HOW MUCH NOISE DO FOG MACHINES MAKE?
Fog machines do make some noise while they are generating fog. Actually, there are two sounds. The sound of the pump as it moves fog fluid from the reservoir to the heat exchanger, and the sound of the fog coming out of the nozzle. Like everything else, the more expensive ones are generally quieter, and the less expensive ones louder. That’s not to say that inexpensive ones sound like a freight-train, but you can hear them. If you want your fog machine to be quieter you can build a wooden shroud to help absorb the sound (we’ll be publishing a how-to article fall 2002). If you are going to use a fog machine in a situation that requires extremely quite operation, such as in a theater, you may need to go with a professional model or use a true dry ice fogger.
