Speed of Sound

lucky strike · Post by **lucky strike** » Thu Feb 26, 2009 7:28 am

Sitting around with my morning coffee and day dreaming about the last hunt. I got a thougt!-If the speed of sound is apprx 1100 fps, what difference does it make on how loud or noisy your x bow is. The sound got to the deer about 4x faster than your arrow!So all the noise supression devices and silencers to my way of thinking only cut down the sound for the shooter and not the game.I don't hold the title of genious. So,does anyone have any comments on the subject?

I was going to put a spankin on an old doe last year with my rifle. She was only about 75 yards away and it was one of those cool, calm, quiet mornings but when I flipped the safety off, she flew as if I had already pulled the trigger. So, my point is, I don't think that there is anything that you can do to make a difference as far as what the deer can and cannot hear. I think that those who choose to use noise and vibration dampening devices on their bows do so because these effects bother them, (the shooter) not so much the game that they pursue. Just my view from up here in the cheap seats.

To avoid 'string jump' shoot at deer while they are calm and unaware. I look for those carrying a bong pipe.

I have mentioned it on other threads of a similar topic.

There is a sound suppression device that absolutely will work.

It's very inexpensive too. It's a shaped foam plastic or rubber material. Actually, two are required.

You put one in each of the deer's ears.

We are going at this the wrong way . . . .

We can't slow down sound . . .however, we can slow down our arrows. Therefore, if we slow them down enough, then by the time the arrow arrives, the deer would have went back to grazing and no longer alert. Thus no string jump.

"String jump" is an over rated excuse for missing.

There was a video done many years back by Drury Outdoors, which showed the reaction of a deer when an arrow was fired from a bow and why you should aim low. I believe it proved that a deer could drop as much as 18 inches [and I could be wrong in the inches dropped] in the process of getting out of the area. I remember they also showed it in slow motion. They also had the same thing happen with an elk and then repeated the process on a second elk.

It's true that cutting our crossbow noise by about 50% with various modifications will not keep the remaining sound from reaching deer's ears before the bolt arrives. However, a softer, dampened sound should up the percentage of deer that don't react as panicy as immediately lowering their body and bolting. More may just lift their head and look curiously towards what they heard as the bolt reaches them. Regardless of the deer reaction that occurs at the shot, it is wise to aim for the lower half of the kill zone. If possible in your area, another solution is to setup to hunt where there is alot of backgound noise to fill the deer's ears to cover-up all or most of your shot sound. Two common examples of such areas are along interstate highways or nearby major airports. Deer in those locales are used to the constant loud noise. (The only negative in hunting there is that deer calls and rattling can't be used very effectively.)

Guys,

I have never had a deer "jump the sring" me that I know of.

I've killed my fair share at ranges of straight down to 42 yards. None moved until the arrow hit them.

A "wired deer" might move, but a calm one wont.

i posted this earlier

for kicks i figured out that sound will travel 30 yds in .08 hundreths of a second.

depending on a speed of 300-350fps, the sound of the shot will reach an animal .18 to .22 hundreths of a second before the arrow does which basically means at 30yds, an animal has about 2 tenths of a second to clear out of the way.

i seen that episode and the your right the deer dropped 18 inches in .3 seconds at 30 yards i believe
