Thanks, Bert. I knew there was a name for the concept. What I'm picturing is more comprehensive- I'm thinking of a vast area- a 'perfuming of the air', so to speak. However, as I'm not fond of artificial perfumes, the noise would probably drive me batty! I'm not terribly fond of wind chimes, although I know I'd get used to wooden or reedy ones.

There is a house nor tar from where I live that always makes me feel that I'm hearing wind soughing through strings, and yet when I stand still and listen I don't hear a thing. Should check that out- I already know some of the history of the house.
