First, all arrows make noise in flight. Second, sound travels faster than any arrow.
First off let me say i DO NOT recommend doing this little test.
Last year at the archery range my buddy and i were wondering how much noise an deer hears as the arrow is flying its direction. Simple enough to figure this out. My buddy stood at about 40yds and i went and stood about 5yds to the side of the target. We tried a couple different styles of vanes and they ALL made comparable noise.
Not real loud but certainly alot more than i would have expected. The noise of the air rushing over the vanes created a noise similar to a jet taking off just not as loud. And yes the noise was there long before the arrow was.
