The point about participating in a conference call is a bit sus. The

Assuming the participant is using headphone. It does help with half the
equation.
That's an interesting point. Maybe it might eventually be possible to use this to do some kind of beamformed noise cancellation.
Shades of "the cone of silence".
HOWEVER - if this would work for people with hearing impairments, it
could be a huge breakthrough.
It doesn't really generate sound in people's heads, that was the journo
being lax. It just generates sound very close to the ear. I suppose if
it can generate very loud localised sound it might be useful to the
hard of hearing, but vibration is vibration, and if it's big it will be
transferred to the surrounding air. Unless (and this is pure
supposition) they actively suppress the generated vibration in the
space round the focal point by e.g. generating equal and opposite sound
(like noise cancelling headphones do).
It's beamforming so they create a bunch of beams of sound that converge at one
or two points. (That's not a technical explanation.)
