A lot of the time our hearing can play overtime. Sometimes we hear things that are not there and sometimes we don’t. Some sounds need more than our ears to be able to hear them. Now, earth is full of mysterious sounds both up in its atmosphere and under its oceans. A balloon released into the earth’s atmosphere at 36km recorded various sounds including the sound of a freight train, crashing waves, and crackling and rustling. Some have described these sounds as sky quakes while others have described them as booming sounds. Some people around the world continue to report hearing a low frequency humming sound around them. The origins, or causes, of these sounds continue to remain unidentified.
One rather poignant sound that can often be heard at sea is only described as the loneliest sound on the planet. The sound of the foghorn of a docked ship is often blown at night and that eerie sound pierces the darkness and sounds very sad and lonely. But most reports of sounds heard at sea and under water are limited to only seafarers and not the general public. One of the most mysterious sounds in the water, and indeed the world, is the “Bloop” which was first recorded in 1997. Researchers say that the sound is caused by ice quakes inside large icebergs scraping against the floor of the ocean.
Even space isn’t a hundred per cent silent, according to space agencies. Since sounds do not travel through a vacuum, astronomers turn wave forms in space to sounds using the process of data sonification. They’re not really hearing the sound but get to imagine what it might sound like using this method. They say that loud explosions emanate from the surface of the sun and a type of eerie moaning or groaning sound comes out of a black hole.
Even though astronomers generally agree that space is relatively silent, some astronauts report hearing a strange sound across the whole of space, almost like the Gregorian chant of a choir. Religious people believe it could be the sound of angels praising God.
But some sounds can be heard only by a few individuals. For example, the humming sound I mentioned earlier has only been heard by a very small percentage of people. Of course, that doesn’t mean they’re imagining it. It might just mean that, for some reason, their ability to hear is ramped up. But we mustn’t forget that hearing sounds no one else can hear could also be attributed to problems with the inner ear or because of stress, both of which can cause an individual to hear strange sounds in their ear. Sounds such as loud musical instruments, crowds of people in a distance chatting or a continuous high-pitched beep or even crashing waves. These are nothing to be alarmed about and, if you’re hearing them, you’re not crazy.
Unlike the notion that when people look at something they sometimes see what they want to see, it’s not the same with hearing. Even though your eyes may be able to play tricks on you your hearing can’t. Sometime ago, someone reported looking out of a plane window and seeing what looked like a dark figure walking through the clouds. Hence, seeing what they want to see. But if you say you hear a beeping or humming sound that no one else can hear, rest assured you are indeed hearing it even though it may not be coming from anything around you.
And there some sounds that instantly relax you. The sound of birds chirping, the sound of the wind rustling through the leaves of a tree or even the sound of a running stream in the woods. People have been known to use such sounds to help them sleep. These sounds often send people to sleep because they are sort of constant and repetitive. In the old days when the television transmission ended, there was a sound at the end when everything stopped. This sound is now known as white noise and is popular with sleep gurus.
