Sound level meter circuit using IC LM3914 - Gadgetronicx
https://www.gadgetronicx.com/sound-level-meter-ic-lm3914/
Working of Sound level meter: This circuit uses a electret microphone which is powered using a pull up resistor R3 . When there is a sound in the environment Electret microphone picks it up and this signal will go to pin SIG IN pin through Capacitor C2. This Capacitor C2 removes DC components in the signal. Now the IC LM3914 takes over.
