Hence, I would like to say that the Renaissance is not a revolutionary period. First of all, there is no drastic change in the politics in the Renaissance period. Renaissance inherited Feudalism from the Medieval Period.
Decibels provide a relative measure of sound intensity. The unit is based on powers of 10 to give a manageable range of numbers to encompass the wide range of the human hearing response, from the standard threshold of hearing at 1000 Hz to the threshold of pain at some ten trillion times that intensity.
So a jet engine sound can be at 12.5 m distance 130 dB. At 25 m distance 124 dB, at 50 m distance 118 dB and at 100 m distance only 114 dB. You see how important it is to tell always the distance with the measured decibel level. 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.
