The input is given through the electret microphone. The capacitor C1 filters the dc signal and allows the ac signal to pass through. The filtered signal s allowed to the dual op-amp. The 2 non-inverting amplifiers in the dual op-amp amplifies the signal. The other capacitor C3 further filters the dc signal and allows only ac signal to b amplified. The SW1 and SW2 are the same switch connected internally. The sliding switches are used to set the gain and then with that gain the output voltage is set. The transistor acts as a switch. If the voltage exceeds the given level, the transistor closes the circuit and the LED glows. If the noise in the room doesnt exceed the given level, the circuit remains opened. This circuit just indicates if the noise in the room exceeds the given level.
