Well, kinda. Just make a repetitive sound and check the power drain in the
PC to see if it induces a repetitive current draw. In other words,
measure correlation over a long term. Other than a microphonic
component, it's not likely this test will find a correlation there.
That assumes that there's no store-and-forward internal element, and that
PC operational 'noise' isn't dominant (over the long term, like hours, noise
will average to zero).
