That depends how close you measure to the mouth speaker. The closer - the louder! The distance is very important if you measure with a sound pressure level meter. A conversation in 1 meter distance may have 60 decibels.

I have a new blender at home that I think is relatively quiet for a blender. I have measured the noise from it with my iPhone as apparently only 60 decibels when standing at a distance of 1 meter away while I was blending fruits with it. Due to this, I think that there is a very large range in the noise levels of different blenders because I have heard people claim that other blenders were 90 decibels at a distance of 1 meter and I only measured my blender as being 60 decibels at that same distance. That is a difference of 30 decibels, which is a huge difference considering that the decibel scale is logarithmic. I think that the newer blenders are probably much quieter than the older blenders were.

Exactly 200 decibels will kill a human being because by 100 decibels isequivalent to a rifle 5 feet away causing a person to become partially deaf. By 150 decibels a average 160 pound person will begin to fell vibrations through there body and equivalent to 60 thousand pounds of TNT fired ten feet away from a person. Lastly by 200 decibels the bones that vibrates to form sound can not withstand the sound and blast directly into the brain causing the person to die immediately If that doesn't happen after a few seconds of such high noise frequencies the brain will become unable to withstand the intense vibrations and actually explode literally it will not cause the cranium (skull) to automatically blow to bits but the brain is ultra sensitive so it would just burst and the blood would eventually leak out the ears.
20 to 50 decibels (dB).
The sound of a normal conversation is 60dB (decibels) and a close range jet is 140dB. This makes a jet at close range over 2 times as many decibels than a close range jet. The sound of a normal conversation is 60dB (decibels) and a close range jet is 140dB. This makes a jet at close range over 2 times as many decibels than a normal conversation. The above answer is FALSE: The decibel scale is logarithmic and thus a 140 dB sound would be 10^14 above 0 decibel; the 60 dB sound would be 10^6 above 0 decibel. Thus the close range jet is around 10^(14 - 6) = 10^8, or 100,000,000 times the loudness of a normal conversation.
140 dB A normal conversation is about 60 dB (Just to let you know how loud fireworks are)
Depends on the size of the explosion.

Loudness has to do with the sensitivity of the ears of an individial. The question belongs to psycho acoustics and is not easy to answer.AnswerLoudness depends on the volume and intensity of the sound. A deaf person cannot hear and thus has insensitive ears. Her ear insensitivity has no effect on the loudness of a nearby boombox.A decibel is a logarithmic scale of loudness used to measure the strength or loudness of a signal. Your noise would need to be measured in order to determine its value in decibels.A whisper is about 20 decibels. A sound measured at around 120 decibels would border on pain. Normal conversation measures at about 60-70 decibels.
85 decibels maximum.
