How much is 1100 dB?
1100 dB = 10^98 joules.
10^98 J of energy > 4 x 10^69 J of the universe’s energy.
Due to Einstein’s law of energy and mass, 10 ^ 98 J = 1.118 x 10^80 kg of mass.
With a mass of that much, the radius of the event horizon = 1.747 x 10^37 light years..
What’s the loudest A human can shout?
‘Quietttt!!! No other than their teacher, who just happens to have the world’s loudest shout. Miss Flanagan entered the record books back in 1994 with a thunderous rendition of ‘quiet!’ The shout clocked up an earth-shattering 121.7 decibels, setting a world record.
What is the loudest animal in the world?
Blue whalesThe blue whale is the loudest mammal of them all, with vocalizations that reach 188 decibels. Blue whales don’t have songs as complex as those of humpback whales, but their low-frequency “pulses”—some below the range of human hearing—have been recorded more than 500 miles (805 kilometers) away.
What is the loudest car in the world?
Ferrari Enzo- Decatted Ferrari Enzo!
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 is the 3dB rule?
3dB rule and maximum exposure to noise To put it in context, a worker exposed to a continuous sound intensity level of 83dB(A) for one hour would be exposed to the same amount as someone exposed to an 80dB(A) level for two hours.
Can a black hole die?
Hawking radiation reduces the mass and rotational energy of black holes and is therefore also known as black hole evaporation. Because of this, black holes that do not gain mass through other means are expected to shrink and ultimately vanish.
How loud is 92 decibels?
Normal conversation is about 60 dB, a lawn mower is about 90 dB, and a loud rock concert is about 120 dB. In general, sounds above 85 are harmful, depending on how long and how often you are exposed to them and whether you wear hearing protection, such as earplugs or earmuffs.
How loud is a sonic boom?
Sonic booms generate enormous amounts of sound energy, sounding much like an explosion; typically the shock front may approach 100 megawatts per square meter, and may exceed 200 decibels. … When an aircraft is near the sound barrier, an unusual cloud sometimes forms in its wake.
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.
How many decibels can kill a human?
German researcher Jurgen Altmann showed that a blast of 210 decibels or more affects the inner organs — the lungs — and could cause internal injury that could lead to death. A blast will impact the body, and would do so very violently.
Is 48 dBA a quiet dishwasher?
Noise Level If finding the quietest dishwasher available is a concern for you, check the decibel level. A rating of 45 or lower is virtually silent — similar to a low discussion in a library or quieter. Decibel levels between 45 and 50 sound similar to a rainfall.
What frequency can humans hear by age?
Though a ‘normal’ audible range for loudness is from 0 to 180dB, anything over 85dB is considered damaging, so we should try not to go there. As we age, it’s the upper frequencies we lose first. So by the time we hit middle-age, we can expect to hear up to around 14,000Hz.
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 on earth in decibels?
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.
Can a sound be so loud it kills 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. Alternatively, your lungs might simply burst from the increased air pressure. … High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage.
How many dB is a gunshot?
How loud is a gunshot? Decibel levels for firearms average between 140 and 165 dB.
