Scientists used detailed 72cm wings of a well-preserved bush cricket, named Archaboilus musicus, to recreate features that would have made a sound when rubbed together.
The cricket lived when dinosaurs roamed the Earth.
Its song, scientists say, was simple, pure and able to travel long distances at night. Their study appears in the US journal the Proceedings of the National Academy of Sciences.
They say the song should be imagined against a backdrop of waterfalls, wind and frogs and bugs singing to attract mates.
