Justin, I have done the same thing several times and I have sometimes found it helpful! I'm glad someone shares my level of insanity ;) One time where it was helpful was in analyzing the failure of a connector. We had a test where we were automatically plugging and un-plugging a connector twice per minute. We recorded voltage drop and temperature of the connection with a fixed current flow which was itself switched on and off by a secondary set of contacts which mated after the main connection. The test ran for about 2 weeks, generating about 40 thousand datapoints. When either voltage drop or temperature rise were played as an audio file, the overall quality of the sound was like white noise BUT the amplitude told the story of the connector wear.
