Correct me if I'm wrong, but won't this inevitably lead to articles with the title "Researchers detect subsonic boom but can't identify the source"? What other possible benefits could this have? Surely we know about the earthquakes this article says the "tunnel" it will detect.

Article: "But to their surprise, the scientists also picked up other sounds in the channel. “There’s infrasound events of unknown nature that occur several times per hour,” says Daniel Bowman, a geophysicist at Sandia and collaborator on the project. “And there’s no good explanation.”

This could help sort out those worldwide "hum" problems ('Taos Hum','Windsor Hum'. [https://en.wikipedia.org/wiki/The_Hum]

FWIW the now-silent Windsor Hum seems to have been a (particularly ill-maintained) steel plant on Zug Island, across the Detroit River.

They're seeking similar benefit to the tunnel in the ocean. Sure, they can't figure out what it is now but over time they can improve it. Could be very useful to detecting volcanoes for instance.
