DC got incredibly loud due to the metal bleachers and the kids stomping repeatedly on them. It sounded like an approaching storm.
It was really quite impressive.
I expect FLR to be quite loud with 49 teams wedged into the Gordon Fieldhouse and it's designed for spirit (large floor space for teams to basically come down to and get their spirit thang going).
As for standing next to the speakers I was next to the speakers alll weekend in DC. The sound in that opening video actually vibrates through you and I swear it's displaced something internal.
