The decibel (db) is a logarithmic unit that indicates the ratio of a physical quantity (usually power or intensity) relative to a specified or implied reference level
60 dB: normal conversation 90 dB: lawnmower 120 dB: rock concert 150 dB: fireworks display
In a busy urban environment, average dB levels typically range from 70 to 85 decibels.
Power is often measured in decibels (dB) because it allows for a relative comparison of power levels. dB provides a logarithmic scale that makes it easier to compare a wide range of power values. It is particularly useful for measuring power changes in systems where there is a large variance in power levels.
The dB mentioned when speaking of audio is referring to the decibel. The decibel is used to measure sound level. The purpose of mentioning it is for those who look for certain dB levels. The dB is a common measure of sound intensity that is 1 tenth of a bel on the logarithmic intensity scale.
No, when two sounds of the same level (in this case 50 dB) are played together, the resulting sound level will be 53 dB, not 100 dB. The decibel scale is logarithmic, so sound levels do not add up directly.

80 db
A normal conversation is about 70 decibels (dB). A gun firing off is about 140 dB.
Any gunshot above 140 dB will damage your hearing. An M16 is 155-163 dB An M60 is 155 dB at the shooters position.
All sound output can and is measured in dB (decibel's)
It is around 92 dB.
The units used to measure sound pressure levels are decibels (dB).
