On drum printers and punch card equipment...
Yes, drum printers can make LOTS of noise. One I worked with had all the characters lined up, so a row of say '$' characters would generate a big THUMP as they were printed (the operating system did this for the trailer page). The capacitor bank for this behemoth as about 1/2 Farad at 35 volts or so, and I'll let someone calculate the energy stored (bazzert is too mild). Eventually we swapped it out for a chain printer, and the line changed to "zing.." which was a bit easier on the ears.
As for punch cards, the reader was blissfully silent compared to the punch. Sometimes one would attempt to punch out "lace cards" and the racket was terrible (if it didn't jam in the process). Thankfully we didn't punch too many cards, except for keypunches (they are loud as well).
Ahhh, my youth.
