With regard to the volume I have to say a time. The manufacturer can though only the airborne sound - and then only in certain dimensions - affect something. For example, as the fan control.
For the structure-borne sound, the manufacturer can of course anything and that's why I want equal time to recommend rubber feet to buy, otherwise the vote is unfair.
5 stars because what more could you want?
