Any thoughts about this?

I'd say that the sound absorption idea doesn't make much sense a priori.
I am not an expert on the sort of QM calculations one would need to do
to evaluate the idea, but I haven't seen anything in the literature
about this, and I suspect (based on the context of your message) that
you have done no new theoretical calculations or experiments to lead
you to this novel conclusion.

generally agree with all that.

Wouldn't the "theory" -- such as it is -- be equally applicable to
graphite, say a powder or foam?

An experiment would help? Easy enough with graphite. Maybe even with
CNT if you insist; after all, it would be a non-destructive test.
