the last 24 hours ive been hearing a beeping sound repeating in my head every other second. its based on an annoying beeping sound i heard regularely in a certain room in the place i work at. it was from a battery i think in a smoke detactor that was old and dying. they finally replaced it and the beeping noise is gone, but its been repeating in my head the last 24 hours and has been driving me up a wall. any help on what to do about this is urgently needed and appreciated.
