pmm711: You can thank the top players in the game for this...if they don't like something the game will change for them.
There used to be a slider for Ambient Sounds in the Flash version. If you didn't like hearing them, it was easy enough to move the slider all the way to the left to turn them off. Maybe WGT could bring that back and add it to the Settings.
I have never heard of any top players complaining about the ambient sounds.
