What if your toothbrush vibrated at 528 Hz?

An electric toothbrush shakes you harder than a 50,000-watt speaker a meter away ever could — every single day, at some random frequency. No more. This one runs at the frequencies you choose. Zero extra effort: you already brush your teeth.

Speakers huff and puff. Your toothbrush grabs you and shakes.

To really move something, you have to grab it and shake it directly. That's what your toothbrush does to you every single day — with a force that would take something like 50,000+ watt speakers one meter away to match.

So why leave the frequency to chance? Let's grab the leash and take control. Now you can enjoy a few minutes of hyper-powerful 528 Hz vibration every morning, without adding a single second to your routine.

HOW CAN THERE BE TWO FREQUENCIES?

Think engine RPM — and your foot on the gas.

Run the motor at 528 Hz: that's the RPM. Now imagine playing back-and-forth with the gas pedal at a very low frequency. The engine still runs at 1000+ RPM, yet you've superimposed a slow pulse on top. That's exactly what we do.

The two mix and shift: a 528 Hz peak splits into three, spaced 7.83 Hz apart. It sounds much, much better this way — try any combination in the simulator above. The tones on the brush are generated digitally, with very high precision.

Measured spectrum: peaks at 520, 528.1 and 535.8 Hz, spaced 7.83 Hz apart

The real thing, measured: the 528 Hz peak split into three, 7.83 Hz apart. Recorded with a regular phone microphone, so there's slight inaccuracy — the brush itself generates the tones digitally.

WHY BOTHER?

Electric toothbrushes sometimes use a two-frequency mode like this anyway, because it cleans better. We just choose frequencies worth choosing.

The motor frequencies

528 Hz
The “frequency of love”

By far the most popular healing frequency. One study found 528 Hz-tuned music significantly increased oxytocin and compared it with 440 Hz music on cortisol [13]; a rat study measured higher brain testosterone after exposure [14].

432 Hz
The tuning they moved away from

Double-blinded studies report 432 Hz music lowering heart rate, respiration [9,10] and stress [11] versus standard 440 Hz, and better sleep quality in an EEG nap study [12].

417 Hz
Solfeggio

According to enthusiasts, it removes negative energy and helps your sacral chakra. Don't ask me, I'm just a humble toothbrush engineer.

396 Hz
Solfeggio

Supposed to release you from guilt and/or fear. Sounds like a good deal!

285 Hz
Solfeggio

Said to assist cellular regeneration. Very popular — and the electromagnetic purr you heard above.

174 Hz
The lowest Solfeggio

They say it's good against physical pain. Too low to vibrate a small head strongly — it's here for future, larger resonant attachments.

The pulse frequencies — in your brain's own range

Your brain runs faster when you're hyped up and slower when you're relaxed — and light and sound are known to influence it. The pulse frequencies sit right inside those ranges.

Brainwave ranges: gamma 30–100 Hz, beta 13–30 Hz, alpha 8–12 Hz, theta 4–7 Hz, delta 0.5–3 Hz, each with its typical state
0.50 Hz

The very lowest brain frequency — used for meditative flow states, relaxation and deeper sleep. The final boss of the lower range.

7.83 Hz

The Schumann resonance: Earth's electromagnetic field pulses at 7.83 Hz. If there's any frequency we're naturally accustomed to, it's this one.

14.3 – 33.8 Hz

The second through fifth Schumann frequencies: 14.3, 20.8, 27.3 and 33.8 Hz. Cycle up in the morning, down in the evening?

40 Hz

The most studied sound frequency of all, a reliable way to induce gamma waves, researched for cognitive decline. The inventor finds it harsh — but the research earned it a slot.

ALL GOOD THINGS COME IN THREES

Three brush heads. Two of them are real hair.

Three bamboo brush heads: black nylon, white horse hair and tan boar bristle

Nylon

A fairly traditional plastic-bristle head. Nothing fancy or special about it. It does the job!

Horse bristle

Natural hair, and the softer of the two. A gentle match for the calmer frequencies.

Macro close-up of natural tan boar bristles on a bamboo brush head, with water droplets
Boar bristle

Natural hair with a slightly harder, rougher surface — depending on your favorite frequency, you might prefer it.

