Global voice commands / Increase rolloff or volume for voice commands

I notice that Killing Floor 2 handles it's voice commands with local sounds as opposed to global sounds from the original Killing Floor. While I think this is a nice touch, it also implements volume issues as most of the sounds are inaudible most of the time. It can be awkward seeing them pop up in the chat log with no context. As global sounds might be undesired or annoying, I figure this can be resolvable with a higher rolloff (sound travels further) or volume increase. They are extremely hard to hear, especially under gunfire and other background noises. It also might be a good idea to stop it from logging since it's a bit strange having the text global, and the sound not.
