Australian researchers released an audio recording Wednesday of an underwater sound that they say could possibly be related to the final moments of missing Malaysia Airlines Flight 370.
It's a long shot, but researchers at Curtin University near Perth, Australia, have been studying records from underwater listening devices, including those meant to monitor for signs of underwater nuclear explosions, in an effort to help find the missing plane.
"One signal has been detected on several receivers that could be related to the crash," said Alec Duncan with the university's Centre for Marine Science and Technology (CMST).
Researchers have been analyzing the very low frequency sound for weeks to see if it was "the impact of the aircraft on the water or the implosion of parts of the aircraft as it sank," Duncan said. "But (the source of the noise) is just as likely to be a natural event."
