The “432 Hz vs. 440 Hz” conspiracy theory

We know our bodies do follow circadian rhythms, so you have the initial link to length of day. Then everything else is split into sets of 12, a number with exceptional properties that natural selection may optimize towards:

"The number twelve, a superior highly composite number, is the smallest number with four non-trivial factors (2, 3, 4, 6), and the smallest to include as factors all four numbers (1 to 4) within the subitizing range. As a result of this increased factorability of the radix and its divisibility by a wide range of the most elemental numbers (whereas ten has only two non-trivial factors: 2 and 5, and not 3, 4, or 6), duodecimal representations fit more easily than decimal ones into many common patterns, as evidenced by the higher regularity observable in the duodecimal multiplication table. As a result, duodecimal has been described as the optimal number system.[4]"

Edit:

Another thing is that our current system of setting the duration of a second as a constant may be non-optimal for some purposes. Other systems let the length of time units vary with the seasons. It is interesting to think that under these systems, by maintaining the same base frequency, the tone of the note would change over the course of the year and with latitude. https://en.wikipedia.org/wiki/Roman_timekeeping

While I appreciate Jakub’s breakdown for the reader to get to explaining why the 432 number itself is effectively fabricated for convenience, he eventually states: “_The 432 Hz tuning, the divine tuning of nature itself, is ultimately defined as one vibration per 21279240.2083 periods of radiation of an uncommon chemical element_” however he’s missing the critical argument.

What is missing from the argument is the irrelevance of the number. For example, if 432 Hz resonates with I don’t know, the neocortex, there is no relevance what the number is or that we’ve associated with what we humans currently call a time second — that’s just a standard way of identifying the number.

What needs to be done is validation or invalidation of this frequency in terms of “healing and soothing properties.” It’s also important to not do so defensively, otherwise you’re arguing against organized religion or Santa Claus or Unicorns — it’s a useless effort to argue against something that has no scientific evidence. If someone is making a claim without evidence in the first place, you’re arguing irrationally already and you’ve already lost. Reason requires logic.

“Here is my repeatable scientific evidence why I feel the world is flat” is different than “I have a feeling the reason the sky is blue is from unicorn tears — prove to me it’s not”.

It is my suggestion that if someone feels that 432 Hz has healing and soothing properties, they take this hypothesis and run it through the scientific method. It will be these published results that can be responded to, directly. A quick search on plosone doesn’t show that there’s any documented research in this area currently, a new opportunity for those interested.
