The noise calculations were carried out at a power workstation specifically purchased for the noise calculations. The calculations took place between November 2011 and January 2012. The calculation times for all situations ranged from 8 to 12 days. The calculation time depended on the number of details in the city’s noise model and the city’s surface area.
