To Paul Porcaro, it sounds like the idling engine of a faraway car. His wife, Sadie, hears moving water.
However it is described, "The Sound" can't be found.
For the past two years, the Porcaros have been troubled by a strange and unexplained noise at their home on Anderson's east side.
"We keep the radio on during the day just to drown it out," Paul said. "At night, it's hard to sleep."
