I have a question !Are there rules in relation to shouting, grunting etc on court. Some scenarios:1. Player(s) win a rally and shout out in joy. This happens rarely and only after tough rally.2. Player(s) win a rally and shout out in joy. This happens frequently, perhaps after every 2/3 points.3. Player(s) lose a rally and shouts out in frustration at themselves. Happens every 4/5 points lost.4. Player makes noise or grunts, like in ladies tennis, while hitting their shot or immediately on hitting it. This happens frequently even on fore-court net kills, every 3/4 points.It may happen that these occur in a 1-court hall but what happens if occur in a 4-court hall with other games in progress.
