Tthe concept is much older than that, as a listening aid at least. Wikipedi=
a says 1624:

But of course it's even older. We all know how to hear better by cupping ou=
r hands to our ears.

I don't know the work of Mike Rooke, but the idea certainly dates back to t=
he early 20th century. Early European recordists & indeed experimental arti=
sts made all kinds of sonic sculpture using these methods & adapted microph=
one techniques for capturing various sounds. Some of the early weather reco=
rdings (storms etc) were made with a kind of closed ended, cone shaped atta=
chment for example.
