# Quick Answer: What Is The Loudest Thing In The Universe?

## How loud is 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..

## Can loud noises kill you?

Yes. Sound can absolutely kill you if it’s loud enough. The long answer requires looking at what sound really is. Sound is created by a pressure wave which vibrates particles as it travels in an accordion-like manner.

## How many dB is a gunshot?

140How loud is a gunshot? Decibel levels for firearms average between 140 and 165 dB.

## How many decibels is too 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.

## Can a sonic boom kill you?

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

## How loud is a nuke?

All noise is measured in decibels, so how loud is the biggest of man made bangs? the bomb can produce an overpressure corresponding to 278 decibels. 200 decibels is enough to cause instant death, and 278 decibels is about 10 million times greater sound intensity. …

## How loud is 1000db?

Now 194 decibels is a LOUD sound. An estimated 180 decibel sound of the Krakatoa volcano eruption was heard as far as 3,000 miles away and blew out eardrums up to 40 miles away! For days our sensors could detect the waves rippling across the atmosphere!

## Can we create a black hole?

To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light.

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

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.

## How loud is 1100 decibels?

A 1100 decibel sound is 10 93 times more powerful than 172 decibels. That is an inconceivably huge number. By comparison, the number of atoms in the observable universe is estimated to be around 10 80, and 10 93 is ten trillion times greater than that.

## Can silence kill you?

It can’t be seen or heard; can take place indoors or outside; it’s not biological, environmental or radiation, but it can make you sick or kill. Your body reacts to sound, a train or plane passing by or your being too close to speakers can cause your body to shudder. …

## Can a sperm whale kill you with sound?

Sperm whales are the loudest mammals on the planet, with vocalizations reaching an astonishing 230 decibels. … At around 150 decibels your eardrums will burst, and the threshold for death is estimated to be in the range of 180 to 200.

## How loud is a supernova?

That loudest sound is about 194 dB at 1 atmosphere: it is the maximum deviation from the ambient pressure to a vacuum. So, to answer the question, 194 dB. … The extra energy above creating the vacuum is converted to a shockwave, and not an increase in decibels.

## What is the loudest sound a human can tolerate?

0 decibel is the so-called hearing threshold for the human ear. While we can hear more than 140 decibels, it is too painful for our ears and if you expose yourself to such a loud noise you are at extremely high risk of permanent damage to your hearing. The table blow shows how loud sound is.

## 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.

## What frequency can kill you?

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.

## Is it possible to make a sound louder than 1100 dB?

1100 decibels is 906 decibels more than that. That’s not possible for a normal sound wave but would be possible for a shock wave where you get a pressure of many atmospheres that rushes through the atmosphere at faster than the speed of sound.

## Why is 194 dB the loudest sound possible?

A note on the loudest possible sound in air A sound of 194 dB has a pressure deviation of 101.325 kPa, which is ambient pressure at sea level, at 0 degrees Celsius (32 Fahrenheit). Essentially, at 194 dB, the waves are creating a complete vacuum between themselves.
