by whom? the media they own, lmao
i seen the cell footage where the girl filming was talking about it.
he American music industry reached an informal standard of 440 Hz in 1926, and some began using it in instrument manufacturing. In 1936 the American Standards Association recommended that the A above middle C be tuned to 440 Hz.[4] This standard was taken up by the International Organization for Standardization in 1955 (reaffirmed by them in 1975) as ISO 16.[5]
they changed it to 440hz from 432hz to keep us in a state of perpetual agitated state.

propaganda and lies, programming the sheep the way they want, duh
