Is there a good way to measure the intensity of relatively quiet sounds at home? Using a Radio Shack digital SPL meter didn't work at all--that is designed to measure at volumes loud enough to potentially damage hearing (lowest level is 60 db or so). I'm trying to get a sense of the volume of general background noise around here, which is sometimes distracting, i.e. my neighbor is playing a stereo (not insanely loud, but the bass comes through the building), there's traffic outside, my computer has a fan whirring, a plane is passing overhead, etc. I'm not sure what to do about this, either to measure the noise or to mitigate it (don't suggest earplugs, I can't stand them). Thanks.
