174 Hz Frequency Benefits: Pain, Sleep and Chakra Claims vs Research

174 Hz frequency benefits are claims without trials behind them. No study tests a 174 Hz tone for pain, inflammation or tissue healing in people. One small 2026 sleep study used 174 Hz as the base tone of a binaural beat, and the variable under test was the beat.

174 Hz is the lowest number on the modern nine-tone Solfeggio chart. Sellers call it the pain relief and grounding frequency. Music in general eases pain in a review of 97 trials and improves self-rated sleep in a review of 13. Those trials used music and never isolated a single pitch.

Below, 10 common claims are graded against the evidence and the 3 studies that use 174 Hz are summarized. Volume is the one risk with evidence behind it.

174 Hz benefits: 10 claims vs evidence

What is 174 Hz?

174 Hz means 174 vibrations per second. It is a low pitch, close to the F below middle C. In standard tuning (A = 440 Hz) that note, F3, sits at 174.61 Hz. 174 Hz is about 6 cents flat of it, and a cent is one hundredth of a semitone. In 432 Hz tuning, F3 drops to 171.44 Hz and 174 Hz lands about 26 cents sharp of it.

The number comes from the modern Solfeggio wellness chart. The solfege syllables (ut, re, mi) go back to Guido of Arezzo in the 11th century and had no fixed frequencies. History write-ups credit Joseph Puleo with six of the chart numbers in the 1970s, worked out through numerology. They credit Leonard Horowitz with adding 174, 285 and 963 Hz in 1999. No medieval source lists 174 Hz, so claims of use "for centuries" have no source behind them.

A "174 Hz track" can be a pure tone, a drone, music built around 174 Hz, or a binaural beat on a 174 Hz carrier. These are different exposures. A result from one does not transfer to another.

A binaural beat plays a slightly different tone in each ear. The brain hears the gap as a slow pulse. A 174 Hz tone in one ear and 176 Hz in the other gives a 2 Hz beat.

Studies that use 174 Hz

A PubMed search for "174 Hz" returned 9 papers on 7 October 2026. Six use the number for unrelated things, such as heart signals, slurry pipelines and chemistry. Three involve 174 Hz sound.

Sleep: a 2026 binaural beat study

Researchers in Tehran played a delta binaural beat on a 174 Hz carrier tone to 20 healthy students. Delta is the 0.5 to 4 Hz range of brain waves in deep sleep. Each student slept three nights in the study, one with the beat and two without any intervention. The beat did not shorten the time taken to fall asleep. It increased deep (N3) and REM sleep and reduced the number of awakenings and the time spent awake, measured by EEG.

The group was small and healthy, there was one test night, and no sham sound was used. The authors credit the delta beat, not the 174 Hz carrier, and call for further studies. The result does not show that a plain 174 Hz tone helps sleep or treats insomnia.

Safety: zebrafish embryos

A 2026 noise-pollution study exposed zebrafish embryos to 40, 174 or 528 Hz sound for 90 minutes a day over 10 days. 40 Hz raised mortality and caused malformations and oxidative stress. 174 Hz showed no adverse effects on any measure. 528 Hz caused no visible damage but raised one stress enzyme.

The study used fish embryos and measured harm only. It is still the only direct safety data on 174 Hz sound.

Tuning forks: a 2020 Biofield Tuning study

Biofield Tuning practitioners sweep an unweighted 174 Hz tuning fork through the space around the body and report "perturbations". In a 2020 study, three practitioners checked the same 10 volunteers. Their locations matched within 2 inches only 33% of the time, and the statistics showed poor agreement. The study did not measure pain, mood or any other outcome for the volunteers.

Does 174 Hz relieve pain?

No trial has tested 174 Hz for pain. It is still the main claim on most 174 Hz charts.

Music does ease pain. In a 2016 meta-analysis of 97 trials, it lowered pain by about 1.1 points on a 0 to 10 scale. After surgery it reduced both pain and painkiller use, according to a 2015 Lancet review of 73 trials. In chronic pain, a 2017 review of 14 trials found a larger effect when patients chose the music themselves. None of these isolated a single pitch.

Research on low-frequency sound and pain uses lower frequencies. A 2015 study gave 19 women with fibromyalgia 40 Hz sound through transducers in a bed, 10 sessions over 5 weeks. Fibromyalgia, sleep and pain-disability scores improved, but the study had no control group, so expectation and time cannot be ruled out.

Binaural beats for pain were reviewed in 2024 across 16 trials. Most carried a high risk of bias, the evidence quality was low to very low, and the results were too varied to pool.

An older version of this page cited a 2022 study as support. That trial tested electrical stimulation of spinal nerve roots through an implanted device at 20 to 80 Hz. It involved no sound. Its only overlap with audio tones is the unit, hertz.

