LED Sound Level Indicator Circuit - Making Easy Circuits
https://makingcircuits.com/blog/led-sound-level-indicator-circuit/
Calibration of this LED sound level meter is simple – choose a sounder with a specified output dB level (say 100 dB) at a distance of one inch and put the MIC1 about the same distance from the sounder. After that, configure the range-switch S1 until the 5 th LED becomes lit. This means the sound range is at 100 dB.

The LEDs are for the logarithmic indication (-10/-5/0/3/6dB) of the input signal level. Note, the recommended LED resistor (R1) value at 60°C (Ta (max)) is 47Ω when Vcc is in 8 to 12V range. The KA2284 module can be used in DC mode as a battery level indicator or it can be employed in AC mode as a VU meter for audio signal strength indication.
