People become accustomed to smells and sounds. If a person is in a building with the smell of pickles, they won't notice the smell after a while, but if they leave the building, and then come back inside, the pickle smell will hit them again. Some sounds disappear into the background in a similar way, although if you try, you can still pick them out. The sound of the fan on your computer, for example, had probably faded into the background until you read this sentence. I should also put in here that moving objects catch your eye among a bunch of still objects. I believe animals brains are well suited to notice change.
