I was at the 87 ALCS. It was certainly deafeningly loud behind the sea of Homer Hankies. It's possible, but what would be the point? Baseball uses visual signs, not audible like in football. You're not going to break Jack Morris's concentration with fake noise. I see this more as an example of Michaels' profound hatred of the Metrodome, shared by most of the national media. Can't say I blame him for that. But that crowd, shouting and waving the hankies? As genuine as it gets.
