I had much the same experience on the one night I saw the Hornets play in OKC.
Over time, I've grown to appreciate or at least accept the sounds during the game. It engages a wider range of people and creates new fans. The Thunder sold out last night for the 120th something time in a row. That's 18,000 people in OKC for basketball. The place, as usual, was packed. Make no mistake, the real draw is the great, great level of play. But, the sound plays a part in the overall entertainment and adrenaline rush. It brings in people that aren't particularly basketball fans and makes fans out of them.
Is there a rule against sounds during play in college? Seriously, is there? It started in the NBA, not as an idea from the league. It started with one team doing it. They allowed it to continue and now all the teams to it.
So, I say to OU. Be the first. Be like Oregon with the fancy uniforms. Be a Baylor and build a competitive power out of notoriety. The purists will complain. That's good. It will keep the traditional powers from doing it early on. Maybe the purists will go away. That's good. The purists aren't filling the arena anyway.
And, Bigtime. My purpose here is not to display my unhappiness with OU, although I'll admit, I'm not a fan of the athletic administration or their old fuddy duddy ways. I remain a fan and I want to see basketball thrive again at OU like it used to. I sat in that arena the last 3 or 4 years with maybe 3,000 to 4,000 people in attendance for all but a few high profile games. On TV last year, the stands still look relatively empty. Look, I'll go away. I haven't posted here in several years. I don't intend to be an antagonist. Attending the scrimmage drew back in. It might as well have been a basketball camp. It was open to the public, but I guess they have long since decided no one would come. They made no attempt to really promote it. OU trotted out an autographed basketball as part of the "entertainment". About 10 people signed up.
Be the first, OU. Embrace change. Embrace the event as entertainment, pack the place, bring in recruits because of the notoriety, be the first, be the best again.
