I agree, that the drinking "shhhluuuhhhrpp" is too much.
But I like the sounds very much. Even when I am not playing, I leave the game on so I can hear the sounds in the background, because I find it relaxing. The hammering of the builders, the children playing, the craw-birds flying, the water-splashes ..

And yesterday one of my villagers was enjoying the beach: he was walking near the place where the dry grass is to be found, and I heard him whisteling a tune!
