The microphone in your circuit turns mechanical vibrations (noise, talking, music) into a very small electrical signal, the signal is proportional to the level of sound. This sound is amplified and the amplified signal is used to turn on the LED indicators. In your own words, state the following: when the potentiometer is adjusted to make the circuit more sensitive to sound, what is the circuit REALLY more sensitive to
