I don't need no stinking whistle!

Well the clock operator should see the hand go up and stop the clock from that in the absence of a whistle when one is expected. The local high school gym seats about 2500 people on four sides, not huge but hardly considered crackerbox. When its full and there is an exciting finish, you don't hear a thing. The only thing to go by is the hand, Fox40 or not. In fact starter's pistols are common during the postseason.
