Diesel "loudness"?
Do diesel trucks get louder as they age, or were ones built years ago that much louder than today's diesel? I test drove one recently, a 2016 ram 2500, and it was rather quiet... only a bit louder ...

Ford 6.0's have gotten louder with time, and you can thank Ford for that. After the first few years, Ford dialed back the pilot injection to try to get more life out of the injectors. Side affect is more clatter, but it helped the injectors make it though the warranty.
But generally, each generation of diesel has gotten quieter. I read a Q&A with a Cummins engineer about the new light truck diesels, and he stated they could be even quieter, but the focus group studies found that some buyers don't want a completely gasser-like sound, so they turned diesel sound-track back up a tad. And the "drive-though test" is an actual field test they do when developing new revisions!
