequency range

Every tone and every answer stays inside this range. Play both ends at a comfortable volume. If one is silent, move it in instead of turning the volume up, which would make the tones in between too loud. The widest range is 20 Hz to 20 kHz.

Why train your hearing?

Mixers don't have magic ears

What they actually do is sit in front of a parametric EQ for years, sweeping a narrow bell up and down a track until they can do it without looking at the screen. After enough hours of that, certain numbers go from being numbers into something close to a sensation. You hear a frequency and your brain hands you the number before you have thought about it. No genetic shortcut, no mystery. Just reps with feedback, which is the part this page is here to provide.

The payoff lands the first time you put on a new pair of headphones and a 250 Hz dip jumps out on its own. Reviews stop hand-waving. Buying decisions stop being "I think this one sounds nicer." Words about audio start lining up with measurements other people publish about audio, which is the only common language honest comparison can happen in.

About the range

Healthy young hearing reaches roughly 20 Hz at the bottom and 20 kHz at the top. That ceiling drops with age and with cumulative loud exposure. Most people in their 40s have already lost the top octave, and by 60 the lid sits closer to 12 kHz. The range setting above the modes goes up to 20 kHz partly so you can find where your own ceiling sits, partly so you can put a teenager on the same chair and feel ancient about it. It starts narrower, at 100 Hz to 12.5 kHz, because a tone you cannot hear teaches you nothing, and small laptop and phone speakers play little below 100 Hz anyway.

Different parts of the spectrum do different work in a track. The lowest octave is closer to vibration than to tone unless your room can actually move air at those wavelengths. Voice and most melodic content live somewhere between 200 Hz and 5 kHz, and a small dip in there is what gives recordings the "distant" quality reviewers complain about. Up above 12 kHz is the air band. Lose it and a recording feels flat across the board rather than missing any one element.

Frequency chart: what each band sounds like

Every review complaint - boomy, thin, shouty, honky, harsh, airy - sits in a specific band on the chart below. Once the band names live in your head, EQ graphs read like sentences, and a phrase like "3 dB peak around 3 kHz" lands on an actual ruler rather than a feeling.

RangeBand nameWhat lives there / what it sounds like
20-60 HzSub-bassFelt more than heard. Pipe organ pedals, kick drum body, EDM sub.
60-200 HzBassBass guitar fundamentals, drum body. Excess = boomy / one-note bass.
200-500 HzLower midrangeMale vocal weight, body of cellos and acoustic guitars. Excess = muddy / boxy.
500 Hz-2 kHzMidrangeVocal intelligibility, lead instruments. Most musical information lives here.
2-4 kHzUpper midrange / "presence"Where ear sensitivity peaks. Excess = forward / shouty / fatiguing.
4-8 kHzLower trebleString bow texture, cymbal stick attack. Where reviews call gear "bright."
6-10 kHzSibilance band"S" and "T" consonants. Tuning here makes or breaks vocal listenability.
10-16 kHzUpper treble / "air"Cymbal shimmer, room ambience, breath noise.
16 kHz+Extended trebleMost adults stop hearing here. Affects perceived "openness" more than detail.

Why frequency recognition is a learnable skill

People rarely disagree about whether a change happened; they disagree about where it happened. Naming the band is a trained skill, and it is trained the same way as any other perceptual skill - by repeated exposure with immediate, correct feedback.

The useful landmarks are broad. Under about 100 Hz is weight and rumble; 200 to 400 Hz carries warmth and, in excess, boxiness; 1 to 4 kHz is where presence and hardness live because it is where hearing is most sensitive; 6 to 10 kHz is sibilance and detail; above 12 kHz is air. Learning those five regions gets you most of the way.

That matters practically because it turns a vague reaction into an action. "Something is off" is not fixable; "there is too much at 3 kHz" tells you which slider to move, and it is what lets a review's description of a headphone connect to what you are hearing.

The ideas behind the controls

Octave
A doubling of frequency. Hearing works multiplicatively, so 100 to 200 Hz is the same perceptual distance as 1 to 2 kHz.
Presence region
Roughly 2 to 5 kHz, where the ear is most sensitive. Small changes here have outsized effects on perceived clarity and fatigue.
Sibilance
Harshness on s and t sounds, usually between 6 and 9 kHz. One of the easiest bands to learn to recognize.
Level matching
Comparing at identical loudness. Without it the louder version wins regardless of which is better.

EQ ear training FAQ

  1. Can I actually train this?

    Yes, and you can watch the curve go up on this page. The pattern-matching your brain runs on voices and instruments handles frequencies in the same way, once you start tagging things with names. The heatmap below the mode picker shows you which band needs the most work first.

  2. What if I can't hear some of the tones?

    Set the range above the modes to what you can hear. It starts at 100 Hz to 12.5 kHz, goes as wide as 20 Hz to 20 kHz, and every tone and answer option stays inside it. If a round is still silent, press "I can't hear it": the round is skipped without touching your score or streak, and when the tone was below 500 Hz or above 4 kHz the page offers to move that end of the range in. Silence on a tone between 500 Hz and 4 kHz usually means the volume is down or the sound is going to another device. Don't turn the volume up to reach a faint high tone, because the tones in the middle would then play too loud.

  3. How long until I have a "Golden Ear"?

    Two to six weeks gets you reliable third-octave identification on most material. Telling 3.5 kHz from 4 kHz on cue, which is roughly the resolution the Audiophile mode pushes toward, is closer to a six-month project for most people. Stay on one pair of headphones or monitors while you train so you are not also fighting changes in transducer or room. Plateauing twice on the way to the small intervals is normal and not a sign you have stopped improving.

  4. What are the five modes?

    Identify is the simplest: a sine tone, four answer options, pick the right one. Discriminate plays two tones back to back and you say which was higher. Octave throws a pair separated by a known musical interval (octave, fifth, tritone, or unison) and you name the gap. Audiophile is the painful one, where the gap shrinks to half a semitone and most ears tap out. Sweep plays a rising sine that stops somewhere on the spectrum, and you tell it where.

  5. Why does this matter for audio reviews?

    It is the difference between writing "a bit bright" and writing "6 kHz peak that pushes sibilance forward on female vocals." One sentence is information a reader can act on, A/B against their own setup, or argue with on the same terms. The other is a vibe report. Reviewers who skip frequency drills tend to keep writing the vibe-report version forever and never quite notice they are doing it.
