STS-116 returned to Earth on December 22, 2006. During reentry the shuttle Discovery passed almost directly over Houston, Texas. Closest approach to Houston occurred at about 4:17 PM CST with landing in Florida occuring slightly more than 15 minutes later. Below is the path of Discovery across the Southern U.S. The image is cropped from one on the NASA spaceflight web site.
Below is a sound file of the sonic boom as recorded by a friend with his MP3 player. The result has been converted to a wav file with a sample rate of 32KHz. The whine in the background is due a ventilation fan in a steam tunnel about 100' away. Some of the increased background noise at the end of the recording is due to people at an adjacent building showing their satisfaction with the sonic boom.

A view of the waveform is shown in the graph below. The sonic boom is the conspicuous event in the middle of the plot. The peaks were clipped somewhat during the recording.
