# Question: What Is The Loudest Thing In The Universe?

## Can a sperm whale kill you with sound?

Sperm whales are so loud that their clicks are capable of killing a human within their vicinity, says one science and adventure journalist.

“These clicks are so powerful in the water that they can blow out your eardrums easily, and they can actually vibrate a human body to death,” he said..

## What is blue noise?

Blue noise is a noise color with a spectral density (power per hertz) that is proportional to its frequency. … Because blue noise is biased toward higher frequencies, it sounds like a high-pitched hiss completely lacking any bass.

## How many decibels does it take to destroy the universe?

Absent magical amulets or alliances with a powerful alien race, how could you pull it off? It may be possible to destroy everything with a loud enough sound. NASA estimates the mass energy of the universe at 4×1069 joules. But that number that is considerably smaller than the energy created by 1,100 decibels of sound.

## What frequency can kill you?

Sounds around 19 hz match the resonant frequency of the human eyeball, with reports of apparitions as detailed by the Coventry Telegraph newspaper. The most dangerous frequency is at the median alpha-rhythm frequencies of the brain: 7 hz. This is also the resonant frequency of the body’s organs.

## How loud can a human yell?

Human screams can be quite loud, possibly exceeding 100 dB (as of March 2019, the world record is 129 dB!) —but you probably want to avoid that because screams that loud can hurt your ears! You should also have found sound levels drop off quickly as you get farther from the source.

## Is 130db loud?

The decibel (abbreviated dB) is the unit used to measure how loud a sound is. A sound 10 times more powerful is 10 dB. … A sound 100 times more powerful than near total silence is 20 dB.

## What is the 3dB rule?

3dB rule when measuring noise at work When you measure noise levels with a noise meter, you measure the intensity of noise in units called decibels, expressed as dB(A). … It is based on orders of magnitude, rather than a standard linear scale, so each mark on the decibel scale is the previous mark multiplied by a value.

## How many dB is a gunshot?

Firearms Are Loud Exposure to noise greater than 140 dB can permanently damage hearing. Almost all firearms create noise that is over the 140-dB level. A small . 22-caliber rifle can produce noise around 140 dB, while big-bore rifles and pistols can produce sound over 175 dB.

## How loud is a supernova?

If, hypothetically, there were air filling the universe, then suddenly things would get very loud. Forget the terrifying concept of the sound of a supernova—just the dumb sun sitting there hanging out would ring in at an astounding 290 dB.

## What is a black noise?

Black noise is an informal term used to describe lack of noise. It refers to complete silence or mostly silence with bits of random noise. Some people feel most relaxed when there is little to no noise. …

## Can whales kill you with sound?

A sound of 180dB is enough to cause drastic cell death in your ears, but the most powerful sperm whale clicks will not merely deafen you: they can vibrate the fragile human body to pieces.

## CAN 1100 dB create a black hole?

With energy as great as 1100 dB, it would create enough gravity to cause a black hole to form, and an incredibly large one at that. Decibels are a logarithmic unit. That means 20 decibels isn’t 2 times more powerful than 10 decibels, it’s 10 times more powerful.

## What is the world’s loudest sound?

4. 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.

## Can 7hz kill you?

This is also the resonant frequency of the body’s organs. At high volumes, infrasound can directly affect the human central nervous system causing disorientation, anxiety, panic, bowel spasms, nausea, vomiting and eventually organ rupture, even death from prolonged exposure.

## Why is 194 dB the loudest sound possible?

Strictly speaking, the loudest possible sound in air, is 194 dB. The “loudness” of the sound is dictated by how large the amplitude of the waves is compared to ambient air pressure. … Essentially, at 194 dB, the waves are creating a complete vacuum between themselves.

## What does white noise do to your brain?

Based on their review, the authors assert that white noise may have negative consequences on central auditory function and brain functioning in general. They recommend that white noise should be avoided as a treatment for tinnitus. The authors cite a handful of studies showing various effects on brain function.

## Is 70 dB loud?

Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.

## What’s the loudest thing in the universe?

Going by this the Sound made by the Krakatoa volcanic eruption in 1883 was so loud it ruptured eardrums of people 40 miles away, travelled around the world four times, and was clearly heard 5,000 kilometers away. This is hailed as the loudest noise ever.

## Can a loud sound kill you?

The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. … High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage.

## Can humans create a black hole?

“With about as much confidence as we can say anything in science, this is completely impossible.” To start with, theoretical physicist Stephen Hawking calculated all black holes should lose mass over time, giving it off as so-called Hawking radiation.

## Is it OK to leave white noise on all night?

As with swaddling, white noise should not be used 24 hours a day. You’ll want to play it to calm crying episodes and during naps and nighttime sleep (start the sound quietly in the background during your sleepy-time routine, to get your sweetie ready to glide into dreamland).
