A note about the Olive Tree Lab – Barrier Calculator: a tool used for calculating the effects of infinite thin barriers from a source to a receiver. The application uses the Hadden – Pierce (Salomons) diffraction model to calculate the Insertion Loss and Barrier Excess Attenuation for a barrier. The calculations are done from 1Hz to 10,000Hz with a step of 10Hz. The results are displayed in a high resolution graph as well as in 1/1 Octave and 1/3 Octave averaged graphs. The calculation takes into consideration the Flow Resistivity of the barrier and the ground by calculating the Spherical Wave Reflection Coefficient and can therefore be used to calculate the effects of using absorptive barriers or different ground types.
