Does the ceiling fan affect the sound?

Tbg Nonsense should be berated, not tolerated especially when spread intentionally or merely for ones amusement or profit at the expense of others by those who should know better.    

The electric fan is run by a motor. So is the refrigerator. Try this experiment ... unplug all appliances ... refrigerator, fan, TV and computers. Then sit down for a new listening experience. 

Be sure to tie a big string around your finger so you remember to plug the refrigerator back on before you go to bed. 

And for the fuse deniers ... put a couple of fuses up your noses for a new experience. The sinuses become extra clear with a lot more depth.  

Happy listening ... 

A strong breeze does degrade sound, as when at an outdoor concert or event.  In a strong crosswind, the sound waxes and wanes as the air it traveling through is suddenly replaced by different air blowing in.  The air in your room is fairly stationary--not sure how much of a breeze it would take to distort the sound.  Another puzzler--does your system sound better through clean air---do large dust particles and dander distort the sound as it is propagated through air molecules? Whoa, an audiophile air purifier!  Ultra filtrate for clean sound..........  

All joking aside, bowls of cold water on the floor out in front of the speakers are the only way to fly if it's modifying the way acoustic waves propagate through air you're after.

no kiddin' either:
was recently in Pour House where bunch of fans turned on and AC too Neither fans or AC stopped me from enjoying live music. No distortion heard due to the multiple ceiling fans and AC.
Noted that musicians often placed bottles of spring water on top of  PA speakers or instrument amps. Isn't that sounding "tweaky"?
