10 Strange and Surreal Sounds Captured by Scientists

10 glacier melts

As global temperatures rise, scientists need to know how quickly glaciers will melt, which can help with tasks such as predicting sea level rise. Traditionally, photography and satellite imagery have been used for this purpose, but these days scientists are using hydrophones, underwater microphones, to listen to glaciers. You can ask if Apparently melting glaciers sound like firecrackers and fried bacon! The popping sound is made when bubbles jump into the water. The goal is to count the ratio of bursting bubbles to the number of bubbles in the glacier to know how fast the glacier is melting. This research is much more important than it sounds on the surface. Rising sea levels could have devastating effects on hundreds of millions of people around the world.

9- Unmute animals

We all know the sounds of birds, cats and frogs. You may also know what the fox says. But many other animal calls remain a mystery, especially when it comes to amphibians and sea creatures. Gabriel Jorgewich Cohen, a Ph.D. student in Zurich, investigated whether many such species make sounds, and found that many of them do. You can hear them in his recordings too. Sounds were recorded with hydrophones as well as glacier sounds. Cohen visited multiple institutions in five countries and documented many animal species previously thought to be mute. Among them were 50 species of turtles, lungfish, and other air-breathing fish. He found that none of them were mute. Every animal he picked up made noise. Furthermore, the results suggest that a common ancestor was shared among vocal species approximately 407 million years ago.

8- Whole Earth

In 2014, a sensor was switched on in Indiana, USA, which required him to record every sound of the earth for a year. Yes, all sounds: birds chirping, ultrasonically whistling bats, ocean waves, earthquakes, and everything else. The research was led by his Bryan Pijanowski, who defines himself as a "soundscape ecologist." Unlike ordinary ecologists, Pijanowski does not listen to the sounds of a single species to learn more about them, but to study how those sounds interact with those of other species and the environment. That's it. In his work, he listens to the rhythms and patterns of nature, such as dawn and the world growing larger at certain times. Tracking such patterns can provide scientists with important data about the state of the Earth.

7-single bacteria

A surprising fact you may not know is that all living cells make sounds through tiny vibrations known as "nanomotion". He discovered that he could amplify sounds and hear the sounds made by bacteria. In this way, it was even possible to distinguish between live and dead bacteria. Interestingly, the graphene turned out to be so sensitive that we could actually hear a few bacteria swimming by themselves in the water. However, this study has more important issues. It could be of vital importance in the fight against infectious diseases and antibiotic resistance.

6- Mars Storm

The Perseverance rover carried the first working microphone on Mars. Every few days he recorded only three minutes, but he made some important discoveries, including recording cyclones on the planet. The team had already seen evidence of nearly 100 dust devils since the rover landed, but they consider themselves lucky when they pass by with their microphones on for the first time. Recordings, along with other tools such as barometric pressure readings and time-lapse photography, have helped us better understand the atmosphere and weather of Mars. They learned that the dust devils on Mars have powers similar to those on Earth. That means future astronauts won't have to worry about their gear being blown away by strong winds.

5-A black hole

In space, no one can hear you scream, right? Well, not exactly. It's true that sound needs a medium to travel like air or water, but space is a vacuum and it doesn't have one. So it should be completely silent. But he said in 2022, NASA has proven that this is not entirely true. The universe is not a perfect vacuum chamber, so it is not completely static. Clusters of galaxies contain gas that can provide a medium for the propagation of sound waves. Because of this, NASA was able to record the sound emanating from the black hole. The sound was about 57 octaves below mid-hud, too low for the human ear to hear, so it had to be amplified many times. If it sounds too much to have to magnify a note 57 times to hear it, then you need to magnify it to about 288 trillion times the frequency of the original sound, and 1 trillion has 15 frequencies. Consider there are zeros.

4 deep sea creatures

As the sea level rises, so does the sea temperature. Scientists fear that this could lead to irreversible changes in aquatic ecosystems and even the extinction of some species. We launched a project called Global Library of Underwater Life Sounds. The project has recorded an astonishing range of sounds heard deep in the seafloor, and hopes the recordings will be used for species identification and learning. Dolphins and whales aren't the only creatures that make noise in the ocean. Scientists have heard sea urchins scratching and eating algae on coral reefs. Many of the other sounds recorded have not yet been associated with the species that produced them. Researchers hope algorithms can help match sounds to types

3- Earth's magnetic field

In 2022, scientists at the Technical University of Denmark (DTU) successfully converted magnetic signals measured by the European Space Agency's (ESA) Swarm satellite into sound. The satellite, launched in 2013, picked up the creak while measuring the Earth's magnetic field, which protects Earth's inhabitants from cosmic rays. Data from the magnetic signals were used to create an acoustic representation of the Earth's nuclear magnetic field. In this case, the sounds were not detected directly, but were formed based on the characteristics of data collected by satellites. The resulting audio represents the magnetic field produced by the Earth's core interacting with the solar storm. It is hoped that the research will help scientists understand space weather and increase their knowledge of the Earth's magnetic field.

2-atom

The interaction between atoms and light is well understood in certain areas of physics. The interaction of sound waves with atoms is not well understood. But in 2014, he said, scientists were the first to use sound to "talk" to an atom, but it wasn't artificial. However, like normal atoms, artificial atoms can be energized and emitted in the form of particles. The resulting particles are usually light particles. But researchers at Chalmers University in Sweden have created atoms that can charge up and release energy in the form of sound. One of his researchers described this tone as being the faintest sound that can be detected. Because sound travels much more slowly than light, potentially giving scientists more time to control and observe quantum particles, they hope the work will provide new insights into quantum phenomena.

1-sun

Much is happening inside the Sun, including eruptions, swirling waves, and solar flares. However, the human eye is not sensitive enough to see them, and even with the visual technology that scientists have, they cannot see what is going on inside. Use the generated vibrations to make sounds to learn more about the center of the solar system. The study was led by the European Space Agency and his NASA, which have been tracking vibrations produced by the movement of the sun for over 20 years. Vibration data is specifically cleaned to remove spacecraft sounds (preferably artifacts!). Then he increases the frequency by a factor of 42,000 to make it audible to the human ear. You can actually hear the slightly eerie pulsating hum of our closest star on NASA's website.
