Description

New in this version: Revised soundproofing for the Kenworth W900.
This mod brings back a similar soundproofing from 1.42 for ATS default trucks affected by the 1.43 interior cabin sound update.
With this mod you get a comfortable experience, with outside sounds including the engine more quiet when the windows are closed.
Features:
Stops in-cab sounds from being louder than when the camera is outside and next to the engine.

Reduces the excess reverb in the cabin.
Lowers sound volume of high pitch sounds such as turbo when windows are closed.
More Info:
You can enable this mod with low priority in the Mod Manager if you want.
Modders are welcome to use the baseline settings provided in this mod for sound_effects_units.sui
Tip: Do not stray too far in increasing gain values, because it may affect all sounds such as traffic and ambient sounds.
