Cringe-worthy, tacky, unpleasant, pointless...Take your pick. If anything it detracts from any atmosphere and seems to be purely for the benefit of the profoundly deaf. (Yes, I know they should be considered along with everyone else). While getting rid of that, perhaps get rid of the hysterical announcers around the country. It reminds me of the adage that, 'it is sometimes better to let people assume you are an idiot rather than open your mouth and confirm the fact'.
