I don't have the equipment to make sonograms myself so I ran these past a friend who does.

This one is just not clear enough to be sure. You should be seeing a strong vertical line running from 20kh - almost 100kh; yours stops at around 70kh and goes down to 5kh. Also there are no definite lines - looks more like static.

The bat was probably just too far away to get a good reading.
