Rife frequency list (commonly referenced values)
The Consolidated Annotated Frequency List (CAFL) is the most widely referenced community database of Rife-style frequencies. Below is a subset of the values people look up most often. To hear one, type its number into the generator above and press Play — or set it on the slider and dial in the exact value.
Every entry below is described only as "commonly referenced" for a purpose. These are popular descriptions, not proven effects, and nothing here should be read as medical advice.
| Frequency | Commonly referenced for |
|---|---|
| 20 Hz | commonly referenced for low-end grounding and deep relaxation |
| 72 Hz | commonly referenced for relaxation and a settling feel |
| 120 Hz | commonly referenced for calm and a balanced mood |
| 160 Hz | commonly referenced for comfort and a steady backdrop |
| 174 Hz | commonly referenced for rest and comfort (also a Solfeggio tone) |
| 285 Hz | commonly referenced for rest and a quiet, settled state |
| 304 Hz | commonly referenced for energy and balance in popular lists |
| 432 Hz | commonly referenced as the "natural tuning" in meditation circles |
| 440 Hz | the standard A4 reference pitch for tuning instruments |
| 528 Hz | popularly referenced in meditation and sound-healing culture |
| 727 Hz | one of the most commonly referenced Rife frequencies |
| 728 Hz | popularly referenced alongside 727 and 787 in Rife lists |
| 787 Hz | popularly referenced alongside 727 and 728 in Rife lists |
| 880 Hz | a bright A5 reference, commonly referenced in Rife lists |
| 1,000 Hz | commonly referenced for focus and clarity |
| 1,550 Hz | commonly referenced for balance |
| 2,000 Hz | commonly referenced for focus and mental clarity |
| 2,489 Hz | commonly referenced in popular Rife frequency lists |
| 2,720 Hz | commonly referenced in popular Rife frequency lists |
| 5,000 Hz | commonly referenced for sharp, upper-range listening |
| 10,000 Hz | commonly referenced for high-frequency listening tests |
Tip: enter a value from this table into the generator above to play it. The table is a reference list, not a prescription — pick whatever sounds useful or pleasant to you.
Rife vs. Solfeggio vs. binaural beats
People often bundle these three together, but they are quite different once you look at how they work.
Rife frequencies
A single, audible tone at a chosen frequency, played through a speaker or headphones. The values come from a historical list popularized in the early 20th century.
Solfeggio frequencies
A set of six tones (396, 417, 528, 639, 741, 852) popular in meditation and sound-healing culture. Like Rife values, they are single audible tones — the difference is mostly the cultural story behind the numbers, not the physics.
Binaural beats
Two slightly different tones, one per ear, such that the brain perceives a third "beat" at the difference between them. This requires headphones to work — one tone is not routed to the other ear through open speakers.
In short: Rife and Solfeggio tones are ordinary audio frequencies you can hear from a speaker, while binaural beats are a stereo effect that needs headphones. This page generates the simple single-tone kind. Read more in our guide to the Solfeggio frequencies, browse the 528 Hz generator and the 432 Hz generator, or try a hearing test.
Who was Royal Rife?
Royal Raymond Rife was an American inventor active in the 1920s and 1930s, known for building elaborate microscopes and a device he called a "beam ray." His work attracted attention and controversy during his lifetime. The frequency lists that carry his name today descend from material produced in this era.
Modern medical and fact-checking organizations, including cancer charities and research bodies, have concluded there is no reliable scientific evidence that Rife machines or Rife frequencies treat any illness, and that the devices are not approved for medical use. This is an educational page — it presents the historical background and the frequency values as cultural references, not as a therapy, and it makes no claim about what the frequencies can do to your health.
How to listen to a Rife frequency
- Pick a frequency from the table above and type it into the generator (or drag the slider to the value).
- Keep the volume low and comfortable — you should barely hear it in the background.
- Press Play and listen for a short, relaxed session. Around 5 to 10 minutes is a reasonable start.
- If you want to keep exploring, switch the waveform (sine, square, triangle, sawtooth). The same frequency sounds very different depending on the waveform.
- Stop whenever you like. The tone auto-stops after 60 seconds.
There is no fixed "dose" because these are ordinary sound frequencies, not a treatment. Use them as a sound you enjoy, at a level that stays comfortable. If you have a health concern such as pain, tinnitus, or an ongoing condition, talk to a qualified professional instead of assuming a frequency can help.
Frequently asked questions
Do Rife frequencies work?
The term "Rife frequencies" comes from a set of values popularized in the 1920s and 1930s by Royal Rife, an American inventor. There is no reliable scientific evidence that a specific frequency treats or cures any illness — major medical organizations describe these claims as unsupported. Many people still enjoy the tones for listening, relaxation, or curiosity, which is a fine reason to use them. Just do not expect a medical effect.
Are Rife frequencies safe to hear?
As an audible tone at a comfortable, low volume, they are no different from any other sound and are generally safe to listen to. The key is volume: keep it low and stop if anything feels too loud or uncomfortable. This tool produces ordinary audio tones; it is not a medical device and makes no health claims.
Do you need headphones for Rife frequencies?
No. Rife frequencies are played as a single, audible tone from the speaker, so headphones are not required. (This is different from binaural beats, which send a slightly different frequency to each ear and do need headphones to create a perceived third tone.) If you do use headphones, keep the volume moderate.
How long should I listen to a Rife frequency?
There is no medically established dose, because these values are not medical treatments. The practical answer is: start short and keep it comfortable — 5 to 10 minutes at a low volume is a reasonable first listen. The tone auto-stops after 60 seconds to avoid running in the background by accident. Stop whenever you want.
