Do artillery shells really make a high pitched noise when they come in?

Modren artillery shells travel at supersonic speeds.  If you heard it - it missed.\n\nBTW, in real life you only hear a rocket or mortar round for about 1/2 second.  Then it has either flown past you or you have had a very loud noise closer to you than you'd really prefer.

They are about as loud as a .22 caliber. As long as it's not repetitive, no hearing loss should be a result. The DH and I shoot pistols/rifles every week at the club, but of course hearing protection is involved. I ran track in H.S., but don't even recall being startled by the starter (lol).

It is fairly easy to silence a firearm but understand you can truly only silence a bullet that is traveling less than the speed of sound.  Any bullet traveling faster than that has it's own sonic boom which sounds like a crack down range.  That you cannot silence.  Sub-sonic cartridges are designed for slower velocities which will allow for true silencing.  At sea level, I believe the speed of sound to be around 750 miles per hour which translates to ~1100 feet per second.  The rest of the answers are true enough... just like adding a muffler.

a little difficult to put a silencer on napalm or scatterbombs ,the screams of the dying would be heard anyhow.\nor try putting a silencer on a howitzer,\n\nand who needs to be saved ,the guys dropping the bombs are far away from the action.\non close combat you dont have to worry they got silencers on automatic hand guns

LOL!  It does indeed!  It's surrounded by air.  Sound waves travel through air.

Yes.. Modtones.com has it.. and I believe that Ringster.com might have it as well\n\nKill!\n\nSemper Fi!\n\nCpl. Howitzer

blackpowder or gunpowder exploding makes the cracle sound. they just put it in smaller sections so it wont be as loud

200 Hertz or any integer multiple thereof.\nSo, 400 Hertz, 600 Hz, etc.. would cause it to resonate.

They let out a VERY high pitched "squeak"...the sound of it echoes off of whatever objects are around them and they find their way through caves and stuff by the sounds they hear.  Hard to explain...I'll let someone else explain it in more detail.

Sounds like termites to me

the reason your ears rang when you shot the gun was maybe you had a ear infection

mortar shell will not be hot fo the following reasons.\n1.the barrel is short and smoothand the shape of the shell dosent allow it to touch the barrel much,so,the friction is minimal.\n2.the cartridge that propell the shell is small and there are normally rubber or fabric rings that dont permit the propelling gas toescape ahead of the shell to obtain the max thrust.\n3.the speed of the shell is not high to the extant that the friction with the air dosent heat it.\nbut its incedense with the ground may generate some heat if the ground is solid.but mind you ,if it falls on you ,it will kill you even if it dosent exploade.

it is just different times that each base goes by. One base may play it cause of cerfew for noise. I ve been to a few dif. bases and that what was explained to me.

i once read an article on weapons using noise to cause feelings of nausea and lightheadedness, along with extreme confusion.  theres the flashbang grenade, which doesnt explode but uses  ultrasound to violently shake the water in the eardrum, causing dizziness.  Then theres the highly experimental ring-vortex cannon, which fires a circular sound wave extrememly fast,knocking back adults, but can break bones and cause complete deafness.  But lethal, other than the cannon, i dont think there is anything like that yet.

what is your point (Loudest)?? I am under the impression that a 12 gauge shot sound would be the same if you fired a slug or buckshot..or bird shot for that matter..Wouldn't the sound be determined by the amount/weight of the load..and commerically I think they are all the same for the type of round you get..Good question..maybe I'll got out today and see which of the 3 types of shots are the loudest..Good Luck

Yes they do while your 1st burst will go okay there is good possibility of a jam on the next burst our 20mm phalanx gun did this several times much to the captains annoyance. The gun was brand new. Clearing a jam is a long messy maneuver as usually the feeder gears cut the shell casing of the jammed round. it's weird the gun will go several months without problem then it starts up again then goes away. Reloading these beasts isn't fun neither but until that new metal storm gun comes along this is the only weapon that fires this fast this accurately.
