Had the same problem on my first deer as well. Hit her high and lost her to another hunter the next day. After shooting multiple deer afterwards I have found the sound of the string to not make much of a difference if the deer is not looking at you. I believe they see the arrow and flinch, just like you would if you saw a baseball headed towards your face. Just make sure they are not looking at you when you release and that should help. The video shows all of the deer ducking so that may have been a reaction to another deer. I have taken lots of deer with my old, loud bow. Bow hunting is about knowing your prey and outsmarting them. Remain calm and place your shot. Good luck and go put one in the freezer.
