I never knew how much noise the AC made in my office until I got noise cancelling headsets. After my first week of using them I noticed how loud the HVAC fans really are. One thing I did notice was I have to pop my ears when I have the noise cancelling on. A few times it also made me feel nauseous when I turned them on.
