Ceiling fan affects sound

From time to time I noticed my system didn't sound right. Some material, particularly steel string acoustic guitar and piano, had a quality that faintly reminded me of a flutter issue with old open reel.

At first I thought it was just me. I've always been aware my listening experience can vary with how tired I am and where my mind is, but this seemed a bit more.

It finally hit me. I'd moved a ceiling fan into the room and with the onset of Spring had started using it here and there on warmer days. After some experimentation, there is a direct correlation between the speed of the fan and the interference I hear. High is the worst but medium is still quite noticeable, depending on material. The effect on low is barely present but still there. Had only low speed been used, I might never have put two and two together; I would have just figured some listening days are better than others.

The room is not terribly big (13X15 with 10' ceilings) and the fan is a 5 bladed 48" one if anyone else has noticed this issue in their listening room and wants to compare notes.
