The amplifier noise level referred to the input is 10- to 12- V RMS depending on the weighting switch setting. This means the meter’s useful range is about 30 to 136 dB SPL. To put this range into perspective, a quiet office has an ambient noise level of about 40 dB SPL and a jet engine at 100’ has an approximate 140-dB SPL.

That’s what this project is about, a simple volume meter (or decibel meter) made with Arduino, a microphone and few LEDs. The Arduino program for this project is very optimized and shortened so you can see what a properly written program looks like. Let’s start with a list of components we need for the project: 1 x Arduino microphone.
