IMHO, the bowstring fiber that's got lotsa stretch/creep (i.e., Dacron B50/B500/etc) and is heavy in mass weight, will most likely be the dynamically quietest - but will also be poorer in performance whence compared to better more durable and higher tensile strength fibers.
In any event, a well placed set of good string silencers, plus using a 10GPI minimum arra weight, are the reasons to use a high performance HMPE string fiber (Dyneema, Vectran, etc) over the slower stuff. YMMV.
