RE: Deer can hear arrow first? Not!
I like this thred. I just was thinking of the time elements involved.
250 fps for the arrow so time to impact at 20 yards is .24sec
The sound of the shot gets to the deer in .062937 sec
The time that the deer has to .177063 sec
Conduction time of nerves is approx 250mph or 366 ft per sec = .00546 sec
Process time in the brain for a deer can be as short as = .001sec.
Time to travel to the muscles at 366 ft/sec = .01092 sec
Total time untill the deer reacts from the sound of the shot = .15968
So how far can a deer move in .15968 sec? (at 300fps you can - .04 sec from this)
These figures include that the deer was aware at the sound of the shot. Not relaxed. IF the deer were relaxed I would think that you could subtract another .1 of a sec for the time that the deer became aware.
(by no means are these figures 100% accurate. I just did a little math on the spreadsheet)
