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?

What is 7.83 Hz frequency used for?

The 7.83 Hz frequency (Schumann Earth Resonance) is used for travel days, relaxation practice, stress management. Earth's natural electromagnetic frequency for grounding, circadian support, and a deep connection to natural rhythms

Is 7.83 Hz safe to listen to?

7.83 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 7.83 Hz frequency?

People use 7.83 Hz for: sense of grounding and connection, circadian rhythm support, stress reduction, enhanced relaxation, natural rhythm alignment, improved sense of balance. These are the effects people associate with 7.83 Hz. No study has tested them for this frequency, so read them as ideas to explore, not as findings.

Can I listen to 7.83 Hz for free?

Yes, as a guest: every frequency, including 7.83 Hz Schumann Earth Resonance, plays free for 15 minutes per session. Membership removes the limit, from $9/month.

What is the 7.83 Hz frequency?

The Schumann resonance at 7.83 Hz is an electromagnetic phenomenon in the Earth-ionosphere cavity. Listening research on 7.83 Hz is limited. People use it as a low, grounding tone when they want to feel settled.

Proposed mechanism

Associated with Earth's natural electromagnetic rhythm, may support circadian alignment and promote a sense of grounding and calm

The science behind 7.83 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 7.83 Hz, no study has tested the specific effects described on this page. The papers below are background on sound and the brain, not evidence for this frequency.

How to use Schumann Earth Resonance

Suggested session

25-35 minutes daily, optimal timing 2 hours before natural bedtime. 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

The Physicist Who Heard the Earth Breathe

1952Munich, Germany

Dr. Winfried Otto Schumann

Professor of Physics · Technical University of Munich

Study summaryA 1952 physics paper predicting that the space between the Earth and the ionosphere resonates at low frequencies.

In 1952, physicist Winfried Otto Schumann worked out that the cavity between the Earth's surface and the ionosphere should resonate, like a giant bell, at very low frequencies.

His first estimate was around 10 Hz. Later measurements found the fundamental at about 7.83 Hz, now called the Schumann resonance, driven by lightning around the globe.

The number happens to sit near the boundary of the alpha and theta ranges seen in human EEG. That is a coincidence of ranges, not evidence of an effect on health.

People like 7.83 Hz as a low, grounding listen in the evening, and that is how we offer it.
