Let’s put it this way. Curiosity in our marketing department is driven by instinct, and knowledge about the performance of our sirens doesn’t often extend into the academic realm. Briefly, we wanted to learn more than just the numbers hiding behind the power of our sirens.

The end justifies the means. We decided to do the siren testing our way and put our weakest 300 W version of the Pavian electronic siren to the test for sound pressure strength. How did it work? We hooked up the siren in an anechoic chamber, set the scene for the video shoot and prepared the objects we wanted to observe the sound force on. In our company, electronic sirens are most often tested in industrial ovens in extreme temperatures. Our procedure was, therefore, a whole new ball game, as was the choice of subjects we decided to experiment with. Those that made it into our videos are table tennis balls, wax candles, candy lentils, balloons, and paper ships.

Our expectations varied, and our software and hardware developers’ assumptions about the test results also differed. However, several of us were impressed in the end, and it turned out that the power of sound can be seen with the naked eye. I won’t reveal the course and effect of the individual tests because if your curiosity is at least a little similar to ours, you can click on the individual videos yourself using the links below.
