Refutation and method — what happens when you actually measure the claims behind frequency music.
- A Binaural Beat That Moves: Alpha Down to Theta Most binaural sessions hold one frequency for the whole runtime. This one descends from 10 Hz to 6 Hz across ninety minutes. Here is why, and what the evidence does and does not say. Read more →
- Green Noise Has No Standard Definition Green noise has no agreed acoustic definition and no direct studies. So we synthesized the most common interpretation and measured it. The most honest color of the set. Read more →
- White Noise: Masking, Not Magic White noise is the flat reference of the noise colors. Its most reliable benefit is masking, and the sleep evidence is thinner than the internet suggests. Read more →
- What a Hertz Actually Is, and Why Two Counts Disagree A hertz is one cycle per second. Build a 528 Hz tone in Python, then count it two independent ways: the answers differ in the last digit, and the reason is worth knowing. Read more →
- Pink Noise: Closed-Loop vs Continuous The famous pink-noise memory studies used precisely timed pulses, not a track playing all night. Why that distinction changes what continuous pink noise can claim. Read more →
- The Noise Label Problem A color-noise label is supposed to mean a specific measured slope. We measured popular tracks the way an instrument would. The labels often do not survive. Read more →
- Nothing Repeats: How You Check a Claim Like That Long sleep tracks are usually one short loop played many times. Ours is twenty-six separate passages. Here is the measurement that turns that from a claim into a result. Read more →
- How We FFT-Verify Every Session Most noise channels cannot tell you what you are actually hearing. We can, and we publish the proof. The synthesize-then-measure method, in plain terms. Read more →
- Same Note, Different Sound: The Measurement I Got Wrong First Three waveforms at 528 Hz measure the same note and sound nothing alike. Chasing the reason turned up a number that should not exist, and my first attempt to measure it was wrong. Read more →
- The Honest Version of a Dopamine Reset Dopamine reset is one of wellness's favorite phrases. We make no claim to measure or reset dopamine. Here is what a theta recovery session honestly does. Read more →
- The Ney Is Mostly Breath, and That Is the Point The Turkish ney keeps the player's breath in the tone instead of cleaning it out. Measured, it is the darkest instrument we have published, and the noise is doing real work. Read more →
- What a Nervous System Reset Actually Means Theta binaural is sold as a nervous-system reset. Here is what theta rhythms and heart-rate-variability research actually support, and where 6 Hz sits in that picture. Read more →
- Delta Waves and the NREM Problem Delta is the rhythm of deep sleep, so delta binaural should help you sleep deeper. The research runs into a specific problem in exactly that stage. Read more →
- 40 Hz Gamma for Focus: A Map of the Evidence 40 Hz gamma binaural has the strongest research base of any binaural claim, and it is still emerging. What the studies show, what they do not, and why headphones matter. Read more →
- 528 Hz: What the Evidence Actually Supports 528 Hz carries some of the biggest claims in frequency music. We separate the modern Solfeggio tone from the marketing and cite what actually holds up. Read more →
- 963 Hz Is Not Ancient. It Was Added in the 1990s. The 'ancient Solfeggio' story behind 963 Hz is not ancient at all. The nine-tone scale was assembled in the 1990s. What that means for the claims around it. Read more →
- White Noise for Baby Sleep: What the Evidence Shows A small trial settled most newborns in minutes with white noise. Frequency music for babies is a separate, weaker claim. Read more →
- Why the Armenian Duduk Sounds Warm The duduk's warmth is not only a feeling. Its spectrum has almost no high harmonics, and that is something you can measure. Read more →
- The 174 Hz Study That Does Not Exist A Harvard 174 Hz study gets cited across frequency marketing. It is not in any research database. Here is what is real about 174 Hz, and what is not. Read more →
- Brown Noise and Focus: What the Research Actually Shows Brown noise is everywhere in focus playlists. We measured its spectrum and read the actual studies. The slope checks out; the focus claims are thinner than the label suggests. Read more →
- Is 432 Hz actually 432 Hz? We measured. A lot of music is sold as 432 Hz. Before arguing about whether the tuning matters, it is worth checking a simpler thing: does the audio actually sit at 432 Hz? We ran the numbers. Read more →
