Description: calculation in dB as a ratio of the measured sound pressure to a reference sound pressure which for SPL is 20 uPa; Name: acoustic pressure level
Description: Ten times the logarithm to the base 10 of the ratio of the square of the sound pressure, p, to the square of a reference value, p0, expressed in decibels; Name: Sound pressure level
Description: minimum value of ratio between the applied shear stress and rate of shear of a liquid at concept temperature it is sometimes referred to as the coefficient of dynamic viscosity, or simply viscosity. Thus dynamic viscosity is a measure of the resistance to flow or deformation of a liquid; Name: minimum dynamic viscosity at design temperature
