hmm, strange. I downloaded a couple of windows-based sound analysers and when the ultrasonic was playing they didn't pick up any spike on the 20hz end, so I ran frequensee and scanned all around my laptop (not sure where the speakers are) and it picked up a small spike but nothing like what my phone was picking up when it was playing through my phone. Back to headphones in phone for the moment. I have cheap $2 headphones but they're stereo at least. Was planning to get a more expensive pair today but forgot.
