Sylvanna Devlin

I am Melissa Devlin, but you can call me Sylvanna.

If your house sounds like an organ going off.

And there’s no built in audio system?

It’s probably a bunch of google plays popped down the air vents by robot crawlers.

That reverberates like nothing else!

The house doesn’t need to be condemned.

But those air circulation pipes need a physical cleansing!

Industrial design will reverberate too. And bridge city?

A little vulnerable to sound.

BTW

Mythbusters tested the artificial earthquake machine Tesla proposed. They made a smaller design.

It worked.
