0 dB / octave
Equal energy at every frequency. Because we hear in octaves, it sounds bright and hissy — the classic "TV static".
Ten tests for your ears, headphones and speakers. Each one plays right here in your browser, draws what you hear and gives you an answer in a minute or two.
Headphones give the most exact answers. Start at a low volume and turn it up only as far as is comfortable.
Every sound is made on your device as you listen, so there is nothing to download and the tests keep working offline. A live picture shows what plays: the frequency, the two notes, the speaker that sounds.
The tests are for curiosity and practice, not a medical diagnosis. If your hearing changes suddenly, if one ear hears less than the other, or if a ringing does not go away, see a doctor or an audiologist.
For the hearing age, pitch and tinnitus tests, yes: headphones give the most exact results. The speaker, bass and phase tests are made for speakers.
Quiet. Start low and turn it up only until you hear the first tones clearly; never turn it up to catch a sound you cannot hear.
No. Your device and your headphones change the sound, so the results are a guide. An audiologist measures hearing with calibrated equipment.
Pick what you need. One tap to start, change anything and save it as your own.
Focus timer
The Pomodoro rhythm: focus with calm sound in your ears, then take a real break. A soft bell marks every change, so you never watch the clock. Every fourth break is a long one.
Sound while you work
Breathe
Follow the circle and the sound: it rises as you breathe in and falls as you breathe out. Choose a rhythm, or set your own, and pick what plays underneath.
Sound while you breathe
Any color of noise, from deep brown to bright violet — and everything in between.
Sound science
Same randomness, different tilt. Each color shifts energy between low and high pitches — here is what that sounds like.
0 dB / octave
Equal energy at every frequency. Because we hear in octaves, it sounds bright and hissy — the classic "TV static".
−3 dB / octave
Equal energy in every octave, so it sounds even to the ear. Steady rain, rustling leaves. A favorite for focus.
−6 dB / octave
Deep and warm, like a distant waterfall or a plane cabin. Masks voices and traffic without any hiss.
Equal-loudness curve
Shaped around how our hearing works, so every pitch seems equally loud. Balanced and soft.
+3 dB / octave
The mirror of pink: more treble than bass. Airy, crisp, like a light spray.
+6 dB / octave
Mostly treble, like hissing water. Sometimes used to mask high-pitched ringing.
Gentle tones to settle into: singing bowls, a slow warm drone, wind chimes tuned so every note fits.
Famous tones on pages of their own: hear them side by side, with honest facts.
How sound bends, shifts, rings and fools the ear, and why space is silent: hear it for yourself.
A purring cat, whales and dolphins, a nightingale in the dark, cowbells on a summer pasture. Wonderful in stereo.
Womb sounds are what a baby heard for nine months: a deep rush of blood flow, and the heartbeat.
Check your ears, headphones and speakers, each test on a page of its own with a live picture.
Ear Age · 60 seconds
Our ears lose the highest pitches first, and it starts early. Find the highest tone you can still hear and see the typical age for it.
Step 1 · Volume
Play the reference tone and set your volume so it's clear but comfortable. Leave it there.
Step 2 · Listen
Your result
A rough guide, not a diagnosis. Your phone, headphones and even this browser can cut the highest tones. Worried about your hearing? See an audiologist.
Check your headphones, find the deepest bass your setup can play, or play any pitch you like.
Headphones check
Each ear should get its own side. It matters for 8D, binaural beats and every stereo sound here.
Headphones on, then tap a side.
Bass test
Deep tones from 200 Hz down to 20 Hz, the bottom of human hearing. Mostly it tests your speakers or headphones.
Your setup plays down to
Tone generator
Start quiet: high tones and square waves get tiring fast.
Take it to bed
Add Ears & Waves to your home screen and it opens like any app — full screen, with its own icon. Everything it needs is saved on your device, so it keeps playing on a plane, in a tent or with Wi-Fi off.
Follow the circle. Eyes half closed, shoulders down. Press Stop whenever you like.
Stop after
The sound fades out slowly before it stops, so the silence doesn't wake you.
Wake me up
Saved mixes live on this device and appear first in Mixes.
Put the whole mix in a room, a cathedral or a canyon, and spread it around you. Best with headphones.

A few minutes of slow breathing, then your sleep sound carries on by itself and fades out. Lie down, follow the circle and let the screen go dark.
