There are cheapo dB meters on ebay with a USB capability:
It only mentions Windows drivers, but who knows, someone may have
created Linux software by now. I'm sure they aren't laboratory
quality, but you could probably hack something together with a Pi or a
cheap kijiji netbook to log the data for about $100. Even if they
aren't super accurate, you could gather all your data which is
relative to each other, then reference the cheapo meter vs a good
quality one and figure out a correction curve to apply after the fact.
