Audio devices and mobile phones including iPhone have a sound level of 100 dB or louder. iPhones can produce a maximum of 115 decibels (software limits European iPods to 100 dB; U.S. models have been measured higher), the equivalent of attending a rock concert amplification.
The softest sounds are made at zero dB, and the loudest are 120 dB. Normal speech is around 50 dB. Phones for the hard of hearing have three levels of amplification.
A normal conversation: 60-70 dB. Open office noise: 65-75 dB. An alarm clock: 70-80 dB.
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. Loud noise above 120 dB can cause immediate harm to your ears.
85 – 100 decibels: For example, a hair dryer, blender, power lawn mower, forklift, or subway train. 100 – 120 decibels: For example, a bulldozer, impact wrench, or motorcycle. 120 – 140 decibels: Such as, a rock concert, auto racing, or a hammer pounding a nail.
A small . 22-caliber rifle can produce noise around 140 dB, while big-bore rifles and pistols can produce sound over 175 dB. Firing guns in a place where sounds can reverberate, or bounce off walls and other structures, can make noises louder and increase the risk of hearing loss.
A measurement of –1,000,000,000 decibels would represent a sound that is 10¹⁰⁰⁰⁰⁰⁰⁰⁰⁰ fainter than the threshold of human ability to hear.
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.
Average 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.
The level of noise that starts to have an effect on sleep is around 40dB. The noise of snoring can range from about 50dB to 100+dB.
Ringtones: How loud is too loud? Noise limits for ringtones vary with the distance from phone to ear. Studies found that ringtones average 60 decibels from five meters away. At one meter away, phones ring at 76 decibels, and the sound intensity can rise up to 128 decibels when a mobile phone is placed beside the ear!

This noise level is under the limits recommended by the Environmental Protection Agency according to which if you keep your exposure to noise under 70 decibels over 24 hours you can prevent hearing loss or damage. However, if you are trying to sleep or study, the ideal noise level should be under 40 decibels.
Decibel X. Turns your smartphone into a pre-calibrated, accurate and easily portable sound level meter. It has a standard measurement range from 30 to 130 dB, boasts many features for measuring the intensity of sound around you, all of which is built into a nicely-designed, intuitive user interface.
100 decibels is a suitable level for headphones but for no more than 15 minutes. Exposure exceeding 15 minutes may cause hearing damage or hearing loss.
80 decibels is fairly loud. It's equivalent to the noise of a busy downtown street. Being loud, it is a noise level that may harm your hearing if you are exposed to it for longer periods (more than 8-10 hours/day).
Normal hearing usually returns within a few hours to a few days. This is because the hair cells, similar to blades of grass, will bend more if the sound is louder. But they will become straight again after a recovery period. However, if loud noise damaged too many of the hair cells, some of them will die.
At 194 dB, the energy in the sound waves starts distorting and they create a complete vacuum between themselves. The sound is no longer moving through the air, but is in fact pushing the air along with it, forming a pressurized wall of moving air.
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. Mr.
It's a ridiculously loud "sound". It's not possible as a continuous sound in air because the maximum overpressure is double atmospheric, with the troughs a vacuum, which works out at 194 decibels.
It may be possible to destroy everything with a loud enough sound. NASA estimates the mass energy of the universe at 4x1069 joules. But that number that is considerably smaller than the energy created by 1,100 decibels of sound.
But what about the loudest sound ever heard? On the morning of 27 August 1883, on the Indonesian island of Krakatoa, a volcanic eruption produced what scientists believe to be the loudest sound produced on the surface of the planet, estimated at 310 decibels (dB).
In the logarithmic scale the range of human ear's audible sounds is from 0 dB SPL (hearing threshold) to 120-140 dB SPL (pain threshold) (see table 1 below).
