0 dB / octave
Equal energy at every frequency. Because we hear in octaves, it sounds bright and hissy — the classic "TV static".
The best known of the Solfeggio frequencies: hear it as a pure tone, next to the standard note C, and as a melody tuned around it. Facts and comparisons follow.
Tap an example to play it, and again to pause. 528 Hz is about 16 cents above the standard C (523.3 Hz): close, but you can hear it when one follows the other.
528 Hz is the best known of the Solfeggio frequencies, often called the “love frequency” or the “miracle tone”. In music it is a slightly sharp C: the standard C an octave above middle C is 523.3 Hz.
It sounds bright and clear, and many people use it for meditation. That is reason enough to enjoy it; the healing claims around it are not backed by evidence.
| 528 Hz | C at standard pitch | A at standard pitch | |

| What it is | One of the nine Solfeggio frequencies, called the “love frequency” | The note C an octave above middle C (C5) | The note A above middle C, the tuning standard |

| Against 440 Hz | Exactly 6:5, a pure minor third above | An equal-tempered minor third above | — |

A pure tone at 528 vibrations per second, one of the nine Solfeggio frequencies. Musically it sits just above the note C.
No. That claim comes from popular books, not from research, and sound at listening levels cannot change DNA.
A small 2018 study of nine adults found lower stress hormones after 528 Hz music. It is one tiny experiment, so treat it as a curiosity, not proof.

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.

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.

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.

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.
