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 logarithmic decibel scale is convenient calculating sound power levels for two or more sound sources. Adding Equal Sound or Noise Power Sources. Adding Equal Sound Power Calculator. Note! Adding of two identical sources will increase the total sound power level with 3 dB (10 log(2)). Sound power and sound power level are often used to specify the noise or sound emitted from technical equipment like fans, pumps or other machines. Sound measured with microphones or sensors are sound pressure.
