I just rang them - "oh yeah, we have tons of that stuff" so I'm off there
tomorrow.

Their website describes some of the weird and wonderful stuff they have -
there has to be a domestic use for a 6' dia x 20' long polished stainless

The fundamental frequency f = c/(2*L), where c = speed of sound in air ~ 300 m/sec, and L = length of the pipe = 6 m. So f ~ 25 Hz which is just barely within human hearing range.

So I guess the next question is, does the Black Hole have
more than one available? Could we do something like

What is the gauge of the walls, anyhow?

The fundamental frequency f =3D c/(2*L), where c =3D speed of sound in =
air
~ 300 m/sec, and L =3D length of the pipe =3D 6 m. So f ~ 25 Hz which is
just barely within human hearing range.

How does that compare to the Taos Hum?
