Claim 17:
18. A non-transitory program storage device readable with an apparatus, tangibly embodying a program of instructions for performing at least the following:
determining control parameters of one or more electroacoustic transducers using a finite element analysis of a model of a device;
controlling the one or more electroacoustic transducers of the device to create a standing wave based on the finite element analysis of the model of the device, the standing wave having a displacement antinode at an expected location of a component of the device;
receiving a signal representing sound generated by vibration of the component driven with the standing wave; and
causing analysis of the signal to determine whether there is a defect based on whether the signal represents a sound that is the same as a result from vibration of the component driven with the standing wave in an absence of a defect.
