Sound sensor

We are plagued by semi trucks running their Jake brakes in front of our house

Can anyone recommend a sound sensing device that would trigger a relay to illuminate a

“Please no Jake” sign

Thank you

This example from the electret mic breakout is fairly similar, you’d just need to couple the output to a display instead…the harder part will probably be adjusting the mic location to a usable place where it won’t pick up too many false positive or ignore true ones
