ETS2 - Silent Turbo V1.0 (1.38.x)
This mod eliminates the annoying turbo sound from the original engine sounds. For some like me the frequency of this noise is way too high and ruins the gaming experience.
For this I silenced the specific turbo sound and edited the higher frequencies of the other engine sounds, where in some cases the turbo was still present.
Of course it works with the original sounds, not the other sound mods.
