Just yesterday was watching Territory season 1 where the characters have an intense suspenseful, almost whispering "serious voice" conversation while standing next to a running helicopter, without even raising their voices which took me out of the scene.

So the question is, do viewers want it, or do know it all producers say people do and put it in?

When they say viewers want it, they mean just about 90% won't notice. Most people haven't been close enough to a running helicopter to understand.

I'm having problems watching movies at all, there is so many things breaking my immersion. :-)

Even more than that, they will notice if you don't it the "wrong" way that they've come to expect. This is called The Coconut Effect: https://tvtropes.org/pmwiki/pmwiki.php/Main/TheCoconutEffect

Ah, had no idea it had a name!

My clearest memory of that was me as a kid watching a Bond-movie where a sportscar makes a screaching sound when driving down a sandy beach. I turned of the TV and don't think I ever saw a full Bond movie after that.

The list on the page you linked had one thing that isn't toally correct though:

>The very specific (but entirely unrealistic) echoing thud that is heard when all the lights are turned on in a large spacenote .

That sound is realistic if it is an old building with the heavy type of power relays or whatever they are called. They do make that sort of sound if the acoustics are right. They could be set up with timers so they don't start the lights at exactly the same moment to prevent overloading the fuses.

Have you never walked through sand and heard it screech or squeak? It's definitely a thing.

Surprisingly, it’s also present in live sports, see for example this article (in Finnish) about sounds in winter sports broadcasts: https://yle.fi/aihe/a/20-10005843
