Since the landmark series of AES Journal articles on Screen Current Induced Noise (SCIN), Shielding, and the Pin 1 problem, were published in June of 1995 there has been much discussion of the results and their implications for audio systems. This tutorial will demonstrate SCIN and show a Spice model that helps to explain what is happening. These effects are often confused with grounding and shielding schemes so we will also explain which interactions are real and which ones are mythical.
