Real Use Case
You are trapped under debris after a structural collapse during an earthquake. Your voice cannot carry through the rubble. Rescue workers are systematically searching the collapse zone. You blow three blasts on your Fox 40 whistle. The 115dB signal cuts through the debris and concrete. Rescue workers pinpoint your location within 4 minutes and begin extraction.
