This is like the altered eyeglass frames that make some facial recognition systems misidentify. Carefully constructed 'inaudible' could also mean 'transparent to our perception' for this class of exploit. I could envision an exploit that monitors the ambient noise in a location and mimics A/C startups, vacuum running, blender, whatever could be used to cover almost anything.
