Not really germane to this forum, but I found an old Coyne Electronics School book from 1960, firmly in the slipstick era when I was growing up, that my manager at my first engineering job gave me back in 1982, lots of old schematics etc for 50s & 60s tube TVs and radios.
Anyway, the book has some stuff, like a nomogram for performing audio level conversions (which I have used more than once, pre-internet) and also a sound volume chart reference page with lots of info, like how many watts needed to fill a room in 1000s of cubic feet with "x" size of audience, coefficients of absorbtion of sound, yadda yadda yadda.
Figured some of yas might also find it interesting. I do, but I'm an old EE geek...
Hope ya enjoy this trip to the past...
