The sound of the implosion was captured on June 18, 2023 by a moored passive acoustic recorder roughly 900 miles away from the deadly event. The brief clip begins with a few moments of relative silence before a deep, sustained rumbling that nears 400 Hz, according to an accompanying frequency graph.

The Titan submersible was on a deep sea journey to view the sunken Titanic ship on June 18, 2023. Its implosion led to the deaths of five people, including the OceanGate CEO.

The audio clip is of what is believed to be the sound of the submersible imploding during a trip to view the wreck of the "Titanic."
