Not quite, Ara

I didn't say 10 to 30 Hz I said from 10 Hz to 30 seconds.

What I should have said was 10 Hz to 0.033...Hz or periods of 0.1 to 30 seconds.

The knocking and clicking comes from the shorter period phases which are seen as short bundles of waves. Rubbling would be the longer lasting long period energy.
