Looks like it did for one person.....my question would be if these people hear the hum. Why Don't they also get that tinnitus, and ringing within the inner ear?

Who hears the Hum?
Only about 2 percent of the people living in any given Hum-prone area can hear the sound, and most of them are ages 55 to 70, according to a 2003 study by acoustical consultant Geoff Leventhall of Surrey, England.

the Kokomo Hum was isolated in a 2003 study financed by the Indiana city's municipal government.
