the sound.
A few starting points for curious ears. Explore what the tones mean, how to listen and what the research can—and can’t—tell us.
try sonalunewhat is binaural listening?
With stereo headphones, Sonalune can send a slightly different tone to each ear. Together, they can create the perception of a gentle beat at the difference between the two frequencies.
left ear220 Hzright ear226 Hzperceived beat6 Hz
The 6 Hz is the difference between the tones, not an extra low note coming from your headphones. Use stereo headphones with mono audio switched off to keep the two tones separate.
That perceived beat does not mean your brainwaves will automatically follow it. A 2023 systematic review found inconsistent evidence for brainwave synchronisation.
what are solfeggio tones?
“Solfeggio frequencies” is a name used in contemporary meditation and sound practices for a collection of pitches, including 396, 417, 528, 639, 741 and 852 Hz. Sonalune also offers 174, 285 and 963 Hz, often included in expanded collections.
Hz means cycles per second: it describes a tone’s frequency. These numbers are pitches to explore, rather than binaural beat rates. You can listen to a single tone through speakers or headphones.
People attach different spiritual meanings to these frequencies, but those associations are not established medical effects. There is not strong evidence that each exact pitch produces a unique healing benefit. Choose a tone because you enjoy how it sounds.
what might I get from listening?
You might enjoy a quiet backdrop for meditation, a sound to return your attention to, or a small ritual for winding down. Some people find steady tones soothing; others prefer softer textures or silence.
These are possibilities to explore, not guaranteed effects of a particular frequency. Research on binaural beats is still developing, and studies of other recordings do not establish benefits for Sonalune itself. Sonalune has not been clinically tested and is a listening tool, not a treatment.
Notice how the sound feels to you. There is no special state you need to reach, and no need to keep listening to a tone you find uncomfortable.
your first five minutes
- Get comfortable. Choose a quiet moment and put on stereo headphones if you want to explore binaural beats.
- Start simply. Open Sonalune, choose a preset and set the session length to five minutes.
- Keep it gentle. Start with the volume low, then adjust only to a comfortable level.
- Let the sound be there. Breathe naturally. If your attention wanders, you can return to listening without forcing it.
- Find your preference. Afterwards, try a different texture or save a preset you enjoyed. Lower the volume or stop if listening feels uncomfortable.

a slower approach
to sound.
Slowfield Audio is an independent audio project by Andrew John, bringing a love of ambient music into tools for listening and making.
We’re interested in texture, movement and the unexpected places a sound can take you. Sonalune is an invitation to explore at your own pace.
