ARS | The Acoustic Modal Method | Kevin Napolitano | ATA Engineering

Building on earlier discussions around integrated testing and pre-test confidence, a common question naturally emerges: can an acoustic source really be used as an exciter for modal testing? Developed in partnership with ATA Engineering, the Acoustic Modal Method directly addresses that question. In this soundbite, Kevin Napolitano, Technical Director of Testing at ATA Engineering, reframes how acoustic excitation should be understood. He explains that both modal shakers and acoustic sources are fundamentally voice-coil actuators, with the primary difference being how force is transmitted to the structure. Rather than applying force through a mechanical interface, acoustic excitation transfers energy through the air. While this changes how force is inferred, it does not change the underlying physics of exciting structural response. This perspective helps connect familiar modal testing principles with an acoustic-driven approach already used in qualification testing. More perspectives from Kevin to follow as the series continues.
