As loud as you set the amp. It's the frequency of clicking that matters. As an aside, did you know that an ordinary cell phone camera can be used as a poor man's Geiger? Alpha and Beta particles, and to a lesser extent, Gamma, cause discharge events in the CCD/CMOS that gets picked up as a 1px white flash. If you obscure everything and count the flashes against the perfect black background, you can get the incident dose.
