Well I downloaded the Real Traps Test Tone CD which has tones in 1Hz increments from 10 to 300 Hz. That's right, each tone is 1Hz different from the previous tone, and the next. There are 29 tracks with 10 tones on each track, i.e., Track 1 has tones from 10 to 19 Hz with each tone lasting 10 seconds. Just enough time to read the meter and write down the reading. It turned out to be a great way to discover things in my apartment that rattle. I still haven't tracked them all down yet, BUT I WILL!
