@atapene, @tuck

I've tried this already. Change in pressure makes a destinct difference, but not enough in my oppinnion. I went all the way from 5 to 12 bars pressure in the hose, and tried it in the shop. There is only one diference in sound, and thats frequency high or lower, as pitch and tone are the same. I want to make the sound tottaly and completly different, for the same reasons Atapene was talking about.

This will require some fancy adaptation of the buzzer, and I'm pretty sure how to make it, but only for one set, as the other set will be the same as it is. Thats necessary for high-end tournaments like EU or Worlds, where there are 2 playing areas, and a need to make a proffesional tournament. For other games where there are 3 playing areas, 2 of them will have to be with same sounds, but one should be continius sound, the other with interval. And thats still improvement over what we use today in 3 playing area's pool.

But thanks for consern Atapene, I want to hear more of it. This one I knew before, but surely there are some conserns I'm missing. Its the usual thing, when doing something new.
