why do Geiger counters make that strange noise and why is it so different to other sensors that just beep?
In: Technology
Because geiger counters are *old school*.
Geiger counters have a tube of inert gas. When an ionising particle passes through this tube there’s a chance it will ionise an atom. This effect is amplified and turned into a little surge of current. That current can move a pointer on a dial or be fed into a speaker, where it sounds like a click.
Now of course you *could* build something more complex that makes a speaker beep rather than click. But why complicate something that works?
