"The Hum" Scientists think they have found the Answer

[Nanny]

I hope they're right. I do like their confidence-level. It says the sound lasts from "13 to 300 seconds." They HAVE to mean each pulse or wave of it does because that sound can last for a half hour, even. Also, it's described as sounding different in different regions and various sources have said 3 or 4 different sounds.

I've had to tolerate it sounding precisely like a jet engine and other times like a train way in the distance, but problem is that I do not live even within a hundred miles of a train track. Being sensitive to this/these sounds is something that a person best be a very confident person because what others may think of it shouldn't be something to care about. But I bet some poor folks do.

Remember THE HUM?  That pesky noise which many have heard, often at night?  Well scientists think they have found the answer to this strange HUM noise.
