Great video. I personally have never had a deer jump any crossbow I have used. When the bow is going of next to your head it does seem loud BUT down range it is a whole different story. I am more concerned with the noise made by my safety than the actual shot!

 

I see and hear as you noted the difference in the noise level. Quite noticeable at the target area. Although I feel the deer had no hope of escaping the shaft. That is neat and I will have to try this my self from out in the back yard on the ground sometime. To hot to be outside right now. I feel sorry for all the critters in the really hot weather. We have been in 100 degree range and way over for weeks now.

I feel as if my Parker Cyclone is really quiet, but one needs to listen to a video to really hear the truth. At long range shots, this is really something to consider. I feel confident at 60 yds with my set up, but it has a lot to do with the deer's attitude at the shot time. A calm deer is a yes, but a nervous deer at 50 - 60 yds is a no no. Only brings heart ache and lost sleep. I respect the animals as well.

 

I keep my shots to 30-35 yards. As the shots get longer noise could be a factor. I personally have never had it be an issue at the distances I choose to shoot.

 

Great video.

 

I have heard the deer here the arrow noise (the fsssppsss the vanes/feathers make) more than they here the sound of the weapon? You reckon there is much truth in that?

In my mind it is a combonation of both. I have seen some incredible footage of deer ducking at the shot so either or its amazing to see. Just aim a little low is what has worked well for me.

I shot some video from the target's perspective, and then slowed it down to emphasize the sound of various fletchings. I never did any tests with different broadheads, but I'm sure that they add to the equation as well.

Turn your volume all the way up!

 

I know these things are fast...and while the noise of the shot is louder to the shooter than to the deer, do not be fooled into thinking that a deer can not jump the string when a crossbow is shot. Unless your crossbow can outshoot the speed of sound (roughly 1125 fps)...the sound will reach the deer before the arrow does. The state of the deer has a lot to do with wheter or not he/she drops when the arrow is released.

 

I have found the closer the deer is to a sound the faster he reacts . At 20 yds a deer can easily duck an arrow if he is scared by the sound of the bow but this usually only occurs if he's alerted by something or something has him spooked. On the other hand if the deer hears a noise at say 60yds he is more than likely look to varify the possible spot of danger before he reacts. Atleast thats been the case when I have encounters with most deer over the past 30 some years. Rick

 

Where's the link to the video?

 

When I am bowhunting (28 yrs) I want my weapon as quiet
as possible.

 

I still don't see the link to the video that Old Hoosier is talking about. I do see one from Old Longhair.

 

One of the key factors this video is providing is that the larger the height and length of a given vane, the more noise it will generate because the more drag it creates to stabilize the arrow shaft.

The sound can be reduced by keeping your vane height to a lower profile vane and also by keeping your vane size down to a minimum length. This will increase velocity slightly while also reducing the sound by some percentage. Beyond doing this, the rest is not within the shooters span of control, since maintaining good arrow stabilization during flight is far more important than a little sound.

Consider the fact that vertical compound bows are also shooting at easily 325+ fps these days. They are producing almost as much sound on their arrows as crossbows are and it hasn't effected their ability to take deer to a negative degree. My compound is rated at 343 fps. but that's an IBO rating and not realistic when shooting normal length arrows and hunting shaft weights.

Another contributing factor to the shooter's perception of noise, is that unlike a vertical bow, you're making much more contact with the bow, and the result is a greater awareness of vibration. If you had both hands and your face making contact with a vertical bow, it would seem louder too.

 

After about ten deer with my crossbow I quit even thinking about the noise, concentrating on the demeanor of the deer and shot placement,Never shooting when questioning the shot, now at over fifty deer, As stated in previous post have never had a deer ,Jump the string. Have I missed with a shot,?you bet, Always shooting low for a heart shot.

 

After taking down 11 deer with my crossbow, I do not give a thought to noise. Never had a deer jump out of the way.

Sherwood...welcome back!!!!

Go to the "Crossbow Target Shooting Room". It is the second one after "General Crossbow Discussion" where you are now. Look for the title: "Shooting my Crossbow From a Treestand for the First Time". Click on the picture to watch the video.

Take no offense ppl. but after killin couple dump truck loads of deer without any noise reduction equipment & receiveing no complaints from any of them i killed. I have bought a new much louder noise maker & not only that its wingspan surely should knock down near by trees as i move in my tree stand. Wahoo come on new season!

 

Interesting but, the noise is being measure by OUR ears, not deer's. Moreover, we have not established that said noise bothers relaxed deer,
The deer in my avatar only looked up - after the arrow had hit - when I shot at the target just 15 ft from her. Bow noise or the absence thereof is a big issue for some, apparently because they think they will get a second shot. I don't. Shoot well, at relaxed and reasonably close deer.

 

When the camera is right by the shooter, you hear the twang of the string oscillating. When the camera is by the target, you can hear the crossbow go off but the sound is negligible compared to the ambient noise. What I found to be louder were the arrows whistling to the target. The thing we have to remember is that we were listening for the crossbow to go off. If the arrows were quieter and you were listening with your eyes closed, would you necessarily know that it was a crossbow going off?

This may shed some more light on what you're thinking.

How Well Do Deer Hear You?
Hunters Must Have a Knowledge of Deer's Auditory Range for Sucess.
Aug 18, 2008 Trevor J. Ballard
A successful hunter must have an understanding of a deer's hearing range. The type of sounds you are making while hunting are more important that the volume.


In hunting camps everywhere stories abound about the almost supernatural hearing ability deer have. Invariably there will be tall tales about a hunter missing an opportunity at a big buck because they were busted by the buck's keen ears. Deer being spooked by the safety of a weapon being clicked off or the sound of an arrow dragging across an arrow rest are some of the usual suspects in these campfire stories of blown opportunities.
Although some of these accounts of a deer's incredible hearing ability may have some validity, more likely than not a spooked deer is a result of several other factors above and beyond the hunter being heard by the deer. Knowing how well a deer can hear, but more importantly what type of sounds to make while hunting will help stack the deck in your favor the next time you go head to head or rather ear to ear with a whitetail.
Deer Hearing Sensitivity Research
In 1997 a study conducted by Dr. Ken Risenhoover at Texas A&M University, set out to define the hearing range of the whitetail deer. Using anesthesticized whitetail deer Dr. Risenhoover and his team attempted to define a deer's hearing range by attaching sensors to certain parts of the deer's head and interpreting the electrical responses obtained when sounds at different decibels and frequencies were introduced into the deer's ears. What this study discovered is that, based on the electrical responses, a deer's average hearing range is between 0.5 KHz and 16 KHz depending on the decibel level, with the maximum sensitivity in the 1 to 8 KHz range. That being said how does this hearing range compare to humans?
Human Hearing Sensitivity
C.R. Nave with Georgia State University gives a brief synopsis of human hearing sensitivity in the 2005 Hyper Physics Concepts website page. In this synopsis it is stated that human hearing sensitivity is rated between .02 KHz to 20 KHz. It can be assumed that these numbers are a fairly accurate representation of the averages found in the human hearing range, because unlike with the deer, a human can provide feedback on what they hear. With a deer the numbers are a scientific "best guess" situation but are thought to be accurate.

When the camera is right by the shooter, you hear the twang of the string oscillating. When the camera is by the target, you can hear the crossbow go off but the sound is negligible compared to the ambient noise. What I found to be louder were the arrows whistling to the target.

If the arrows were quieter and you were listening with your eyes closed, would you necessarily know that it was a crossbow going off?

Precisely why I made my videos. That bow going off is like a twig snap 30+yds away, but the sound of that arrow lasts longer, and is getting closer FAST!
