This discovery is thanks to Perseverance having microphones. It's crazy to think about that 2021 was the first time we had working microphones on Mars.

The first Mars Microphone was originally supposed to land in 1999 on the Polar Lander, but that one didn't survive the landing. The next was in 2008 on Phoenix 's Mars Descent Imager, but in integration testing a bug was discovered that made the Descent Imager risky to use, so that was never activated. And on all the rovers since then a microphone wasn't deemed important enough compared to all the other possible payloads
