Strange noise in the sky August 2011 St. Pete,Fl.

On August 24,2011 in St. Pete, Fl.,my husband tried to capture the sound of the strange rumbling that we had been hearing in the sky for 3 days in a row. This is the same sound that people all over the world are reporting hearing. This is best heard with headphones or turn the volume all the way up. If you search for the video“strange Trumpet sounds heard before the earthquake“..(at the baseball game at Tropicana Field) we live 5 mins. from there-this is the exact same sound-3 nights later. Note: The rumble was heard 1 more time on Thursday, August 25th 2011 and an hour after that, I heard what can only be described as a loud,vibrating hum which lasted for around 2 minutes.***UPDATE: We began hearing the sound again on October 22. Exactly 2 months to the day of the first time. PLEASE NOTE; The high pitched noises are cicadas. This is NOT the sound that we were trying to capture. What you are listening for, is the low frequency roar in the sky. Again, this is best heard with volume all the way
