THE QUIETEST PLACEONEARTH The loudest place on earth is in the cockpit of a Formula One racing car where it produces over 140 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. 3.
1. Dhaka (Bangladesh) – 119dB. In April 2022, the United Nations Environment Programme (UNEP) named Bangladesh's capital the world's noisiest city. In 1999, the World Health Organisation published guidelines stating that noise levels above 70dB over a prolonged period can lead to a greater chance of hearing loss.
A whisper is between 20-30 dB. On the other hand, a human scream can reach decibel levels between 80 and 125 dB.

The report revealed that the South Asian region which includes India, Pakistan, Bangladesh, Sri Lanka, and Nepal is the noisiest in the world with Latin America and Europe as the quietest regions.
Italy and the United States top the list with the highest average noise exposure in the world.
These speakers, driven by pressurised nitrogen gas, can saturate the room with 163 dB of continuous noise for up to 10 minutes. The biggest speakers generate a tone at 25 Hz, which is just above the lowest note humans can hear, while the smaller speakers go as high as 250 Hz.
Decibel levels:
A normal conversation – 60 dB. A noisy restaurant – 70 dB. An electric drill – 95 dB. Jill Drake, a teaching assistant who in 2000 won the Guinness World Record for the loudest individual's shout – 129 dB.
Tokyo, Japan
It has a population of 35 million people. The noise pollution level of Tokyo is at 90 decibels and sometimes higher. The main source of noise in Tokyo is construction sites. The noise made by equipment in construction sites can be heard all over the city.
Mumbai, India
Known as the entertainment, commercial fashion and financial capital of India, Mumbai's severe city traffic and overpopulation can lead to noise of over 100 decibels, and it has been declared the noisiest city in the world in previous studies.
Hyperacusis is a type of reduced tolerance to sound. People with hyperacusis often find ordinary noises too loud, while loud noises can cause discomfort and pain. The most common known causes of hyperacusis are exposure to loud noise, and ageing.
This sensitivity to noise is known as hyperacusis, a condition that arises from a problem in the way the brain processes noise. When a sufferer comes to dread social settings due to the noise, it can become a mental health trigger.
Top of our list of quietest places on Earth is the place described as “where sound goes to die”. This Microsoft research lab in the city of Redmond, Washington, is officially the quietest place on Earth, according to Guinness World Records.
Guangzhou, China, ranked as having the worst levels of noise pollution in the world, followed by Cairo, Paris, Beijing and Delhi.
A recent study of 21 different countries found that Brazil is the noisest between the sheets, leading it to be officially declared the country that climaxes the loudest.
After a statistical processing, we can conclued that people consider India as the noisiest contry in the World.
With active populations, road traffic, industry, and construction, cities are expectedly noisy places.
We are in absolutely no danger from black holes. They're a bit like tigers – it's a bad idea to stick your head in their mouth, but you're probably not going to meet one on your way to the shops. Unlike tigers, black holes don't hunt. They're not roaming around space eating stars and planets.
DeForest pegs the sun's din on Earth at around 100 decibels, a bit quieter than the speakers at a rock concert. That's during the day, of course. At night, as we turn away from the sun, the roar would fade.
The enormity of the sun's surface paired with its capability of generating of tens of thousands of watts of sound energy per meter makes the sun astronomically loud.
In Japan, being quiet or calm is considered as a virtue which comes from Samurai period, so in the place, Japanese people tend not to be fond of being too friendly, especially when they talk with strangers.
