Intermodulation distortion in the speakers?

The audible effects of the ultrasonic signals may be intermodulation distortion in the speakers producing effects within the audible range.

See Ahihara Kaoru and Kiryu Shogo, "Detection threshold for tones above 22 kHz," Audio Engineering Society Convention Paper 5401, presented at the 110th Convention 2001 May 12-15, Amsterdam, The Netherlands.
