It's a standard subwoofer speaker/driver put in a ported enclosure, running at 30Hz, creating a particularly "fast punch" sub. The design of this would have all the same goals of a normal subwoofer: moving a bunch of air at low frequency. You can buy this sort of design to listen to music in your car [1]. It all runs on 12 volts because it's standard car audio equipment.
Subwoofers can definitely harm human ears, but definitely not human flesh. Just don't put your ear up to it.
There's plenty of links in Dublin comments for other instances of the tech being developed at least partially, and at least one for in-home fire suppression. Given that last one, I'm thinking it operates on the basis of resonance rather than amplitude to disrupt combustion.

out of curiosity, would something like this hurt a human? I assume the sound waves must be pretty powerful to put out a fire.

Seems like a standing wave thing to halt airflow rather than "overpower with Bill & Ted's Awesomeness!".
Depending on what they have going, it might be loud, might not.
