--------------------------------------------------------------------------------------- "Now that you mentioned it, I do vaguely remember that fans can cause interference patterns in the sound, etc., but I certainly did not think of itat the time. This effect was a first for me!"-------------------------------------------------------------------------------- As an experiment take a recorder and play a steady long note under the ceiling fan with it off. Have someone turn it on while you sustain the note and listen to the wave pulse accelerate. Quite dramatic, the steady pure recorder tone is prefect for this. I've shown up with a recorder at client I know has a ceiling fan but didn't believe me when I asked for it to be turned off the previous year. Ever try singing into a table fan.
