The 432 Hz tuning debate has raged for years. We put it to the test with actual measurements and blind listening tests.
The Claim
Proponents argue that 432 Hz is more natural and healing than the standard 440 Hz concert pitch.
Our Analysis
Using spectral analysis and double-blind testing with 40 participants, we found no statistically significant preference for either tuning.
What the Data Shows
The difference between 432 Hz and 440 Hz is approximately 31 cents, well below the threshold most people can reliably distinguish.
