It's made watching Sumo a very different experience. You can hear every breath. You can hear the swish of the bow in the ending ceremony. It has been quite interesting until Takayasu's injury today - hearing his howls of agony in a silent auditorium was heart wrenching.
It’s the best part of sitting close to the court. So much shit talking and bravado.
You can normally hear Carmelo Anthony calling for rebounds over the crowd, music, commentators, and probably your own internal monologue, so people have had some practice.
