There's definitively a weak signal there, but not much to write home about. This is a recording of an eberline e-120 geiger counter, which makes the "classic" geiger click sound. Recorded with a røde nt-1 at about 4 cm (1. 6") from the speaker. Click here to check out the full geiger sound pack. . . .
This sound is made by my old continuity meter when the contacts are moved around. The clicking sounds similar to that of a more modern geiger counter or dosimeter. I have heard a few over the internet and some of them produce a beeping noise when the max range of radiation level is reached. Please feel free to used this sound. And remember to rate and comment. Thank you.
I really couldn't figure out how to describe this. There must be an industry standard description for what i'm calling a diminishing reverb. It was the metal funnel in a stove top espresso maker as it was rolling on a tile counter and got got in the tile grooves.
