Title: That hornet buzz
Post by: kevinsmith5 on January 12, 2013, 09:23:22 pm
Every few shots my turkey feather fletched arrows make that buzz arrows always make in the movies. Not as loud, but its definitely there. At first I thought it was just one of the arrows but I have since figured out it happens with all of them at random intervals. The shots that buzz don't seem to fly any different them the ones that don't. What makes them make this sound at random intervals? Anyone?

are the bases of the feathers fully attached? if they are just tied by the ends then if it was loose it could make that sound i suppose.

Glued down and wrapped with artificial sinew at the fore and rear.

If the trailing end of the fletching comes to a point just cut about 1/4" of the point off and it should quiet them down.

Howdy,  My arrows do the same.   Part of it is the shape of the fletching.  I always have had the impression that the 'buzz' is heard on those shots with the cleanest release.   Yeah....I'm still working on my release.   Anyway I never hear the 'buzz' on shots that wobble, even the slightest bit.   Ron

When you  get old enough, your arrows will be very silent.  :)

Unfortunately I'm more worried about the deer.... :)

If you want the fletching to be silent ( as possible) follow the recommendations already made by others......make sure they are well attached and the the trailing corner of the fletching is rounded.    I suspect that a slow arrow is less likely to make noise, too.  But for hunting, you've probably already chosen to go with a heavier mass arrow.    Ron

They're 33 1/2" long 11/32nd spruce with 155 gr heads.already clipped the point from the trailing edge.

It's usually the shape of the fletch. The modern rounded fletch is quiet. It's part of the fletch that catches wind and flutters . I leave trailers on the front of the fletch on  my practice arrows ,just because it makes that sound everyone likes to hear.

Figure out how fast your arrows are travelling.  Let's say 150 fps, just a round number to work with.  Ok, and your deer is at 20 yards, that's 60 ft. 

60/150 = 4/10ths of a second. 

That's how long the arrow is in flight between leaving the string and hitting the target.  Actually, since the arrow is slowing due to the effect of drag on the surface area, a bit more, but 4/10ths is a pretty easy number to work with. 

By the time the deer has heard the sound, processed the sound, and has fired off messages to the muscles, and the muscles have begun to respond, the arrow has already arrived.  Almost every video I have ever seen of a deer "jumping the string" has the deer moving before the release.   In one, the deer actually drops AFTER the arrow pass! 

The real trick is not letting the deer see you drawing!  Or pick dumb deer.  I prefer dumb deer. 

Go thru your arrows one at a time.  Pull on each of the feathers, front, middle, back.  I always seem to find areas where the glue loosened up somewhere on a fletch and is the buzz culprit.  If they are all nice and tight, then try rounding off the backs of the fletching, or even cut them down lower. 

As for target arrows, often I will leave the very back of the fletch high on purpose to make them do that lovely "Robin of Loxely" sound that the movie sound people are so fond of.  Now if I can just figure out how to make my bows do that cool leather creaking noise.  So far, the only sound I can make them do is the dreaded "tick....tick...BLAMMO-BABY!"

JW   You may be right about the videos, but the reaction time for a middle aged man (like myself) is  LITTLE LESS THAN 3/10 SEC.   For a healthy young man its often less than 2/10 sec.     So a deer is likely to have a reaction time 2/10 sec or less.   I'm just guessing about the deer, but the human figures are real.  That's just the time to receive process and begin physical reaction to a stimulus, but you can make your own conclusions.   Personally I think Kevin has a legitimate concern, though the sound of the string or the draw may be more likely to set off the deer.

I do most of my shooting at the range so I like the Hollywood type sound effects.            Ron

I believe that the deer are more likely reacting to the sound of the release. Arrow /string/shelf,etc. The sound from that will reach the deer before the arrow,or the sound that the arrow makes, unless your arrows are travelling faster than the speed of sound.Think about it the next time you shoot.Twang/thwack /thud (choose the sound that best represents the sound of your release)SSSSSSSSHHHHHHHHHHEEEEEEEEEWWWWW!!!!!!!!!!!!!!!!  Whack. Standing next to the target 25yds away (not recommended) ,you will here the same thing.

Well the speed of sound is 1,125FPS.  You must have some really fast bows to get the arrow there before the sound arrives and allow ANY deer to not hear and process it first.

   You can only here it from behind of if it pass's you. Comeing straight at the taraget it can't be heard.
  If it really a problem for you, don't cut your feathers above 1/2". Only traditional dose this. I think PAT side it cut off the back point of the feather. That will also get rid of it.
