What are binaural beats? A guide for producers and sound healers
Binaural beats are a beat you hear when each ear gets a slightly different steady tone. If the left ear hears 200 Hz and the right ear 207 Hz, you perceive a soft pulse at the difference, 7 Hz, even though neither tone pulses. The beat is created by the brain, not in the air, so binaural beats only work with headphones.
Who discovered binaural beats?
The Prussian physicist Heinrich Wilhelm Dove described them in 1839. In the 1970s Gerald Oster's article Auditory Beats in the Brain (Scientific American, 1973) brought them to a wider audience, and Robert Monroe's Hemi-Sync recordings made them a staple of meditation and consciousness practice.
How do binaural beats work?
Two parts make a binaural beat:
- The carrier, the pitch you actually hear, usually 100 to 500 Hz. Lower carriers are easier to listen to for a long time.
- The beat, the difference between the ears, usually 0.5 to 40 Hz.
The left ear gets the carrier minus half the beat, the right ear the carrier plus half the beat. Above about 30 to 40 Hz of difference the effect fades and you simply hear two tones.
What are the brainwave bands?
Binaural beat practice names beats after the EEG frequency bands they sit in. The traditional associations used in meditation and sound healing are:
| Band | Beat | Traditional association |
|---|---|---|
| Delta | 0.5–4 Hz | deep sleep |
| Theta | 4–8 Hz | dreamlike states, insight, deep meditation |
| Alpha | 8–13 Hz | relaxed, calm awareness |
| Beta | 13–30 Hz | alert, focused work |
| Gamma | above 30 Hz | high focus, "flow" |
These are traditions and listening intentions, not medical effects. Research on how much a binaural beat shifts brain activity is mixed, so treat them as a creative and relaxation tool.
What is the Schumann resonance beat?
7.83 Hz is the fundamental of the Schumann resonances, the electromagnetic resonances of the cavity between the Earth's surface and the ionosphere. It is a popular beat in sound healing, and its octaves (1.96, 3.92, 15.66 and 31.32 Hz) land in Delta, Theta, Beta and Gamma.
Binaural beats or isochronic tones?
Isochronic tones pulse one tone on and off at the beat rate. They work on speakers and in a room full of people, and the pulse is obvious. Binaural beats are smoother and subtler but need headphones. Many sessions combine both.
How do I use binaural beats in music?
- Put the generator on its own track under the music, quietly, and tune the carrier to a note in your key, dropped an octave or two.
- Restart the beat with your arrangement so it stays in time.
- Remember that most listeners won't wear headphones, so add an isochronic pulse if the beat matters on speakers.
- Avoid heavy stereo widening or mid/side processing on the beat track; it smears the difference between the ears.
How do I use binaural beats in a healing session?
Move gradually. A common shape is to start in Beta or Alpha, descend a band at a time to Theta, rest there, then return. Use a low carrier, a gentle noise bed and a fade at the end. Keep the volume low, and read a health notice before using entrainment with clients: people with epilepsy, heart conditions or who are pregnant should check with a doctor first, and nobody should listen while driving.
