Getting esoteric on infrasound Re: [sdiy]

[Tim Ressel]

Yo,

I recall seeing a science show where they were testing
structures for seismic strength. They used a bunch of
plywook horns of varying size, with a pivoting flapper
at the throat, actuated by a motor and cam. These
horns were arranged in a wall firing at the house
being tested.

You can generate a lot of acoustic power out of such a
structure.

Um, are you sure you're not some super-villain about
to destroy the world with low-frequency sound? Because
I would feel real bad if you were.
