A normal voice level is between 60-70 dB. A raised voice is between 65-75 dB. A very loud voice is between 75-85 dB. A shouting voice is above 85 dB.
120 – 140 decibels: Such as, a rock concert, auto racing, or a hammer pounding a nail. 125 – 155 decibels: Like, firecrackers or fireworks, or a jet engine. 170 – 190 decibels: For example, a shot gun blast or a rocket lift off.
70 dB is in the middle of this decibel range. It is equivalent to the sound level of a regular washing machine. It is also equivalent to the noise level in an office environment or inside a car driving at 60 mph.
You can listen to sounds at 70 dBA or lower for as long as you want. Sounds at 85 dBA can lead to hearing loss if you listen to them for more than 8 hours at a time. Sounds over 85 dBa can damage your hearing faster.
Sounds between 170-200 dB are so intense that they can cause lethal issues like pulmonary embolisms, pulmonary contusions, or even burst lungs. As for exploding heads, you can expect that from sounds above 240 dB. However, such high intensity sounds are very rare.
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.
A gunshot is typically around 140 to 190 decibels. In comparison, a jet taking off is approximately 150 decibels. Decibels measure the intensity of sound. The higher the number, the louder the sound and the more damaging it can be to your hearing.
What's important to know is that 100 dB are not twice as loud as 50 dB. Perception of volume is always subjective and depends on one's own hearing but generally speaking, an increase of 10 dB roughly corresponds to the perceived volume doubling in intensity. Thus, 60 dB are perceived as twice as loud as 50 dB.
The intermittent and piercing nature of a dog's bark can be very disruptive for close neighbours. A dog's bark can reach 90 decibels.
The loudest fart ever recorded occurred on May 16, 1972 in Madeline, Texas by Alvin Meshits. The blast maintained a level of 194 decibels for one third of a second.” Then there's the Guiness Book of World Records……
With energy as great as 1100 dB, it would create enough gravity to cause a black hole to form, and an incredibly large one at that. Decibels are a logarithmic unit. That means 20 decibels isn't 2 times more powerful than 10 decibels, it's 10 times more powerful.
The outside of aircraft engines (around 140 dB at takeoff) and conditions on other aircraft may have higher or lower noise levels.
a sound greater than 1,100 decibels would unleash enough energy to act like an equivalent quantity of mass. Through Einstein's laws of relativity, this mass would create enough gravity enough to form a black hole. Shortly thereafter, everything in existence would disappear in a crush of sound.
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!
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.
Car horn: 110 decibels. Nightclub: 110 decibels. Ambulance siren: 112 decibels.
As a rule of thumb, babies should not be exposed to noise levels over 60 decibels. The noise level recommended for hospital nurseries is actually lower, at 50 dB. For reference, a quiet conversation is between 50 and 55 dB and an alarm clock is 80 dB.
This sound, measured at an incredible 310 decibels was made in 1883 by the eruption of Krakatoa, a volcano in the Sunda Strait of Indonesia. The eruption could be heard in locations as far as western Australia and caused horrific tsunamis and tidal waves.
The average noise volume at a concert or festival is around 100 decibels.
These range in intensity from 157 dBP (peak unweighted decibels) for a 5.56mm M16 rifle to 183 dBP for a 105mm towed howitzer. Warfighters are required to wear hearing protection during training and should do so during combat. Military regulations require double hearing protection for some exposures.
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.
But if we could hear the constant roar, it'd be pretty loud, even from here. One heliophysicist crunched the numbers and estimates the noise would be around 110 decibels, or about the same volume as speakers at a rock concert.
Based on our white noise measurements for the first test, Apple AirPods Max are the loudest AirPods, reaching 108.3dB at 100%. That means that listening to anything at 100% volume for more than 2 minutes can result in hearing damage.
