Sound is pressure — the louder the sound, the greater the pressure. The greater the pressure, the more damage it can do to your ears. If you’re in a noisy environment, it’s important to know how ...
This sound frequency meter circuit is simple to build and can be constructed in a portable format. In can measure frequencies with a minimum level of 10 mVrms and a maximum frequency of up to 100kHz.
This frequency meter project squeezes a lot of performance out of the ATtiny2313 microcontroller. That chip does all of the work, measuring the frequency on the input pin as well as multiplexing the ...
