Any way to use your rig as a Decibel Meter?

In other words, do I need to drop the cash for a meter or do I already own the shit to have one through my rig?

What would be a semi-accurate way to measure this? I know this is kinda depending on different mics as they have a certain sensitivity or whatever, but is it worth trying if it is possible anyways?
