Custom Attenuation Sound
This will make interior sound more had a bass effects & more isolated.
ATTENTION !
maybe some of the existing sound mods will be weird if you combine them with this mod.
therefore you need to update the sound mod to the latest version + also need to change the sound configuration.
work on all default scs truck,rjl scania,eugene scania,daf schumi,mercedes schumi or truckmods with default scs definition
