Abstract
A system, article, device, apparatus, and method of audio processing comprises receiving, by processor circuitry, audible audio signal data of intermodulation distortion products (IDPs) based on ultrasonic audio signals received by at least one microphone of an audio device. The method also compares the audible audio signal data to ultrasonic audio signal data of the ultrasonic audio signals. Thereafter, the method determines a plurality of susceptibility values each of a different ultrasonic frequency based on the comparing, wherein the plurality of susceptibility values represent an ultrasonic attack susceptibility of the audio device.
