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.
How to Measure Decibels. In common usage, decibels are usually a way to measure the volume (loudness) of a sound. Decibels are a base 10 logarithmic unit, which means that increasing a sound by 10 decibels results in a sound that is twice as loud as the base sound. In general terms, a sound's decibel value is given by the formula 10Log10(I/10-12), where I = the sound's intensity in watts/square meter.
