I know colo where people wear the big airport looking headsets when they
are going back there for awhile. We're talking many hundred to thousands
of rack servers in a giant cement room. Sure you aren't going to die or
anything but, it ain't good for your ears either. If you have to scream
at the guy ten feet away it's probably loud enough to use some sort of
hearing protection. If you're back there for 20 minutes who cares.
Probably still isn't great for your ears but, whatever.
That's what made me wonder about the sound level in these old pictures
with people working at their desks calmly like they were in any old
office. I've been around similar gear one piece at a time and they were
pretty loud. Still the frequency of the sound is much lower though.
Might make it much easier to take. These small high rpm fans are
piercing.
The pitch plays a big part of it. I never got a headache in "big fan"
machine rooms, but I sometimes do in "hundreds of 1U machines" machine
rooms. It's not like it kills you...those are probably the same guys
who wear goggles to mow the lawn. (or their bosses are just that
paranoid) Having a headache is, for me at least, far preferable to
having sweaty hair and ears from wearing a headset.
With all those
729 magtape drives? Deafening. -Dave
Now days people often put on hearing
protection before for going into
the racks. I could never imagine sitting at a desk answering a
phone
among them.
That's just not possible. In some datacenters we had special phones
with high-volume headsets and focused microphones.
