My counterpoints to several comments as someone who attended every home men's game(except 1 when I was at a bowl game), many women's games, most wresting meets, and other functions from fall of 99 through spring of 2004 when I was in college.
1. Carver doesn't get loud. Wrong. At the floor level it can get deafening where you can't hear what the person next to you as saying. As others have said, it doesn't sustain that way through a whole game, but try finding an arena that isn't owned by a blue blood that does. And maybe it isn't so loud at the top, but that doesn't matter for home court advantage.
2. Students don't show up. Maybe they don't right now, but back in the 2001-2002 season we had the largest student section in the country. And up until that team crashed and burned halfway through the season they definitely attended.
3. The arena is hard to get to. Yes and no. Depends upon when the game is. Early weeknight games hurt because you're hitting the post-work commuters. Late weeknight games are easier. Weekend games are fairly easy. Except Cambus doesn't run until noon on weekends, so if it is an early game, students would have to walk which is a pain. Don't know why Cambus doesn't set up special routes on weekends for BBall games.
4. CHA lacks air conditioning which is dumb. Why do you need air conditioning? CHA isn't that hot in the summer as long as the seats aren't full with people. It would only be used in the summer when students aren't on campus and no sporting events are going on. What artist would have a concert at CHA when the students aren't on campus? The air isn't needed for the summer camps that are held at CHA. And Spring graduation occurs in May before it gets really hot out.
My suggestions...
1. Install louvers underneath the tent in the roof over the middle of the court. These can be opened as needed for concerts, etc to help with cooling and sound quality. And closed during games to help trap additional noise in. This would help with the containment of sound to hopefully help sustain the volume.
2. Install suites around the sides of the arena, these suites may need to occupy some amount of the top row of seats so that they don't consume all of the concourse space. Hopefully puts the big donors up high in the nicer/posh suites. These are the people that have problems with all of the stairs or wait for the elevator. It would help trap more noise in to help sustain the volume. And, it would also prevent people from leaving their seats early and watching the finish from the yellow railing at the top. That hurts home court advantage at the most important time all because people know they can watch the end of the game from up there and then get out quick to try to beat traffic.
3. Move the students to the collapsible seats below the yellow railing near the court. Maybe we limit it to certain sections until the need is there to use all of them, but get them down low in the spots that were previously occupied by the people that are hopefully now using the suites.
Those suggestions would only cost, at most, a few million dollars to implement. CHA is a great place to watch a game or meet. Aside from being behind the basket, a problem that every arena has, there isn't a bad seat in the house. We shouldn't throw that away, but should instead do what we can to improve our environment because most of us aren't there merely to watch a game while sitting in the seats.
