Dear List: Bill Hartmann has pointed out a terminology error in my prior post, wherein I mentioned the problem of standing waves in a "free field", which is technically anechoic by definition and would thus have no standing waves. Of course, I meant open field in a typical room with reflective boundaries. Thanks, Bill, for keeping me on my toes! On 6 Nov 02, at 10:21, W. M.
