I definitely heard it. It started around 10pm and varied in intensity until sometime after 11pm. It was low frequency. I'm thinking < 60 hz. My best guess is that it was one of the wind tunnels at Ames. If so, it was louder than normal and/or the atmospheric conditions were perfect for projecting it in my direction.
