In Part 1 of this Design Idea (DI), we saw how a standard electret microphone capsule can be persuaded to detect infrasonic signals down to a fraction of a Hertz by adding some fairly simple ...
Part 1 of this DI uses an electret mic to detect infrasound. It starts with a basic equalization circuit validated with a DIY test fixture and simulations, and ends with a deeper analysis of the ...
