TL;DR
Make the sound of machinery, especially trains, assemblers and belts more "badass"/beffy
What ?
So I heard that now in 17.X sounds will be revised, and in my opinion, Factorio sounds are way too "clean". The train especially, sounds way too friendly. This is what I mean, look:https://youtu.be/GKPDhTCffNw?t=81
See how many different sounds it makes, the tracks, the metalic sounds from the wheels, it's borderline scary stuff lol, and above all its loud. In general, I feel like almost all sound effects in this game are sort of too clean and friendly to some extent. The conveyor belts for instance, could have a more metalic sound like tank tracks, since in game they are all made of metal and gears, a bit like this:

You know, you can kinda hear the gears connecting with the tracks.
Also the assemblers would, in my opinion, benefit from having a more agressive industrial press sound mixed with the sounds it already makes. For example:

Point being, I think the game looks very gritty, but the sounds are way too friendly. Factories are loud, and things sounds like they could kill you if you don't pay attention. The train especially, its annoyingly quiet and sounds like a toy instead of a big dirty and industrial freight train.
Why ?
I think that atmosphere is the main reason, and also to make things sound more impressive/dangerous, as factories IRL are. Sound wise, the most important factor that creates a solid atmosphere at the moment in factorio are the musics, the sounds of the machinery themselves are rather negligible in my opinion, they are not fun to hear or have a presence. The train especially, it is such a remarkable moment when you unlock and build it, but the sound doesn't convey how badass this stage of the game you are in now is, it's a really weak sound.I'm not suggesting that exactly these sounds that I posted gets implemented into the game, it's just a example of the nature of the sounds I think would be very fitting and add a lot to the immersion of factorio.
I created this thread in Reddit too, but there things get burried fast. There are a few other opinions on the subject by other players, worth check them out imo.

Thanks devs for the truly awesome job! This is one of the best games I have ever played!
