What is the meaning of strange noise?
Why am I hearing weird noises in my house?
The many materials that make up your house — wood framing, plywood, glass, metal ducts, nails, plumbing pipes — all expand and contract at different rates. When a house cools at night, these materials may move slightly, rubbing against each other and making noises. Occasionally, they'll contract with an audible pop.
What does the mysterious hum sound like?
They say it's only heard indoors, even in some rooms better than others, and it's low-pitched, like a distant truck idling. Some also feel a vibration, like Dale, but most just hear a hum. However, they all hear it at different times of day, and at varying intensities.Nov 1, 2021
