What Are Binaural Beats?
Binaural beats are an auditory phenomenon that occurs when two tones of slightly different frequencies are presented to each ear through stereo headphones. Your brain perceives a third tone — the binaural beat — equal to the difference between the two frequencies. For example, if a 200Hz tone plays in one ear and 210Hz in the other, your brain perceives a 10Hz beat.
Brainwave Frequency Bands
Delta (0.5-4 Hz) — Associated with deep, dreamless sleep and physical restoration. Use Delta binaural beats when you want to fall into deep sleep.
Theta (4-8 Hz) — Linked to meditation, creativity, and the hypnagogic state between waking and sleeping. Theta beats may enhance mindfulness practice.
Alpha (8-14 Hz) — Connected to relaxed alertness, light meditation, and calm focus. Alpha beats can help reduce anxiety and promote a sense of well-being.
Beta (14-30 Hz) — Associated with active thinking, concentration, and problem-solving. Beta beats may support focused work sessions.
Solfeggio Frequencies
Solfeggio frequencies are a set of tones rooted in medieval Gregorian chant. Each frequency is believed to carry specific therapeutic properties:
- 396 Hz — Liberation from fear and guilt
- 417 Hz — Facilitating change and undoing situations
- 528 Hz — Known as the "miracle tone" for transformation and DNA repair
- 639 Hz — Enhancing connection and relationships
- 741 Hz — Awakening intuition and self-expression
- 852 Hz — Returning to spiritual order and intuition
Our generator creates pure sine wave tones at these exact frequencies using the Web Audio API, with individual volume control for each.
FAQ
Do I need headphones for binaural beats?
Yes, stereo headphones are required. Binaural beats work by sending slightly different frequencies to each ear, which creates the perceived beat in your brain. Speakers mix the channels together, eliminating the effect.
How long should I listen to binaural beats?
Most research suggests 15-30 minutes per session. Start with shorter sessions of 10 minutes and gradually increase. Listen at a comfortable volume — the effect does not depend on loudness.
Are binaural beats scientifically proven?
Research is ongoing. Some peer-reviewed studies show binaural beats may reduce anxiety and improve focus, though results vary. They are not a medical treatment and should complement, not replace, professional healthcare.
What are solfeggio frequencies used for?
Solfeggio frequencies are used in sound healing and meditation practices. Each frequency is associated with specific therapeutic intentions, from stress relief (396Hz) to enhanced intuition (852Hz). While scientific evidence is limited, many people report subjective benefits during meditation.
Can I play binaural beats and solfeggio frequencies together?
Yes. On this page you can activate binaural beats and any solfeggio frequency simultaneously. Some practitioners layer solfeggio tones over binaural beats for a combined meditation experience.
