This is our first sound reblog from Noise Jockey, who tells us about this Mexican Ceiling Fan:
When in Mexico two years ago, the villa in which I stayed had a ceiling fan with very different voices when set to low and high. I’ve included a short sample of this fan at low, sounding like a grinding motor, and high, when the motor when silent but the blades sounded like a small helicopter.
