For the owner who’s invested thousands of dollars for a high-end audio system upgrade, electromagnetic interference or EMI, is a frustrating and common problem. While it’s natural to point the finger at the shop who just performed an otherwise high-quality avionics installation, there’s a good chance the source of the noise has been there all along­—and now amplified by the clarity of a new audio system and ANR headsets.

In this article, we’ll look at the common sources of electromagnetic interference and popular noise suppression products that could eliminate most of it.
