Yes, but it was the card punches that really got the noise levels high!
We had a 2540 in our datacenter and thankfully didn't run the punch very often..but
when we did......wow!

fans whirling away, it was a deafening kind of quiet background noise,
I miss that.
The previous generation had lots of 7 and 9 track tape drives. The
vacuum pumps in those were anything but quiet, particularly if you
had 16 or 24 or more of the damned things. It was like a very loud
white noise (maybe 80 dB or so); you had to raise your voice above a
normal conversational level to be heard. Over an 8 hour session, you
felt that your nerves had been scrubbed raw.
Oddly enough, the CPU was quiet--it used water for the heat
exchanger; no air.
Printers and card readers could get to be loud, but they weren't
going all the time and the printers had acoustic hoods.
