Electronic Duty Cycle Acoustic Modulation — Inductor & MLCC Coil Whine

SMPS power supplies and VRMs convert PWM duty cycle variations into loud acoustic squeal via inductor magnetostriction and MLCC piezoelectric strain. Workload side-channel audio emanation in 3D.

Paranoia, fear & mental health — how to get help

If any of this frightens you: this site documents what signal physics makes possible in a laboratory, which is not evidence about what is happening to any individual. If you feel watched, targeted or unsafe, that distress is real and treatable.
