Supressors and silencers are two different things. They do not make any gun quite, in fact they are used to keep the sound of the gun firing from damaging your ears by bringing it down to a safe level.

Please, if 70 meters to a pistol with suppressor is a safe distance or not? Besides I set them in the building!

You will hear a mechanical shutter sound even at a distance of 70m.

A suppressed 9mm is pretty loud. 125-130dB(A) is not what you'd call hearing safe (the definition makes you believe you can listen to suppressed shots without damage, which is wrong). You'd hear the shot in and around a building that is not soundproof. And there are no such buildings or bunkers in ArmA 3.

@ThePredator
I don't know where you get the info but I, I don't believe it. DO you know how can describe 130db? If a working jet engine has a noise of 120db, then a pistol with suppressor has a noise as 10 times as jet engine?

I get the info directly from the source: the gun. I work in the firearms industry. But even as an "outsider" you'll find a lot of sources for sound levels for suppressed weapons. For example, here is a review for several 9mm suppressors.

You could also look up suppressor manufacturers and use their "values" which are mostly enthusiastic than realistic.

Enemies can only hear suppressed weapons at those distances when the shots actually hits a soldier. If the shots don't connect, the enemy will not hear anything.

That does not make any sense, does it?

Selective hearing. "Oh, someone shot a weapon. It didn't hit anybody, so I just ignore the enemy presecne."

Good reply! I like it! It should be the origin issue not the sound aware the AI, but the dead body! If this proves right, then the AI has a magic X-RAY vision that cause problem anywhere.

You guys don't want ArmA3, you guys want a different game. Suppressors do not magically make enemies unaware of your position, even when you shoot them.

Of course the AI should also react to dead bodies, but this is another issue not only related to suppressed kills, which are not silent at all. You'd have to use a knife and some technique to stay covert. Or dedicated suppressed caliber & weapons, like .300AAC.

@mrflay: that's complete and utter bullshit. Sound waves are longitudinal waves of compressed air, meaning that unlike a laser, they'll reproduce spherically.

ThePredator is very right in almost anything he says. I do think suppressors are implemented horribly in ArmA 3 however. No subsonic ammunition and somehow the round magically becomes less potent with a suppressor. This is a major step backwards from ArmA 2 and one of the many areas where the developers completely f'ed up.

Yes, I know suppressors are not silencers. But even if you do make an actual silencer (or a completely silent weapon, eg. knife, bow, magic, whatever), the enemy will still know when his buddies are killed. It's how arma work, currently.

@ThePredator
One thing I really ignored that if I was the bluefor man, and I delet the opfor in the building, then I shoot the glasses of the building, the enemies outside never change any condition! So how do you explain? Why when there is no opfor in the building, the sound of breaking glassed by a same suppressor pistol won't make enemies outside alert?

@mrflay
You inspired me. Now I confirm it is not sound that cause the enemy group know the assasination in the building. If I am the bluefor and I kill the enemy one shot, then even I break every window of the building, the enemy wont change their safe condition. However if I kill the man by 2+ shots then they will change.
