The brain serves us well. For example, you don't feel your clothing touching your skin all throughout the day, and you probably didn't notice until I just brought it up. Yet, now that I did, you notice. If you noticed things like that all the time (that is to say, if the brain didn't filter and attenuate chronic auditory and tactile stimuli), it'd be sensory overload. We'd all lose our damn minds.
