According to various, but not necessarily all, embodiments there is provided an apparatus comprising means for: controlling one or more electroacoustic transducers of a device to create a 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 by the standing wave; causing analysis of the signal to determine whether there is a defect based on whether the signal represents a sound that would be expected to result from vibration of the component driven by the standing wave in the absence of a defect.
