Do string silencers REALLY make a difference?

Like Zmonster, I've found that if the arrow weight reaches a certain point, it pretty much takes care of bow noise. But that "magic" weight may be more than the shooter wants or needs and then some sort of silencer can make the difference.

Made an interesting discovery this week.  I was shooting a bow that I had not shot for several years and noticed a "buzzing" sound on every shot.  Upon investigation I discovered the source.  It was the beaver ball silencers.  They had dried out while the bow was in storage and were not tight around the string anymore.  Took them off and replaced with cat whiskers and it is as quiet as it ever was.
