Sorry no-one has come back yet - I have been thinking about this as my sympathies lie on both sides of the question.
It is important to learn how to concentrate while noise or distractions are going on around you. Equally it is valuable to know how to concentrate when everything is quiet.
As to your son, some kind of "white noise" = a radio tuned to something he does not want to listen to, played fairly softly, might be a way of starting him off. The essential thing is to avoid things that will draw his attention from what he is supposed to do.
