The “432 Hz vs. 440 Hz” conspiracy theory

Adam Neely has a great take on this: A = 432Hz https://youtu.be/EKTZ151yLnk

Another good one is Paul Davids: The Ultimate 432Hz VS 440Hz | CONSPIRACY + Comparison https://youtu.be/Rt3EAPDn-Ug

> At the urging of singers, the French government made the tuning A = 435 Hz officially standard in France in 1859

Did they know that the time that they had chosen exactly 435 Hz? That is, were they to directly count the number of waves per second using the technology available at that time?

My quick searching says that devices such as "Scheibler's Tonometer" did exist at the time. These allowed the user count the much slower "beats" between two tuning forks, letting them extrapolate the frequency of a unknown tuning fork from a known. But what did they use for a known?

Or was the French standard only actually defined as a particular tuning fork, only determined to be 435 Hz at some late time, when better technology was available?

> There are millions of people in the world who believe that Goebbels introduced the tuning to make people feel more anxious.

That's absurd.

It's more likely Goebbels did that to demonstrate that Germany was no longer bound to Article 282 (22) of the Treaty of Versailles, which forced it to accept the 435hz standard.

The average human alpha wave, the most dominant brainwave, is 10hz. Coincidental that 10 fit in a second, I guess.

Personally, I would prefer that seconds were slightly shorter (~.84 seconds), because then we could have decimal time, where there are 100 seconds in a minute, 100 minutes in an hour and 10 hours in a day. Mm, would be soo satisfying. Useless, but satisfying.

It was funny how the numerology is bunk but then we use 440 rather than 439 because it's prime. It all makes sense of course unless you're in the believer camp then it could seem arbitrary.

heh yeah, numerology doesn't make much sense when applied to measurement units generally. That hasn't stopped it being applied anyway. For someone already prone to this sort of thinking, they're looking at the number, without thinking about how the measurement base was derived.

Thankfully, this article isn't so much about debunking the exact myth, but rather the notion that the standard has any particular historical significance. It is interesting to think that it wasn't until recently we have even been able to reasonably measure and standardise frequency.

I found the article hyperbole and a better reference is scientific tuning [1]
