Since the level of sound/noise is so important, to me anyway, I was wondering why that, along with that standard IBO/AMO speeds, can't noise level of a particular bow be measured. It wouldn't be that hard to do. I have seen some comparisons between bows and this has been measured. It would just take a set standard when the bow is tested for the speed all with bare bow have a decibel meter at a certain point/distance from the bow. Maybe somewhere somebody already does this, but to me noise level is as important as speed.
