The Solfeggio Frequencies Myth
Why 528Hz doesn't "repair DNA" and 432Hz isn't the "frequency of the universe."
A significant portion of consumer sound therapy is dominated by claims regarding specific, purportedly magical frequencies—most notably 432Hz and the "Solfeggio frequencies" (like 528Hz). These claims lack empirical backing.
The Origin of the Claim
The modern Solfeggio frequency claims largely originate from a 1999 self-published book. The numbers (396, 417, 528, 639, 741, 852) were derived using "Pythagorean skein" numerology on the Book of Numbers, not from acoustic physics or biology.
The "DNA Repair" Fallacy
Claims that 528Hz repairs DNA cite Dr. Leonard Horowitz, who in turn cited biochemical researcher Dr. Lee Lorenzen. However, no peer-reviewed biochemical paper exists demonstrating that an acoustic wave of 528Hz can structurally repair chromosomal damage. DNA repair is a complex enzymatic process (e.g., involving DNA ligase), not an acoustic resonance phenomenon.
What about 432Hz vs 440Hz?
440Hz is the ISO standard for concert pitch (A4). 432Hz is an alternative tuning. While some listeners report preferring the slightly lower pitch of 432Hz due to subjective aesthetics, there is zero clinical evidence that it is intrinsically more "healing" or biologically aligned.
