What sound do falling meteors make?

Usually meteors are too far away to make any audible sound. However, the meteor will briefly create an ionization trail that can reflect a distant radio signal.

If the geometry is correct, you can hear for a moment these signals on the radio ..

In the video shown, meteor sounds were captured by a sensitive radio bouncing off large meteor tracks, while bright streaks were captured by an all-sky video camera.

The video first shows the bright paths traversed by four fireballs across the sky near Lamy, New Mexico, USA. Then, after each still frame, live video captures each meteor flying across the sky, now combined with sound recorded from its radio reflections.
