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.

What is 55 Hz frequency used for?

The 55 Hz frequency (Gentle Energy) is used for morning energy practice, self-care routines, pre-exercise preparation. Low-frequency tone for vitality, natural energy, and an invigorating restorative experience

Is 55 Hz safe to listen to?

55 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.

Can I listen to 55 Hz for free?

Yes, as a guest: every frequency, including 55 Hz Gentle Energy, plays free for 15 minutes per session. Membership removes the limit, from $9/month.

What is the 55 Hz frequency?

A low, gentle pulse people use for an upbeat morning listen. Specific research on 55 Hz is limited. The papers below are background on sound and alertness, not trials of this frequency.

Proposed mechanism

May support a sense of vitality and energy through auditory stimulation pathways associated with physiological arousal

What people listen for

These are the effects people associate with 55 Hz. No study has tested them for this frequency, so read them as ideas to explore, not as findings.

The science behind 55 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 55 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 Gentle Energy

Suggested session

25-35 minutes morning use for a natural energy boost. 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

When Science Listens to Sound

2017San Diego, California

Dr. Tamara Goldsby

Researcher, Department of Family Medicine · University of California San Diego

Study summaryAn observational study of a single singing-bowl meditation session, without a control group.

In 2017, Tamara Goldsby and colleagues at UC San Diego asked 62 adults to rate how they felt before and after a one-hour sound meditation with singing bowls, gongs and bells.

After the session, participants reported feeling less tense and more at ease on standard mood questionnaires.

The study had no control group, so it cannot say how much of the change came from the sound itself rather than resting quietly for an hour.

We share it as an honest picture of where sound-meditation research is: promising, early, and worth trying for yourself.
