All of you complaining need to ask your boss if you can move your desk/cubicle to an unused storeroom or basement somewhere where you can be totally alone. I never heard of such BS!
You work in an office with other people. You can't expect them to always be the way YOU want them to be, ADAPT! Get over it! Either that, or become a consultant and telecommute. Poor mistreated babies, sitting in an air-conditioned office on your butts all day, you have it oh so rough, having to listen to the noise fellow humans make in the process of living their lives in the same space as you.
We "IT professionals" are often considered by a lot of people as choosing our careers because we are introverted or anti-social, and use our skills to shroud ouselves in an aura of superior knowledge so others will keep their distance. Your complaints only add fuel to that fire.
Everyone (I would hope, anyway) reading this forum knows the truth - that we simply like our jobs - either for the mental challenges it offers or because we are die-hard 'gear-heads' and like to mess around with complex 'toys' to see what makes them tick (me).
There is no such thing as a serenely quiet office. Copy machines, phones ringing, people discussing projects, talking on the phone, doors slamming, come on, learn to live with it. If you can't handle it, become a forest ranger.
If someone is eating pistachios near you, ask them if you can have some, saying "they really sound delicious." You can catch more flies with sugar than with vinegar - just do your job & get along.
If a bit of noise is enough to make you flip out, then you need to get more sleep at night or do something to vent off some of your tension. If the noise really bothers you that much, wear some of those airline 'ear plugs'. If you can afford them, buy a pair of Bose ANR headphones. If your boss accuses you of listening to music (if that's not permitted in your office), tell him/her why you are wearing them (without pointing any fingers at any of your co-workers). But the first time you don't respond to someone calling your name for something important because you are aurally isolated, be prepared for the flack.
As for the person who obscenely yelled about someone clippping their fingernails, where I work, they would first be reprimanded (at the very least) for using language like that and secondly, made to appologize to whoever they shouted at.
Like Otis Redding said, "Try a little tolerance". Heheheheh...
