Using sparkfun sound detector #11

Have been trying to create the decibel meter with an Electret microphone but i'm only able to make the sound detection work when i'm screaming into the microphone. This isn't ideal for measuring the sound in focushub. A number of sources suggest that using the sparkfun sound detector is the way to go due to envelope readings https://electronics.stackexchange.com/questions/269005/how-to-hook-raspberry-pi-with-electret-microphone-to-detect-sound-levels-in-db https://github.com/tolribeiro/recnoise http://toribeiro.com/articles/2016-01/sound-level-meter-using-esp8266-arduino-sound-detector
