tank Tank Reloading Sound question.. plz help me!

[-SIS Simon Ghost Rilley 0]

Hello.
I want to keep the reload sound of the tank from outside. I have been looking for a way to do this for 5 months, but I could not find a solution because I am not good at English.

The current situation is where Leopard2's reloadsound from BWMOD can be heard from both inside and outside.
Other addons are not (e.g. RHS M1, T-Series, Arma3 Basic Tank etc..)
I want to find a solution to this problem. I checked to see if the Sound.cfg of the other addons was different, but I didn't see any difference.

There are many experts here, so I ask you a question. Please help me.

What I want: (Reload Sound will not be heard from outside (3 person)
