In the universe, there is always something sound going on.
Interestingly, most of the sounds in this universe we do not hear.
In today's episode, we will hear 10 sounds that you have never heard before.
Whales are the largest animals in the world. We know whales can't make a sound,
but it is not true. A whale makes a kind of sound to communicate with another whale.
This sound cannot be heard by the human ear, so we do not hear this sound. However,
scientists have been able to record this sound with the help of low-vibration instruments.
Many times more than one whale makes a different sound when swimming in groups.
Global warming is melting the polar ice caps and glaciers. We think this iceberg is melting
silently, but in reality, it is not. There is a soft sound in the polar region during the
melting of icebergs. In 2000, Professor Douglas Mikael, a teacher at the University of Chicago,
moved to the polar region, where he set up Seismic Sensors to record the sound of ice melting.
By the sound of the sea we understand the sound of the waves crashing on the beach
and the chirping of birds, but have you ever heard the sound of the deep sea? In 2018,
BBC Earth aired a long 10-hour video series where they broadcast the real sound of the deep sea.
Dinosaurs disappeared from the earth's crust millions of years ago, so we don't know how
these giant creatures actually sounded. However, modern scientists have tried to determine the
dinosaur's sound by examining the dinosaur's height, anatomy, and other animal sounds.
According to scientists, the real sounds of dinosaur is not used in Hollywood or in movies
in different countries. In fact, the dinosaur used to call out in low frequency.
Taos is a small town in New Mexico, USA. The locals have been hearing this kind of noise since
the early 1990s. Where this sound comes from or what the source of this sound is still unknown.
Strange as it may sound, this sound is heard by the residents of the area
and the occasional tourists who come to visit here.
According to many, the sound is due to the pulling of power lines along the side of the city,
while many believe that the sound is due to the movement of the underground plates.
Nocturnal bats use eco-location methods to keep the direction straight
or to hunt while flying. Basically, a bat makes a kind of sound with its mouth which hits various
objects and comes back again. Surprisingly, we can't hear the sound that bats make.
Now the sound you heard is actually a mixture of different bird sounds but there is no bat sound
in this sound. If we hear this sound at a very low frequency then we will hear the sound of bats.
When there is an earthquake, we hear the sound of various objects collapsing,
but in reality, we do not hear any sound of an earthquake. In 2011,
a magnitude 6.0 earthquake shook the region of Honshu in Japan. A team of researchers
at Oregon State University recorded the sound of an earthquake using a hydrophone near Alaska.
Have you ever heard the sound of ants? Ants also sound like other animals.
When they gather food, they call on their companions,
and when they are in danger, they call on their companions for help.
When ants are grouped together or when everyone is together,
they call out to each other in their own words.
We know there is no wind in space, so we can't hear any sound in space. But electromagnetic
waves can travel in space. The sound of this wave movement is often caught through the antenna.
The sound was recorded from a spacecraft near Earth.
Cassini recorded the sound as a spacecraft passing by Jupiter in 2005.
We see comets in the sky, but hear no sound. You will be surprised to hear that comets also
have sounds. When a comet flies through space, it makes a sound. Today's scientists have been able
to record sound by playing high-powered recorders and we can hear this sound.
