Possible unbalance in sound on E186 loco

[Wocka-Wocka]

Hi all.

I am no expert in locos, but after getting more and more hours into specific locos, I noticed that I try to "avoid driving some them" because of "the sound being hard to bear".

More specifically: The more I listen, I find specific sounds in E186 locomotives that "hurt" my ear.

Even more detailed:

• In E186-134 today I measured a high pitch tone (#A4) that was "pulsating"
• This sound is probably coming from the electric transformers from some kind of equipment in the cabin
  • nothing strange here
• If I turn the volume down, it is still there.
• If I turn down the volume a LOT, to the point where I almost can't hear "czubak" warning, or even that the train is moving:
  • Still hear a very clear A4-pitched sinus tone

 

So making this thread to discuss specifically about E186, and if there is a specific bug in the sound balance.

• Have anyone else experienced this in a E186? Can you hear the same thing I am hearing?
• Could this be caused by the balance of all sounds in the cabin "being wrong"?
• Is there a way of using software to fix this, without removing "realism"?
  • for example using a so called "compressor of sound"
  • include a debug mixer showing graphs of ALL the current sounds generated?

 

I am also starting this thread to get a first balanced discussion about sound, where we do not ALWAYS talk about CD163. 😁

Because maybe the problem with CD163 is just that the "CD163 IS a CD163"

And maybe this high pitched A4 tone is something that really IS overwhelming all other sounds in a real E186 cabin? Because then the "E186 is also just a E186" 🙂

In other words what I am talking about is IF there is a problem in the sound mixing. Not if the sounds are "annoying".

 

I love both E186, and CD163.. amazing engines, and I can't imagine that all drivers in the real world have this "sound problem"...

..so bug?  Or is my specific ears over-reacting?

 

/Wocka, with actual Tinnitus problem last couple of months, where the only high sounds I have experienced are running this game.

I couldn't find any audio sources bound to wrong mixer. Only sound looping no matter what when locomotive is idling, is PSM. Could you check sample in attachment if is it? @Wocka-Wocka

Thanks @Stele for posting an example file, and yes the sound is there.

However:  There are two sounds there, so hope we can isolate the EXACT one:

• one is ok, and has pitch about G5
• other one is around B6 (sixth octave on a piano) and is a very high sinus tone
  • if this is called PSM I do not know
  • I personally think this higher pitched one need to have lower volume
    • even on lower volume it will still be audible because of the high pitch, so I do not think realism will be affected

Also just tried another Traxx just now, and maybe I am imagining things, but I feel that this high pitch sinus tone is more loud the more sound the loco is making.

Trying to attach a short video, which maybe also helps show this high pitch tone coming from the engine room.

Attachment problems, seems h264 works, h265 does not

Since I started this thread I started to watch videos of cabin views from real locomotives

 

And I notice that the sound in general is much more "lower" from the engines and electrical equipment.

 @Mr Murphy posted a link to this video clip (in a different thread about Traxx) which "proves" we need to fix the "balance" between different sound sources in a cabin.

The in cab sound is much much softer than outside and that's caused by cab isolation materials. But not only - some equipments like cab air conditioning can't be hear outside. In SimRail's TRAXX (electric one) You can swap between cab view 1 and outer view 2 (as close to the cabin as possible) ... and there's almost no difference. The character of the sound should be completely different and this can't be achived by just manipulating outer sounds - cab sounds need to be recorded in-cab, separately! And I doubt they just didn't have enough access to those locomotives to record everything. That's why they started to manipulate and used replacement sound files (recorded outside). Anyway - both TRAXX loco sounds - electric and diesel need lot more work. Those are weakest in game. For example 36WE sounds almost perfect.
