Noisy jobs? The current advice is to do them around them from birth so they get used to it. Babies aren't too bothered after a while. Mine tends to eventually sleep so deeply it wouldn't hear or feel anything. it's how we can transfer it to other rooms in the house without waking it. We have vacuumed around him from practically day one (well day 10 at least because we didn't have time to do housework the first 10 days).
The first two years of my life we lived in a house that wasn't much different from being outdoors. You know the old unpainted board houses on the old black and white cowboy movies? Anyway, to the point of this post, the house was under a railroad trestle and even as a baby we (including me as a baby) slept right through the train chugging past less than fifty feet away with the crossing whistle blaring. Babies do indeed get used to noise quickly. To this day I find the sound of a passing train has a calming effect.