Replacement heads are easy to swap — and last time I checked, ours are cheaper than Amazon. (Why am I telling you this?)

IPX7 WATERPROOF

Bring it into the shower. It can take it.

IPX7 certified: it survives 1 meter underwater for 30 minutes, so a daily shower is no problem at all. Just skip the very hot water, and let it dry off afterwards — especially the bamboo.

ISN'T THIS JUST PLACEBO?

One would certainly think so. Let's look into it.

Brain scans showing activation in the right superior temporal gyrus, anterior cingulate cortex and right amygdala after 12 Hz infrasound
12 HZ · BELOW HUMAN HEARING

If we can't hear it, it shouldn't affect us much… right?

Here's a brain after some 12 Hz. A very reliable pattern: some activated zones handle hearing, others emotional control and the autonomic nervous system.

Did you notice I recolored someone's brain scans to match the brand colors? That's what you call dedication.

Cells don't have ears

Human cells in a dish — not equipped for auditory processing at all — significantly changed behavior and hormone activity in response to sound [1].

Sound you can't even hear

Below 20 Hz is infrasound. Animal studies report grim effects: reduced learning and protein expression in rats at 16 Hz [3], lowered testosterone and libido [4], even vascular fibrosis [5].

A concert crowd at 17 Hz

At a British double concert, organizers secretly added 17 Hz to the music — and audiences reported significant discomfort [7]. Some even link infrasound to “ghost sightings” [6].

Can snails feel placebo?

Researchers played tuning forks to snails in a maze. At 320 Hz, completion time dropped from 16 minutes to 5, and the snails were described as extremely active and alert [16].

WHAT'S THE CATCH?

There is one. I think you can accept it.

Normal “sonic” toothbrushes are built first, then tested across a frequency range to find whichever gives the strongest vibration. That's the only thing they engineer for.

We do it backwards: we already know our frequencies, so we choose the design and materials to resonate decently at them. With several frequencies, some will vibrate harder than others. Want to clean a few seconds faster? Use the loudest one.

Manual toothbrushes work pretty well with no vibration at all — so slightly lower amplitude isn't the end of the world. This is version one. Future models will surpass the big brands in every way.

Questions, answered

If I pre-buy, how long will I wait?+

If nothing unforeseen happens — knock on 528 Hz-resonant wood — every pre-order ships in December 2026.

When will we know if it's happening?+

By mid-October 2026 at the latest. I've got a feeling this will be a big success, so let's plan the victory parade instead. Who's invited?

Can you really deliver anywhere?+

Almost. North Korea, Greenland, no problem. But rechargeable batteries are complicated in some places: we can't ship to China, Italy, Hong Kong, Japan, Laos or Madagascar. Active war zones can also be impossible.

Can I shower with it?+

Yes! It's IPX7 certified — 1 meter underwater for 30 minutes. A shower is no problem. Avoid overheating it in hot water, and let everything dry off quickly afterwards, especially the wood.

Wait — is there a secret frequency?+

Of course there is. Don't act so surprised! Toggle past the final mode and, instead of shutting off, every LED blinks and it outputs 174 Hz — useless for brushing today, very useful once larger attachments arrive.

What if we attached something other than a brush head?+

We'll definitely get creative. It's a 1-watt mechanical oscillator, and the larger the resonant body, the lower the frequency. 285 Hz would suit something bigger — like a goat-hair face brush. (Don't worry, it won't shake your building like Tesla's oscillator.)

Any esoteric electrical features?+

Not yet. Accessories that use the brush to charge water are on the drawing board. If you have no idea what that means, explore the rest of the site — you're in for a surprise.

What about EMF?+

I tried mu-metal wrapping and copper-coil shielding; neither helped. So it has similar EMF to other toothbrushes of its power. On the bright side, the motor makes a 7.83 Hz magnetic field in your hand — the same as the Earth beneath you. Have ideas? I'd love to try them.

Are you familiar with the “brown note”?+

Uh, no..

What's your return policy?+

It's a hygiene product — a used toothbrush is preposterous — so returns are only accepted for defects. Hopefully that never happens!

How can I contact you?+

If you asked the previous question, please don't! Otherwise, send toothbrush questions to hello@thehealthiestwebsite.com.
