You hear the roar in there? It's a lot of people for the prelims but the sound in the Delta Center in SLC is shit. It has no sound treatment so it is loud AF. They used to put the decibel level on the screen during Jazz playoff games so I think they intentionally make it loud as hell in there by not using any sound treatment.
It definitely adds to it. Watching from home, it sounds awesome. Trying to watch a concert in there, you have to wear earplugs and if you aren't on the floor, it sounds like loud ass with an echo lol.
