Please note, as it was mentioned before, the bell is used for various other features around the world, including a second horn sound. So its volume cannot be lowered.

Talking about the horn sound, again, it's not the volume might be wrong, but in reality the horn is a directional sound, directed forwards, while in OR it sounds all around. That's why the difference.

Alright fair enough, then. What of the Low Pass filter application to #5 view sounds?

That's a clear example of how position wrt the sound source, environment etc. can influence the sound in reality.
You may not be able to hear that horn 4 or 5 cars back in trains you have been on.
Yet I have been walking along a line in Germany, and making video-recordings, in a wooded valley, without much background noise. I could hear the whistle of an approaching train while it was still minutes away from where I was - the train must have been still at least 1 km away, probably even more. That's a lot further away than 4 or 5 cars back.
And at home, in the past the trains used to whistle regularly in foggy weather. On quiet mornings I could hear the whistles as far as the next station, which is about 5 km away.

Well while that is true, and I am understanding you right, the problem you're pointing out is not a problem. I am addressing sounds specifically in the #5 view, not cab or external. So the long-distance of the horn in the #2, #3, #4, and #8 views will not be affected by the above redution I mentioned for the #5 view.

OpenAL Soft theoretically supports that. Possible sound enhancements to be coded at one time in the future:

• Low-pass filter for external sounds listened in cab/passenger view.
  
• Low-pass/air-absorption filter in external views in fog/snow.
  
• Directionality for horns.
  
• Echo for horns.
  
• Making horns audible from much larger distances.

That sounds like an amazing plan of action to me!

For those also whom don't get the big deal of this, here is an example after editing sounds.
