Inside the crawl space. The left side would be the side of our house wall.

Little crevice to give access to crawlspace

Here's the floor joists and some of the piping that makes a lot of noise. You can see that there isn't much of anything. Floor joists, pipes and the wooden frame to hang the basement drywalls.

Here's the actual crawl space. It's enough to squeeze through, maybe 2 feet clearance if I'm being generous. Some areas of the crawlspace are completely unaccessible.

So what would you guy's do to reduce upstair traffic noise? Pipe noise? Think I'll need to remove the drywall ceiling panels? Budget is an issue so I'd be doing most of the labor myself.
