conspiracy theories aside, tuning to 432 does give each tone an whole number frequency all the way down to 54hz, this is mathematically significant.
However, this is where the significance ends, given that noise & sounds were around long before man was around to hear them or create them. The vast majority of these natural sounds are far more likely to be any frequency other than a whole number frequency. its just statistics, there's an infinite number of decimals between 100hz & 101hz, you are far more likely to hit a frequency in between 100 & 101.
As for the conspiracy stuff, i cant comment, I'm a massive cynic about anything that is not supported by recorded evidence.
