The rules say you are not allowed to talk while the ball is heading towards your opponent , if you do and they hear it they are within their rights to call a hinderance. It doesn't matter how loud you said what ever it was. The fact that you said it and they heard it means they were distracted to some degree.
I don't dispute what you say or what the rule is.
What I can say that I have played a bucket-load of USTA matches, and a lot of people talk/yell when they are supposed to be quiet. Yet I've never called a hindrance before and have never been called for one.
What that says to me is that players are not in fact as easily distractable as you suggest.
I guess what I am saying is that a player who claims a point due to hindrance if their opponent says something legitimate should be quite clear in their own mind that they were in fact hindered. I sensed in some of the posts that folks were calling hindrance due merely to the fact that the opponents talked and not necessarily because they were hindered by the talking.
