Re: free field

[Bob Masta <masta@xxxxxxxxx>]

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!
