A black hole itself is silent in the vacuum of space, but the surrounding gas and matter create incredibly powerful, low-frequency pressure waves that are millions of times too deep for humans to hear, though NASA has converted them to eerie, groaning sounds by increasing the frequency (sonification). These sound waves, like those from the Perseus black hole, contain immense energy, equivalent to billions of Suns, making them "loud" in energy but inaudible without translation.
Apparently, a sound of 1,100 decibels would create so much energy, it would act as a immensely high quantity of mass. This would, in turn, create enough gravity to form an extremely large black hole!
turns out the answer is yes, if you have a loud enough sound. let's say we're able to create a sound of 1100 decibels. now, that sound have a heck of a lot of energy, to the tune of 10 to the 98 Watts per meter squared.
For reference, under normal conditions the loudest possible sound (on Earth) is 194 dB. A sound of 1000 dB would be loud enough to create a black hole larger than the galaxy. We wouldn't be able to get a bark that loud even if we covered every inch of earth with clones of champion barker Charlie.
For the first time in history, earthlings can hear what a black hole sounds like: a low-pitched groaning, as if a very creaky heavy door was being opened again and again.
While space remains dead silent to our ears, it buzzes with electromagnetic activity that can be translated into mesmerizing soundscapes by scientists. These sonified signals give us a way to “hear” the cosmos and understand celestial environments in ways we never imagined.
For you to destroy the galaxy, you need to expend enough energy to destroy the galaxy. There are no shortcuts in physics. A 1,100 dB sound would require an astronomical amount of energy, beyond comprehension.
The loudest human-made sounds: Nuclear Bomb (224 dB), Rocket launch (204 dB). And clocking in at 260 underwater decibels is the seismic blast, part of a process for exploring for oil and gas in the ocean.
For optimal sleep, the level inside your house at night should not exceed 30dB. For the prevention of adverse health effects, you should not be exposed to outside noise pollution of 40 dB. Noise levels should not exceed 45dB for a considerable amount of time.
Chain saws typically are measured at 125 decibels (dBA) and heavy equipment at 95-110 decibels (dBA). Continuous exposure to these levels may exceed the permissible amount allowed in Table G-16 of OSHA's Occupational Noise Exposure Standard [1910.95]. Even short term exposures to these levels can cause hearing loss.
If a sound is 100 dB at the source, it will be 94 dB at 1 meter, 88 dB at 2 meters, and so on. Therefore, you will generally be able to hear a 100 dB sound at a maximum of 16 meters.
YOU'RE BEING TOO LOUD: Ear doctors recommend wearing hearing protection for the Taylor Swift concert (and any concert) which can hit more than 100 decibels. At that level, it can cause damage to your ears both in the short term and long term.
Any noise over 120 decibels, for any length of time, will cause hearing damage and elicit physical pain in your ear. Additionally, noises that register at 150 decibels will rupture a human eardrum.
The Sun is incredibly loud—its surface roars at an estimated 100 decibels, comparable to a rock concert. Yet, we never hear it because space is a vacuum, and sound cannot travel without a medium like air, water, or solid matter.
Black Hole Sound. The lowest pitch sound waves ever discovered have been sonified for the first time. In 2003, sound waves were a detected in x-ray images of the hot gas surrounding the Perseus cluster. Their pitch is a Bb, about 57 octaves below middle C making them the lowest frequency sound waves ever discovered.
A Black Hole That Plays a Cosmic “Note” When people imagine black holes, they often picture silent monsters devouring everything around them. Yet in 2003, NASA's Chandra X-ray Observatory revealed something utterly unexpected: a black hole was not silent at all.
😱 Did you know that the loudest human shout ever recorded reached an astonishing 129 decibels? While the average human shout typically ranges between 70 and 90 decibels, exceptional individuals can achieve much higher levels through training, technique, and unique vocal anatomy.
Eliminate caffeine 10 hours before sleep. Cut alcohol 3 hours before bed. Stop working 2 hours before bed. Stop screen time 1 hour before bed.
3 dB rule: A 3 dB gain means twice (x2) the power. A 3 dB loss means half the power. For example, a system with 40 watts of input power and a 6 dB insertion loss will only have 10 watts of output power. dB: Decibel, a logarithm (equal to 10 times) ratio of the difference between two values.
If we're talking about sounds within the human hearing frequency range (between 20 and 20,000 Hz), high-intensity sounds above 150 decibels can burst your eardrums, while sounds above 185 dB can impact your inner organs and cause death.
The "Two-Man Rule" in nuclear operations is a critical security protocol requiring at least two authorized, trained personnel to be present and mutually verify actions for handling, arming, or launching nuclear weapons, preventing accidental or unauthorized use by a single individual, implemented through separate keys, codes, or actions. This ensures checks and balances, as seen in missile silos (two keys turned simultaneously) or submarines (CO and XO agree and authenticate codes), making a lone rogue actor unable to initiate a launch.
The Krakatoa volcanic eruption: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB. It was so loud it was heard 3,000 miles (5,000 km) away. 3. A 1-Ton TNT Bomb: An explosion from this bomb would measure 210 dB.
About 95% of the universe is "invisible" because it's composed of dark matter (around 27%) and dark energy (around 68%), which don't emit, absorb, or reflect light, unlike the normal matter (stars, planets, us) that makes up the visible 5%. Dark matter's presence is inferred through its gravitational pull on visible galaxies, while dark energy is a mysterious force causing the universe's accelerated expansion.
You're at risk of hearing damage after just 15 minutes when you're in a nightclub which plays music at the average volume of 100dB, if you don't use earplugs to protect your ears. For sounds of 110–120dB, even a very short exposure time can cause hearing damage.
Over time, many of these smaller galaxies are slowly being torn apart, their stars stretched into streams and rivers that eventually blend into the Milky Way itself. This process of galactic cannibalism has been happening for billions of years, and it is one of the reasons our galaxy has grown so massive.
