Each ear hears a slightly different pitch, so you hear a beat at the difference (a binaural beat). Use earphones.
Choose a band
The slowest brainwave band (about 0.5-4 Hz), common in deep (slow-wave) sleep.
In a small study of 24 people (2018), those who heard a 3 Hz beat (left 250 Hz, right 253 Hz) after falling asleep reached the deepest sleep stage (N3) sooner and stayed in it longer. This tone uses the same pitches.
Left 250 Hz · Right 253 Hz
A band (about 4-8 Hz) that rises when drowsy, in light sleep, or in deep meditation.
We found no direct evidence that theta beats help you fall asleep. In one study (1998), people did worse on an attention task with theta/delta beats than with beta, so it is not a good fit for work or study.
Left 250 Hz · Right 256 Hz
A band (about 8-13 Hz) common when awake and relaxed with eyes closed.
A meta-analysis of 22 studies (2019) found a medium overall effect of binaural beats on lowering anxiety and helping memory and attention. The studies used different frequencies, so this is not an effect of 10 Hz alone.
Left 250 Hz · Right 260 Hz
A band (about 13-30 Hz) common when awake and concentrating.
In a study of 29 people (1998), 16 and 24 Hz beats during a 30-minute watch task led to more correct detections, fewer false alarms and less negative mood than 1.5 and 4 Hz beats. Brainwaves were not measured.
Left 432 Hz · Right 448 Hz
A fast band (about 30 Hz and up) linked to rapid information processing.
One study (2020) found that a 40 Hz beat (left 420 Hz, right 460 Hz) made the brain's 40 Hz rhythm stronger (measured with MEG) and that next-day attention training gains were better than with 16 Hz. The overall effect was small, and another study saw better attention but no brainwave change.
Left 420 Hz · Right 460 Hz
Mix and listen
Plays the brainwave tone together with nature sounds, instruments and a melody (background music). When the time is up, they all fade out together.
A meta-analysis of 22 studies (2019) found that mixing noise into the beat was not needed for the effect. Pick the mix that sounds comfortable to you.
Listen for
It fades out over the last 2 minutes. Keep the volume low for sleep.
A systematic review of 14 studies (2023) found 5 results in line with the idea that brainwaves follow the beat, 8 against it, and 1 mixed. The effect is not settled and this is not a treatment. Do not listen while driving or operating machinery. See a professional if you have health concerns.
Breathe in as the circle grows, out as it shrinks.
Rest a hand on your belly and feel it rise as you breathe in and fall as you breathe out. If you feel dizzy, stop and breathe normally.

The pitch of each sound and what research has found so far. Where evidence is weak, we say so.
| Sound | Pitch | What research found |
|---|---|---|
| Singing bowl | 131-523 Hz | An observational study of 62 people reported less tension, anger, fatigue and depressed mood after meditation. With no control group, the sound cannot be named as the cause. |
| Crystal bowl | 131-523 Hz | We found no study of crystal bowls on their own. They can be used to focus on a clear tone. |
| Tingsha bells | 1,240-2,650 Hz | We found no study of its effects. Its short, high tone can mark the start and end of meditation. |
| Shaman drum | 90-180 Hz | A 10-week study of people drumming together found less anxiety. We found no result for listening alone. |
| Tuning fork | 128-512 Hz | We found no solid clinical study of its effects. It can be used to focus on a single tone. |
| Gong | 65-262 Hz | We found no study of gongs on their own. The long tone can help pace your breathing. |
| Handpan and tongue drum | 147-587 Hz | We found no study of handpans or tongue drums. You can rest while listening to the gentle melody. |
| Chimes | 880-3,520 Hz | We found no study of chimes. They can fill a space with clear tones or mark the start of meditation. |
| Wood chimes | Mixed frequencies | We found no study of wood chimes. They work as a natural background sound. |
| Ocean drum | Mixed frequencies | We found no study of ocean drums. You can breathe along with the rising and falling sound. |
| Nutshell and seed shakers | Mixed frequencies | We found no study of shakers. You can focus on the steady rhythm. |
| Rainstick | Mixed frequencies | We found no study of rainsticks. It works as a quiet, rain-like sound. |
| Rain | Mixed frequencies | A review of natural sounds found less stress and better mood, with water sounds showing the largest health-related effects. |
| Stream | Mixed frequencies | In a review of natural sounds, water sounds showed the largest health-related effects. |
| Wind | Mixed frequencies | Natural sounds as a group were linked with less stress, but we found no result for wind alone. Bird sounds had the largest effect on stress. |
| Ocean waves | Mixed frequencies | In a review of natural sounds, water sounds showed the largest health-related effects. |
| Birds and insects | Mixed frequencies | In a review of natural sounds, bird sounds had the largest effect on stress. |
| White noise | All frequencies | Evidence that it improves sleep was rated very low quality. See the note below. |
One study found more rest-and-digest (parasympathetic) activity while people listened to natural sounds, though people who were already relaxed showed slightly more stress. Effects differ from person to person, so choose a sound you find comfortable.
White noise mixes all pitches evenly. Pink noise gets quieter toward higher pitches, and brown noise falls off faster still. People often use them to mask surrounding noise, but evidence for better sleep is not strong. In a 2026 sleep study, pink noise played all night reduced REM sleep. For sleep, a low volume and short use are the safer choice. We found no peer-reviewed trial of brown noise itself.
We could not confirm through peer-reviewed research that specific pitches such as 528 Hz or 432 Hz heal the body. Use the pitch bar to find a comfortable sound, not as a treatment.
This guide is general information and does not replace diagnosis or treatment. See a professional if you have symptoms. Keep the volume comfortable.

Free healing sounds online. Listen to real recordings of rain, ocean waves and streams with singing bowls and white noise in a 360 forest, then rest with a breathing guide and a meditation timer. No account is needed.
The standard singing bowl is made by this site. You can choose a real recording under sound type. Rain, stream, wind, wave and bird sounds are also real recordings.
Choose diaphragmatic breathing in the breathing guide: breathe in through the belly for 4 seconds as the circle grows, hold for 2, then breathe out slowly for 6 as it shrinks. 4-7-8 and box breathing (4-4-4-4) are also available.
A stopwatch that counts up, a countdown from a chosen time, and a custom time you type in minutes and seconds. A singing bowl can ring at the start and the end.
Yes. Rain or white noise at a low volume works well. Closing the browser or tab stops every sound.
