The article headline does say it's the SOS pattern. If so, great, but I think they're just conflating regular bangs with the SOS pattern. No other article I've seen says that.

At any rate, I see where you got it.

Oh and while looking I did see this comment on a Reddit site, six or so down:

Not SOS to my knowledge, but also nothing confirmed - origin or pattern. If I’m not mistaken you’re supposed to bang one time every 30 minutes so that I can be picked up on sonar. It wouldn’t make sense to signal SOS since it’d be a waste of valuable oxygen and by the time the sonar reads it, it wouldn’t be picked up as ‘SOS’ — but I’m happy to be proven wrong :) I think if it was even a semblance of SOS they would’ve said something though like “repeated pattern” or “bursts of noise”.”

And I saw this while looking but don’t know where, did not copy the source and can’t find it now.

“Some guy on CNN saying that banging for 3 minutes 30 minutes apart is a well-known distress signal in the military and that’s proof they’re still alive and that’s a good thing. To me that just makes it worse if these people are still alive 4 days into this nightmare”.
