The first will be very hard to make as a DIY project, the second can be done with a microphone on your computer and suitable software.
there are auditory dosimeters available, but building one from scratch will require a bit of knowledge in both electronics and both digital and analog frequency detection; or as you wrote, use the equipment already available with a bit of software and he'd be set. There are probably much better one's available then something like this.....
Oh, thanks for that new knowledge!
When I work in a nuclear facility, the dosimeters are in fact VERY simple, they are effectively a gold-leaf electroscope. We are given a "pen" like device, with a window in the base, which allows a microscope to read the position of the leaf. They are charged up and ionising radiation will cause the leaf to move back towards the holder.
Calibration would be tricky, I grant you....
Oh... I thought they were all those badges with film under varying thicknesses of plastic...
The electrometers have the advantage of being very quick to read. I was surprised when I first went, because I expected the film badge type.

Build an electroscope!
It literally can be built from junk, and it hardly requires any complicated hand tools.
It makes for a simple dosimeter.

Do you mean "dosimeter",or do you mean a "meter to measure decibels"?
