A Fog Machine Silencer


One common problem in using a fogger is noise. The machine’s hissing sound is particularly undesirable in an intimate space, since it distracts the audience and also reminds them that technology is being used to create an effect.

Fortunately, the problem can be easily and quite inexpensively solved. C. Windsor Wheeler, Master Carpenter of the 1985 Champlain Shakespeare Festival in Burlington, VT, borrowed principles from the firearms industry to construct a silencer that solved the problem quite well.

Mr. Wheeler bored a series of uniformly spaced ⅜″ holes along the length of two pieces of schedule 40 PVC pipe, one measuring ¼″ × 18½″, and the other, 3″ × 18″. See Figure 1 for hole placement.
