Audio Detection and Sound Classification – Benchmark
https://benchmarkmagazine.com/audio-detection-and-sound-classification-2/
If basic audio detection only uses volume levels as the basis for judging exceptions, then a wide range of other sounds – laughter, calling after a customer who may have left an item at the counter, staff issuing general instructions to a crowd, a passing vehicle backfiring – could also trigger an alert or action.

AN1991 Audio decibel level detector with meter driver
https://www.nxp.com/docs/en/application-note/AN1991.pdf
Audio decibel level detector with meter driver Figure 2 shows that the circuit is within 1.5 dB tolerance over the 80 dB range for audio frequencies from 100 Hz to 10 kHz. Higher audio levels can be measured by placing an attenuator ahead of the input capacitor. The input impedance is high (about 50 k ), so
visual-basic-6 - audio level detection | DaniWeb
https://www.daniweb.com/programming/software-development/threads/27640/audio-level-detection
It's a VU meter using the principle I worked on for level detection, i.e. it puts the sound card in record, grabs samples, and measures them. Its all VB6 with no 3rd party controls. This works even using DirectX components for play, but will only work if your sound card's full duplex (most are now aren't they?)

Simple Sound Detection Circuit. Detecting Sound
https://picaxe.com/docs/picaxe_sound.pdf
Sound is made up of constantly rising and falling waveforms (try looking at the output from a microphone on an oscilloscope). Therefore to detect the highest sound level you need a reference point, and this circuit therefore only looks at the ‘negative going’ part of the waveform. By amplifying the point at which the sound waveform
