This was the first paper I published in JASA, where we looked global active noise control of small axial fan. We figured out where to place microphones to cause large sound power reductions. doi.org/10.1121/1.16...

Even led to a patent: patents.google.com/patent/US200...

We got a paper published today that answers a not-quite-age-old question:

Why does the Falcon-9 booster make a triple sonic boom during flyback?

Give it a read!

Hello, world. Thought I'd give this a shot. I'll mostly share research updates & publications here. For starters, here's a list of my publications: physics.byu.edu/faculty/gee/...

If you're interested in but can't download one, let me know.

And here's a rocket launch pic. (DIVH, NROL-70).
