Where is sound the loudest?
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.

In fact, at this level of intensity, sound waves would be so powerful that they could potentially cause physical harm to the human body, including rupturing internal organs. It is important to note that 300 decibels is not a level of sound that is commonly found in the natural world.
Is 300 decibels possible?
Loud appliances such as a vacuum cleaner or power tools could exceed 80 dB. 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!

An anechoic chamber has an impressive silence because it simultaneously presents two unusual sensations: Not only is there no external sound, but the room puts your senses out of kilter. Through their eyes, visitors obviously see a room, but their ears hear nothing that indicates a room.
What's the most silent thing?
Any sounds below the threshold of 0 dBA is undetectable by the human ear. And at such a low decibal level, the environment becomes so disconcerting that people have actually started to hallucinate. "When it's quiet, ears will adapt. The quieter the room, the more things you hear.
Why do you hallucinate in the world's quietest room?
The lowest hearing decibel level is 0 dB, which indicates nearly total silence and is the softest sound that the human ear can hear. Generally speaking, the louder the sound, the higher the decibel number.
What is the quietest sound a human can hear?
0dB is LOUD
Put simply, home theatre amplifiers use 0db as a reference level for how much volume they can output before distortion becomes audible (or the loud parts of the sound wave are clipped).
Why is 0 dB loudest?
The lowest decibel a human can hear is 0 dB. In some exceptional cases, humans can hear sounds down to -15 dB. 0 dB sounds are very soft and barely perceivable by the human ear. To understand just how soft, imagine that a whisper is 30 dB and 30 dB is 1,000 times louder than a 0 dB sound.
Can you hear 0 dB?
Scientists have determined that 0 dB is the lowest sound perceived by the human ear. This does not mean total silence, though. 0 dB means that the sound is so low that the sound pressure level is equal to the one of the reference level.
What does 0 dB sound like?
On Earth, in our atmosphere at normal pressures, etc., 1000 dB is impossible. The most the pressure variation can possibly be is the standard air pressure at sea level, about 101.3 kPa, which equates to about 194 dB. You would nor perceive the loudness of such a sound as this intensity is enough to kill you instantly.

How loud can a human clap?
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.
How loud is a whisper?
The average decibel level of human speech is estimated between 55 and 65 decibels. A whisper is considered the lowest decibel level of human speech. A whisper is between 20-30 dB. On the other hand, a human scream can reach decibel levels between 80 and 125 dB.

After some calculations, he explained that the Sun would theoretically blare out a noise of around 100 decibels, almost as loud as standing next to a speaker at a rock concert or busy nightclub. That's pretty remarkable when you consider the Sun is 150 million kilometers (over 93,000,000 miles) away from us.
How loud is the sun on Earth?
In terms of sound in earth's atmosphere, anything over 194 dB is a shock wave. 10,000 dB would equate to an overpressure of very nearly 5 x 10^499 atmospheres - quite sufficient I imagine to destroy the earth; though what you would use to create such a shock wave defies imagination.
How loud is 10,000 decibels?
Loud sounds with intensities above 194dB can start damaging our eardrums, so 300dB is simply incomprehensible in terms of its destructive power. Such a sound level would create shockwaves of incredible force, capable of demolishing buildings and causing immense destruction within a considerable radius.
What would 300dB do?
A sound of 500 decibels is not physically possible. includes a table relating sound in decibels to power in Watts. A Saturn V rocket emits a sound of 200 dB, or 100 million Watts. An increase of 10 dB corresponds to a factor of 10 in power, so 210 dB is 1 billion Watts.

In the case of sounds we can hear, to actually kill you, scientists believe that loud a sound must exceed 185 or even 200 dB. From 150 dB on, sounds can start affecting your inner ear and then your inner organs. In such cases, sound can cause life-threatening internal injuries and even death.
