It would depend somewhat on the type of mic. While they're supposed to last a long time, you have heard or read about electret mics losing their magnetism. Maybe this was from being near something that demagnetised it? Anyway, something like an SM57 will either work or not for millions of years. So I doubt you're asking about a dynamic mic. Condensers? Not much to go wrong again. Ribbons? I suppose if you had the ribbon sag a lot you would get lower output. Or, if the preamp you were using was low impedance in, and the high impedance ribbon wasn't a great match, and you get a perceived loss in volume. But, it really depends on the mic, and how you are using it. And how you know the output is lower.
