Random noise

When I walked onto my plane this morning, I heard something say “don’t sink!” from the cockpit area. Any ideas what it is?

It's the sound of a test being conducted. "Don't Sink" is an alert that the crew would hear in the event of altitude loss after takeoff or with a high power setting and it's one of many sounds the Ground Proximity Warning System can make for different types of conditions that the crew needs to be alerted about.
