The new sound attenuation/damping is great but far from perfect.

If you stand outside of a building or structure (f.e. container) and you throw/shoot a grenade or set off a satchel inside that building or structure, there is no sound attenuation. There are no hearable differences between explosions inside or outside buildings or structures.

It would be great if the developers add variety to all kind of explosions like you did with the weapon "tails".
