Sound Development

[Boumu 84]

This is kind of a difficult question to ask but I'll try to word it best as possible, so in every game I've played other player's voices are clear as always in every direction and even through walls. Will this be the same case as in Identity or will they have something like if two players are having a conversation someone on the other side of the wall can hear a very muffled version, will there be any changes in voice for people who swim, are in a sound studio, through radio? I want to know because I consider myself a sound whore and find myself so much more immersed just from sounds and  being able to hear the footsteps of others and which direction it is coming from 'n stuff like that

Sounds tricky to pull off, but then again they've already dedicated to using realistic ballistics. If walls can have properties like density, then I think it's possible for sound to play into it. But don't quote me >_>
