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.

That depends how close you measure to the speaker. The closer - the louder! The distance is very important if you measure with a sound pressure level meter. In 1 meter distance the sound pressure level is arround 60 decibels SPL.
130 decibels: jackhammer, power drill, air raid
10
20 to 50 decibels (dB).

Depending on the type of aircraft and it's distance from you, usually more than 100 decibels.
20 decibels
207 decibels.
70-100 decibels
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.

130 decibels -140 decibels close up maybe louder though
•Sound can be measured in many ways such as decibels. There is a special machine which you can by that measures how many decibels something makes. A pin makes 10 decibels where as a loud persons or a stereo can make up to 80 decibels. Volume is measured in decibels. So Frequency is measured in hertz
a plane has 15000 decibels, there are lots maybe upto 2000000
