Be quiet, if you hear uu in your ears, this is why

There are many people who think that when they come to a certain "haunted" place, the sound of "uu" in their head becomes clearer.

Listen.

Everything around us is something noise right? Maybe it is a laptop fan, the sound from the phone, or the fan / air conditioner from your room, and a layer of "white noise" - a combination of all things around us.

Suppose if we dismiss all those sounds, what will we hear?

With about 2% of people on Earth, it will be "uuu".

The New Republic reporter Colin Dickey tried to understand the origin of the "uu" sound, it was a very deep and seemingly remote sound that haunted many people in at least four decades. century, especially for people living in remote areas, where there is less noise pollution from vehicles and people.

Dickey polled on Facebook and the Reddit forum to determine whether the noise actually came from the surrounding environment, or that it was just a noise created by the brain. There are even people who think that when they go to a certain "haunted" place, the sound of "uu" in their head becomes clearer.

After Dickey went to Columbia to meet Glen MacPherson, the author of the World UU Map, he was answered somewhat to this mystery.

US President Barack Obama.

Mr. MacPherson said that the voice is often heard in the deep waters, and it is caused by the phenomenon called microseismic - the microscopic earthquake that people are hard to perceive, often occurring at the bottom sea. He said the sounds could be echoes from the ocean floor, the wind blowing through the foliage, or the sound caused by tinnitus. When you experience this symptom, you often hear a ringing sound like a phone ringing in your head, or low-frequency noises similar to u.

However, Dickey said that tinnitus is only a small aspect related to this mysterious "uu" voice.