For nitric oxide, the closest study is about humming. In 2002, humming raised nasal nitric oxide 15-fold in 10 people. The rise came from air moving through the sinuses during the hum. Listening to a tone does not move that air. Cymatics images, where sound shapes sand or water into patterns, appear at many frequencies. They show how a plate or a water surface vibrates and say nothing about cells.

Pain that lasts, worsens or follows an injury needs a clinician. A 174 Hz track can sit alongside care but does not replace it.

Does 174 Hz help sleep?

One study used 174 Hz, and it tested a binaural beat. The evidence for music in general is stronger. A 2022 Cochrane review of 13 trials covered 1,007 adults with insomnia. Listening to recorded music for 25 to 60 minutes a day improved self-rated sleep quality, with moderate certainty. Sleep-lab measures showed no reliable gain. No trial reported harm.

A calm 174 Hz track at bedtime may help in the same way other calm music helps. Nothing shows the pitch is the reason. Raise ongoing insomnia with a doctor.

Stress and the "nervous system reset" claim

"Nervous system reset" has no medical meaning, and no study links 174 Hz to the parasympathetic nervous system.

Music therapy does lower anxiety. A 2025 meta-analysis of 51 trials found a medium effect on self-reported anxiety (g = 0.41). The effect on physiological measures was small and could be chance (g = 0.15). Any calm felt while listening fits that research on music. Body-level claims for 174 Hz, including lower cortisol, are untested.

What chakra is 174 Hz?

Charts disagree. Most modern charts start the seven chakra tones at 396 Hz for the root chakra and leave 174 Hz without a chakra. The Freqro healing frequencies list follows that convention. Some sellers pair 174 Hz with the root chakra or call it a foundation tone below the root. The chakra system is a spiritual model with nothing to measure, so no study can settle it. The Freqro chakra frequency chart sets out the usual pairings.

174 Hz benefits and risks

Volume and listening time carry the risk, whatever the pitch. The WHO puts safe listening at 80 dB for up to 40 hours a week. At 90 dB the safe time drops to about 4 hours. Keep the device at 60% volume or lower.

Low pitches sound softer to the ear than mid pitches at the same level, which invites turning them up. Stop if ringing, dizziness, headache or ear fullness appears. Binaural beats are not for driving or operating machinery. Anyone with tinnitus or hearing loss should ask an audiologist before using tones through headphones.

No side effects of 174 Hz are reported in people, since no trial has tested it for health.

How to listen to 174 Hz

Pick the format first. A pure tone, music built around 174 Hz and a binaural beat are different sounds, and only binaural beats need headphones.

Standard earbuds reproduce 174 Hz well. Small phone speakers reproduce it weakly, so headphones or a larger speaker give a cleaner tone. The Freqro guide to headphones for binaural beats compares options.

Sessions in the music and sleep trials ran 25 to 60 minutes. No study sets a dose for 174 Hz.

For a personal check, rate sleep or tension each day for one week with 174 Hz, then for one week with other calm music. If both weeks look the same, the music, the quiet and the routine are doing the work. The result applies to one person only.

174 Hz vs other Solfeggio frequencies

Each tone on the chart carries its own claims. The table sets them against the research covered in each Freqro guide.

174 Hz frequency FAQ

What does 174 Hz do?

It produces a low hum near the note F3. Beyond hearing, no study shows a health effect in people. Wellness sites market it for calm, and calm music does help many people relax.

Does 174 Hz actually work?

For pain, healing and inflammation, no evidence shows it. For relaxation, calm music helps many people, and a 174 Hz track is one option among many.

What is 174 Hz good for?

On the chart, pain relief, grounding and a sense of security. In research, nothing specific to the pitch. It suits meditation or a wind-down routine as a steady background sound.

Is 174 Hz good for sleep?

One 2026 study of 20 students found deeper sleep with a delta binaural beat built on a 174 Hz tone. The beat was the variable tested, and the study was small.

Can 174 Hz relieve pain?

No 174 Hz trial exists. Music in general lowers pain modestly in trials, and the pitch has never been isolated.

Does 174 Hz reduce inflammation or cortisol?

No study measures either after 174 Hz.

Does 174 Hz have sexual benefits?

No study tests it. Sexual problems that persist often have medical causes worth checking with a doctor.

What are the negative effects of 174 Hz?

None are reported, since no health trial exists. Loud volume can damage hearing at any pitch. A 2026 fish embryo study found no harm at 174 Hz.

What note is 174 Hz?

F3, about 6 cents flat in A = 440 tuning.

What are 174 Hz tuning fork benefits?

Untested. The only 174 Hz fork study measured whether practitioners agree, and agreement was poor.

Is 174 Hz the same as 174 MHz?

No. 174 MHz is a radio frequency, 1 million times higher and far beyond hearing.

What is the difference between 174 Hz and 528 Hz?

174 Hz is the lowest chart tone, listed for pain and grounding. 528 Hz is listed for love and transformation and has a few small studies. Neither has evidence as a medical treatment.
