simple average to smooth things out
Will that suppress annoying noises?

A friend from America described his quiet nights in a gated community apart from the occasional gunshots at a nearby intersection. :o Sudden noises include the type that wake you up but you cannot remember what woke you up. Good monitoring should include those peaks.

After you record the actual, you could have programs testing various measurements and averages. Split the sound into frequency ranges. Fourier analysis and similar things can help identify the frequencies most annoying. If the aim is to better sound proof your home, you can look at techniques for each frequency range.

Many common microphones do not pick up common sounds at the same level as human ears. Low frequency doof doof noises are often ignored. Beep beep, reversing noises might be picked up at full power by one microphone or just as a muffled background. Perhaps a good microphone might be supplied with a sound profile for adjusting the frequency response closer to what our ears hear.
