It horrifies me to remember that computer operators didn't have ear protectors in the 1960s. Cabinet cooling fans; exchangeable disk drives; tape decks; card and papertape readers; card and papertape punches. Especially line printers with the hood open as you set the alignment and hammers etc for the next set of stationery.
It was quite interesting at the end of the Sunday overtime shift to hear how impressive silence was with everything powered down. Nowadays I have a permanent 8KHz tinnitus.
