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.
The Decibel Scale. An explanation of the decibel scale and related units for measuring sound and loudness. The ear has the remarkable ability to handle an enormous range of sound levels. In order to express levels of sound meaningfully in numbers that are more manageable, a logarithmic scale is used, rather than a linear one. This scale is the decibel scale.
