Sounds like a motor running from a hot tub (had our renter turn off his) Noise still there. It has a steady, low hum and vibration. Sounds like it's swooshing from one end of the house to the other. All coming from the attic. Sometimes the sound is louder, like a motor kicking in to its next cycle. Sound is similar to a refrigerator when it's running. Turned off the power, noise is still there. In addition, sounds like my PC running. Turned off the power, noise is still there. I've checked the surrounding area, I am still coming up with no source to this horrible hum. At this point in my life, I am trying to find the perfect sound/device to mask the hum. I will never stop my search to find out where the noise is coming from.
