With all due respect for the research or the researchers, and if I read the paper correctly, they discovered that inducing vibrations to something sensible to vibrations (at a given "right" frequency of course) causes malfunctioning of the something. And, though technically it can be said (as stated in the conclusions) that the technnique may represent a "non-contact DoS attack", the experiments with speakers placed at 15 and 25 cm from the device cases don't really qualify for "feasability of real-world attack". I mean if you can get access to be able to place a speaker within 15, 25 (or even 500 cm for that matters) from a device, there are much easier ways to attack it. If you could somehow transmit the sound waves/vibrations with enough intensity to be able to affect a hard disk from another room or from the outside of a building, then that would be a feasible realworld atttack.
