Depends on the 'noise' and what is producing it. Ideally you should 
first of all try to achieve the best signal:noise ratio for the signal 
you want to use to feed sigmund~. After which you might try some sort of 
gating, depending on the source type (you talk about silence so you 
could look at e.g. at [threshold~] or [env~]) and application.
