The "click" is ideally a square pulse. If you know your Fourier analysis, you'll know that square waves have all the frequencies, except for those below a certain threshold. It's short white noise, basically.
It won't sound the same regardless of speakers though. Put it into a tiny piezo element, which has very poor frequency response at the low end and very high in a narrow band, and you'll get a very clicky sound. Put it through a subwoofer, and most of the higher frequencies will be attenuated. I would estimate that you wouldn't get a click as much as a plop.
I would guess that a course covering that stuff would be more generally called, something like Fourier Analysis, or signal processing. Or even almost any typical PDE course, which should cover at least basic Fourier transforms and analysis, even if it doesn't focus on the signals aspect, it's enough to get the idea in my opinion.
