I was referring to the basic principals of function. A compound, regardless of configuration, will always be noisier due to having the weight of the pullies on the limb tips.
Yes, poundage is different, but so would a vertical be if it were <30" ATA with a 14" draw length to achive the same speed. If you're going to compare, then compare apples to apples.
Bottom line: A crossbow, to achive similar balistics to a vertical, will aways be noisier. It's one of the drawbacks of needing 175# draw weight to get 300fps+, because you only have a 14" draw length. It's also the reason for fixed trigger release.
(just try to draw and hold 175# @14" by hand

)
Some manufacturers are starting to make lower draw weight bows with longer power strokes to get the desired speed. Bullpup style and reverse limb technology bows make it possible, w/o adding length, so the bow isn't to un-weildy.
