Ever notice how noisy a workplace gets? I work in an office and I sometimes find it amazing how much noise we live with on a day to day basis. The excessive whine of 30+ computers struggling to stay cool and the groan of the air conditioning system keeping the air moving in the building is enough to drive one crazy. Add to that the fridge in the lunch room and the occasional fan pushing air and soon you can’t think straight.
Thankfully there is a solution to all this. Noice cancelling earphones. Luckly you can then pipe music into your ears or you would probably go crazy in the silence.
