I saw that too, but I think they sort of side-step the issue of music. The bit about noise typically being below 10kHz doesn't really apply to most music. If you go run pretty much any modern record through a spectrum analyser, you'll see tons of content above 10kHz.
Anyway, I'm certainly not claiming to know with any certainty that loud music would work as a preventative measure against this kind of attack. I just don't think the paper sufficiently proves that it wouldn't be.
This is complicated by the human ear's variation in loudness perception over the frequency spectrum, and the effect this has on music. The stuff over 10k is typically mixed quieter than the stuff under 10k, though it doesn't sound that way. Records with lots of energy above 12-13khz tend to sound pretty awful.

EDIT: also pitch is logarithmic with respect to frequency. 8khz sounds really high pitched.
But laptop speakers are notoriously shitty. I don't think laptop speaker output has tons of content above 10kHz.
