What does Freqium play?

Freqium plays specific sound tones (measured in Hz) intended for sleep, calm, and focus. Different ranges are associated with different states — delta (1-4 Hz) for deep sleep, theta (4-8 Hz) for meditation, alpha (8-14 Hz) for relaxation, and gamma (30-100 Hz) for focus.

Is frequency listening clinically proven?

Brainwave entrainment — the brain synchronizing to external audio stimuli — is documented in auditory neuroscience since the 1970s via EEG studies. The Frequency Following Response (FFR) is consistently replicated. That is not a clinical-proof claim. Each Freqium frequency is labeled Emerging, Traditional, or Speculative.

What frequency is for calm?

432 Hz is the most commonly studied tone we offer for calm. People use it to slow down and feel calmer. Freqium offers a free 432 Hz Find Calm session.

What is the best frequency for sleep?

Delta frequencies (0.5-4 Hz), particularly 1.5 Hz, are associated with deep sleep. The Schumann resonance (7.83 Hz) is often used for grounding. Freqium's Deep Sleep Protocol combines both.

Do I need headphones for Freqium sessions?

Yes, headphones at a low, comfortable volume are recommended. They are required for binaural pairs (one tone per ear), which the iOS app uses for frequencies under 20 Hz and the landing page demos use.

Freqium offers a 15-minute guest session on any of the 27 frequencies, no account needed. Membership removes the limit. Two launch offers until Nov 30, 2026: Monthly at $9/month instead of $29, kept for as long as you stay subscribed (or $69/year instead of $290), and Founding Lifetime at $79 once for the first 100 members. After that, membership is $29/month or $290/year.

What are wellness frequencies?

Wellness frequencies are specific sound tones (measured in Hz) that research suggests can influence brainwave patterns through a process called brainwave entrainment. Different frequencies target different states — delta waves (1-4 Hz) promote deep sleep, theta waves (4-8 Hz) aid meditation, alpha waves (8-14 Hz) enhance relaxation, and gamma waves (30-100 Hz) support focus and cognition.

What is the difference between binaural beats and solfeggio frequencies?

Binaural beats play two slightly different tones in each ear, creating a perceived frequency difference that encourages brainwave entrainment. Solfeggio frequencies are specific single tones (174 Hz, 396 Hz, 432 Hz, 528 Hz, etc.) from an ancient musical scale. On the web, Freqium plays single tones (with an audible harmonic for very low frequencies); the iOS app plays frequencies under 20 Hz as binaural pairs.

Which frequency is best for calm?

432 Hz is the tone people reach for most when they want to feel calmer. Freqium offers a free 432 Hz Find Calm session with guided breathing.

Are frequency sessions free?

Guests can play any of the 27 frequencies for 15 minutes. 15 min free · Headphones recommended. Membership removes the limit. Two launch offers until Nov 30, 2026: Monthly at $9/month instead of $29, kept for as long as you stay subscribed (or $69/year instead of $290), and Founding Lifetime at $79 once for the first 100 members. After that, membership is $29/month or $290/year.

Is 432 Hz safe to listen to?

432 Hz is generally safe for most adults when used with headphones at moderate volume. Precautions: If you are pregnant, use an implanted device, or a clinician is already caring for you, talk with them before listening. Stop if you feel dizzy or distressed. This is a wellness tool, not a medical device. Consult a healthcare provider if you have medical conditions.

What are the benefits of 432 Hz frequency?

People use 432 Hz for: a sense of letting go of tension, enhanced calm and emotional balance, slower, easier breathing, improved sense of wellbeing, unwinding, gentle mood elevation. Early studies on 432 Hz describe the effects below. They are small and still being repeated, results vary from person to person, and none of this is a medical claim.

Can I listen to 432 Hz for free?

Yes. 432 Hz Find Calm is available on Freqium with 15-minute guest sessions. 15 min free · Headphones recommended.

What is the 432 Hz frequency?

A small pilot (Calamassi & Pomponi, 2019) compared music tuned to 432 Hz with music tuned to 440 Hz. It was small, and it has not been repeated in a larger trial. People use 432 Hz as a calm listening tone.

Proposed mechanism

A soft, slightly lower tuning that many listeners find calm and easy to settle into

What early studies describe

Early studies on 432 Hz describe the effects below. They are small and still being repeated, results vary from person to person, and none of this is a medical claim.

The science behind 432 Hz

Brainwave entrainment is the idea that the brain’s electrical activity can fall into step with a steady rhythm you hear. A related response, the Frequency Following Response (FFR), can be measured with EEG.

For 432 Hz there are frequency-specific studies, listed below. They are early and mostly small, so read them as a reason to try it, not as proof that it will work for you.

How to use Find Calm

Suggested session

20-30 minutes when you want to slow down, or as a calm practice twice daily. Individual experiences may vary

🎧

Use headphones

Over-ear or in-ear, at a low volume. They keep the tone clear without turning it up.

🧘

Find a quiet space

A calm room makes it easier to settle in and notice how you feel.

📅

Be consistent

A short session every day is easier to keep. Notice how you feel and adjust.

The research behind this sound

A Small Italian Study on 432 Hz Tuning

2019Florence, Italy

Dr. Diletta Calamassi

Researcher in Nursing Science · University of Florence

Study summaryA small double-blind pilot study comparing the same music tuned to 432 Hz and 440 Hz.

At the University of Florence, Diletta Calamassi and Gian Paolo Pomponi asked a simple question: does the tuning of music, with the melody and rhythm unchanged, make any difference to listeners?

In a small double-blind pilot, 33 volunteers listened to the same pieces tuned to the standard 440 Hz and to 432 Hz, without knowing which was which.

The authors reported a slightly lower average heart rate with the 432 Hz version, and listeners said they felt a little more focused and satisfied. Other differences were small.

It is one small study, and the authors call for larger ones. We share it because it is the clearest research on 432 Hz tuning, not because it proves an effect.
