Jul 11, 2019 at 21:56 comment added rdtsc Any spark generator creates tons of RF harmonics, even Tesla coils. I'm thinking Tesla coils fall into the "It runs for a few minutes, looks cool, then it sits in the garage for 15 years before being thrown out" category, so isn't much of a concern. I'd say definitely use a Faraday cage. That shouldn't affect the sound noticeably.
Jul 11, 2019 at 21:34 comment added Logan R. Kearsley There doesn't seem to be any problem with musical Tesla coils; I presume that is because they use high frequency AC sparks, and get the tone by turning the spark on and off, rather than resonating at audio frequencies directly. But in case the device does produce notable radio interference, I had intended to shield the row of spark generators with a wire-mesh Faraday cage.
