>>11527045This is actually an interesting historical and linguistical question. If you go back and listen to old newsreels before the '70s, people's voices were much higher in timbre than they are today. Part of it is that reporters spoke higher, because of the limitations of sound recordings. But if you listen to ordinary people being interviewed, their voices are higher as well. Then, somewhere around the '80s, reporters' voices changed to a much lower timbre, because the tv and radio speakers could reproduce more bass. And for some reason, suddenly it was unmanly to speak in a higher voice.
Just check this clip of elderly people recorded in 1929 out on youtube. /watch?v=g9P2fuqoFec&ab_channel=ColorHistory
This is not just an american thing. It's the same all over the world.
