Unfortunately it's not easy to record. A university technician here has attempted to record the noise during the daytime and failed. He can't even hear the noise himself but others near him can. He has the typical amused response and attitude of those who cannot ever hear the noise. People with defective hearing should *not* be involved with tracking down odd noises. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Hum Sufferers" group.
