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.
Adding Decibels. The logarithmic decibel scale is convenient calculating sound power levels for two or more sound sources. The decibel (dB) is a logarithmic unit used to express the ratio of two signal values - like power, sound power or pressure, voltage, intensity etc. - where one value is a reference value. more about decibel.
