# Quick answer: How Many Decibels Can Kill You?

## How many decibels can a human take?

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..

## 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.

## Why is 194 dB the loudest sound possible?

The loudest a sustained sound can possibly be on Earth’s surface is 194 dB—which is when the amplitude of the sound wave is so intense that the low pressure part is a perfect vacuum (the wave alternates between double the normal atmospheric pressure and no air at all—not something you want to be present for).

## What is the loudest sound possible?

A barometer at the Batavia gasworks (100 miles away from Krakatoa) registered the ensuing spike in pressure at over 2.5 inches of mercury. That converts to over 172 decibels of sound pressure, an unimaginably loud noise.

## Is sound louder underwater?

Sound that’s generated underwater stays underwater; very little sound passes from water to air. … But if you put your head under the water, the sound becomes much louder. You also feel more of a sound when you’re underwater. Above the surface, the sound waves only vibrate your eardrum (unless the sound is very loud).

## Can a sperm whale click kill you?

In air, the sperm whale would still be extremely loud, but significantly less so — 174 decibels. That’s roughly equivalent to the decibel levels measured at the closest barometer, 100 miles away from the Krakatoa eruption, and is loud enough to rupture people’s ear drums.

## Does the sun make noise?

Does the Sun make noise as it burns? The surface of the Sun produces sound waves because the surface is convecting and this produces pressure waves that travel into the inner corona. … But yes, the surface does produce sound waves, but they have very low wavelengths measures in hundreds of miles!

## How loud is 1100 decibels?

1100 decibels is preposterous. 20 db is ten times as loud as 10 db. To the Human ear, it sounds about twice as loud.
