What does an atom bomb sound like?
There is at least some testing footage from the era that features sound. It is jarring to hear. The boom is more like a shotgun than a thunderclap, and it's followed by a sustained roar. Here's one example, from a March 1953 test at Yucca Flat, the nuclear test site in the Nevada desert.

How far can you hear an atomic bomb?
The flash was accompanied by a rush of heat and was followed by a huge pressure wave and the rumbling sound of the explosion. Curiously enough, this sound was not distinctly noted by those who survived near the center of the explosion, although it was heard as far as 15 miles away.

What is the loudest thing in the world?
The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.

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.

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.

How loud is a whisper?
Common Sources of Noise and Decibel Levels
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.

Can you shoot down a nuke?
Short answer: It's very unlikely. As you read above, causing a nuclear bomb to detonate requires a precise orchestration of events, without which the chain reaction does not initiate and the bomb doesn't detonate.

How quiet is it in space?
Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would hear nothing.

How loud is 1100 decibels?
40 decibels is 10 times more powerful than 30 decibels. Each time the decibel number goes up by 10, the power of the sound is multiplied by 10. The number 1100 is like starting with 10 decibels, and adding 10 on 109 times. That means 1100 is 10109 times more powerful than 10 decibels.

The resulting inferno, and the blast wave that follows, instantly kill people directly in their path. But a new study finds that some people two to seven miles away could survive—if they're lucky enough to find just the right kind of shelter.How painful is a nuclear bomb? ›
People may experience moderate to severe skin burns, depending on their distance from the blast site. Those who look directly at the blast could experience eye damage ranging from temporary blindness to severe burns on the retina.What does atomic bomb feel like? ›
The effects are similar to the effect of a two-second flash from an enormous sunlamp. Since the thermal radiation travels at roughly the speed of light, the flash of light and heat precedes the blast wave by several seconds, just as lightning is seen before thunder is heard.What material can survive a nuclear bomb? ›
Once you survive the initial blast, you're going to want as much dense material — concrete, bricks, lead, or even books — between you and the radiation as possible.

The ozone layer would diminish due to the radiation, ultimately becoming as much as 25% thinner for the first five years after the event. After 10 years, there would be some recovery, but it would still be 8% thinner. This would result in a rise in skin cancer and sunburns.
In a study published in Physics of Fluids, scientists simulated an atomic bomb explosion to determine the best and worst places to be in a concrete-reinforced building during such an event. The safest place: the corners of a room, author Ioannis Kokkinakis of Cyprus' University of Nicosia said in a statement.What weapon is more powerful than nuclear? ›

The walls of your home can block much of the harmful radiation. Because radioactive materials become weaker over time, staying inside for at least 24 hours can protect you and your family until it is safe to leave the area. Getting inside of a building and staying there is called “sheltering in place.”How long does radiation last in an area after nuclear bomb? ›
