Metrics.
Not Magic.

We measure, test, and cite primary sources on frequency therapies, binaural beats, and sonic hardware. Cut through the mysticism with lab-verified data.

The Problem with "Healing Frequencies"

The internet is saturated with claims that 528 Hz repairs DNA or that 432 Hz aligns with the universe's heartbeat. These claims often rely on numerology, misinterpreted studies, or outright fabrication.

Hz Research Lab exists to separate measurable physiological responses (like auditory driving and vagal tone modulation) from pseudoscience.

Verified Protocols

Brainwave Entrainment

Auditory beats (binaural and isochronic) driving EEG changes. What the clinical trials actually say about delta and theta states.

432 Hz vs 440 Hz

A strict acoustical and historical breakdown of concert pitch. Separating the verified harmonic differences from the conspiracy theories.

Vagus Nerve Stimulation

How low-frequency sound (typically 30-120 Hz) applied directly to the body influences heart rate variability and parasympathetic tone.

Stop guessing your frequency offsets. Use our suite of client-side calculators for binaural beats, wavelength mapping, and safe exposure limits.

Access Toolkit

By The Numbers

We aggregate data from peer-reviewed acoustics and neurology journals. When a product claims "clinical results," we track down the sample size and P-value.

  • Clinical Trials Reviewed 142
  • Hardware Products Tested 38
  • Frequencies Mapped 108

"While binaural beats of 15 Hz increased auditory driving responses in the EEG, self-reported changes in vigilance were statistically insignificant compared to the control tone."

The Solfeggio Frequencies

A detailed historical and acoustical analysis of the six original and three modern Solfeggio frequencies. We trace their origins from Gregorian chants to Dr. Joseph Puleo's numerology, and examine what modern research actually says about their effects.

Acoustic Terminology

Isochronic Tones

Regular beats of a single tone that are turned on and off rapidly. Elicits strong auditory evoked potentials.

Binaural Beats

An auditory illusion perceived when two different pure-tone sine waves are heard dichotically (one in each ear).

Resonance

The phenomenon where an object vibrates with maximum amplitude at specific frequencies (its natural frequencies).

Cymatics

The study of visible sound and vibration, typically via modal phenomena on plates or membranes.
