200 decibels (dB) is an incredibly destructive, physically impossible sound in Earth's atmosphere, equivalent to an explosive shockwave that would instantly kill a person by rupturing lungs, tearing tissue, and causing immense pressure changes, far beyond the pain threshold (around 120 dB) or lethal levels (180-200 dB). It's a level reached by natural phenomena like sperm whale clicks (in water) or rocket launches, but in air, sound waves max out around 194 dB before becoming a shockwave.
While 180 to 200 decibels (dB) on land is loud enough to be deadly, it wouldn't be lethal in the ocean.
Tiger Pistol Shrimp
This shrimp is native to the Mediterranean and it apparently tops the list as the loudest living animal, due it the noise it makes topping over 200 dB. This is louder than a gunshot! However, due to it living under the sea, they are much quieter, around 120-130 dB.
A sound level of 300 decibels (dB) is theoretically impossible to achieve and far beyond any natural sound we experience.
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. A 1-Ton TNT Bomb: An explosion from this bomb would measure 210 dB.
At 300 decibels, the sound would not just be deafening; it would be fatal. Such an extreme noise level would generate shockwaves capable of causing severe damage to structures and the human body, leading to instant hearing loss, internal injuries, and potentially fatal outcomes.
The energy levels of a 1000 decibel sound are in in the neighborhood of Big Bang levels. Decibels describe pressure and it's a logarithmic scale. So, imagine the energy involved in a 100 decibel noise. (like a lawnmower up close or 1000 feet from a jet engine).
The loudest human-made sounds: Nuclear Bomb (224 dB), Rocket launch (204 dB). And clocking in at 260 underwater decibels is the seismic blast, part of a process for exploring for oil and gas in the ocean.
Yes, in theory, a sound louder than 1100 dB could create a black hole, though it's not physically possible to produce such a sound on Earth. The immense energy associated with a sound of that magnitude, if concentrated in a small enough area, would create enough gravity to form a black hole.
Humans can hear decibel levels between 0 dB (the hearing threshold) and 130 dB (the pain threshold) and sound frequencies between 20 Hz and 20,000 Hz or 20 kHz. Sounds under 20 Hz are known as infrasounds and sounds above 20 kHz are known as ultrasounds.
Chain saws typically are measured at 125 decibels (dBA) and heavy equipment at 95-110 decibels (dBA). Continuous exposure to these levels may exceed the permissible amount allowed in Table G-16 of OSHA's Occupational Noise Exposure Standard [1910.95]. Even short term exposures to these levels can cause hearing loss.
1. Sperm whale. Pod of sperm whales swimming off the coast of Sao Miguel, Azores. Sperm whales (Physeter macrocephalus) are regarded as the loudest animals on the planet, capable of making sounds up to 230 decibels.
For residential environments, the accepted decibel level is lower. Any noise exceeding 70 dB is considered disturbing. Residential limits usually start at 60 or 55 dB (the equivalent noise of a regular vacuum cleaner). Time limits usually apply after 10 pm and until 7 am.
The volcanic explosion of Krakatoa (1883) is considered the loudest modern sound ever heard, an estimated 310 decibels. The catastrophic blast, which occurred on Rakata Island, Indonesia, was heard as far as 3,000 miles (4,800 km) away.
Converting the energy of 1,100 decibels to mass yields 1.113x1080 kg, meaning that the radius of the resulting black hole's event horizon would exceed the diameter of the known universe. Voila! No more universe.
Riveting machine (110 dB); live rock music (108 - 114 dB). Average human pain threshold. 16 times as loud as 70 dB. Jet take-off (at 305 meters), use of outboard motor, power lawn mower, motorcycle, farm tractor, jackhammer, garbage truck.
The "two-man rule" in nuclear operations is a security protocol requiring at least two authorized, trained personnel to be present and cooperate to perform critical tasks, like accessing or launching nuclear weapons, preventing any single person from acting alone to prevent accidental or unauthorized use, often involving separate keys, codes, or physical actions for each person. This system ensures checks and balances, seen in missile silo crews turning separate keys or submarines requiring dual authentication, creating a fail-safe against individual error or malice.
The loudest sound ever made by humans was the detonation of the Tsar Bomba, a nuclear bomb created and detonated by the Soviet Union in 1961. It was the most powerful nuclear weapon ever created and tested.
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.
On average, a healthy young person can hear frequencies from 20 Hz to 20,000 Hz, but as you age, the upper part of the frequency range starts to decrease. A person in their 20s will usually be able to hear up to 17,000 Hz, and this decreases to around 12,000 Hz once they reach their 50s.
YOU'RE BEING TOO LOUD: Ear doctors recommend wearing hearing protection for the Taylor Swift concert (and any concert) which can hit more than 100 decibels. At that level, it can cause damage to your ears both in the short term and long term.
How loud can something be? Once you get to a certain level (194 decibels, to be precise), there comes a point where the low-pressure regions are completely empty – there are no molecules in there at all. The sound can't get 'louder' than that, technically.
