The Frequency Lab
432 Hz vs. 440 Hz Blind Challenge
Blind A/BFocused
Let the data speak — not the hype. Two versions of the same piece, tuned differently, labelled only A and B. You don't know which is which until after.
Primary benefit: Personal experience minus expectation bias.
Educational framing
Claims surrounding 432 Hz and 440 Hz are debated. This challenge does NOT state that one heals and the other harms. It's designed to explore personal experience while reducing expectation bias.Measurable
- • Randomized condition (A/B → 432/440 revealed after)
- • Heart rate when available
Self-Reported
- • Relaxation
- • Mood
- • Focus
- • Body sensations
- • Preference
- • Notes
Exploratory
- • Do your ratings differ between A and B?
- • Does preference align with the tuning claimed to be 'healing'? Data > hype.
