Detailed Description

Complex attenuated pressure class.

The Pressure class stores a complex<double> acoustic pressure value for attenuation purposes. Pressure values are adimensional: complex pressure represented has to be considered in conjunction with transmitted pressure. Pressure also provides full arithmetic capability and a attenuation coherency check
