Bill, I was speaking of what I could hear on the phone in my home, not
on the floor of the C.O. ;-)
No doubt on the floor of the C.O. a 1(A)ESS was almost silent,
especially compared to SxS or even 5XBAR.

Sam,
It was a joke. J-O-K-E. Therapy for the humor-impaired, if you will.

Interestingly enough, there was a way to "silence" the #1A switch,
from the user's perspective (as opposed to within the office...) .
The original service trial for cellular telephone run by the Bell
System in Chicago used a #1 ESS as the Mobile Telephone Switching
Office (the 1A used the same switching network, but upgraded the
processor...). The "click" the user heard when the switching path
changed was obviously intolerable for cellular service as the cell
sites (and associated trunking) had to be switched as a vehicle moved
between cell service areas. There was an added circuit to the trunks
that, in fact, made the switching fabric "silent" to the users during
a handoff.
After the service trial, and before commercial service, the switch was
upgraded to a #5ESS and the extra trunk circuitry, to the best of my
knowledge, was never used again.

What about the noise you get when you pull out a Group Selector in an old
SxS switch and accidentally brush the power contacts in the frame causing
an ongoing arc across them.....
Whoops, I think I've said too much.....

Bill claims now he wasn't talking about actually being in the C.O. He
apparently has the ability to hear all that stuff over the phone.
***** Moderator's Note *****
No, I didn't, and I actually did work in a CO that had Panel, #5XB,
and 1AESS.
<humor>
My previous remark was meant to clarify that it doesn't matter if
people heard the sounds made by an ESS in person or on the wire: I was
making a point about how Real Men[tm] weren't bothered by minor
annoyances, because they had worked inside the boiler factory and
didn't think that hearing the noise of a loose pipe at home was that
big a deal.
