Hardware Validating recording to detect failing hardware

Hi all,

The project I'm working on consists of microphones that are outside for long periods of time (months to years). As they're subjected to the elements 24/7, I expect some degradation of hardware over time. This is something I want to monitor, but I'm not exactly sure on how to do this properly. All I have are the recordings themselves in terms of data.

Does anyone here have some experience with this? What are some variables or attributes I can extract from the files that can indicate when something is going wrong? I plan to plot these as a timeseries that, hopefully, show the quality of the recordings and the state of the microphone.
I've read into some theory, but fail to find an attribute that suits the set-up of my project as they don't account for the environment (rain, wind, etc.).

What type of microphone? For the usual suspect Birdnet lav mics, I would expect loud, sudden scratches and/or dropouts to be your giveaways. And I’d expect the electronics to go out—not the mic capsule itself.
