Today had a lot more to offer than yesterday because I actually did important work for the company. Basically on I-95, there needs to be noise barriers because the road creates sound > 67 dBs on average. I went onto Google Earth and used the street viewer for literally miles of road to check for speed limit signs. I marked a pin and labeled their coordinates and location. That speed limit + 5 mph was added into the simulation (because nobody obeys the actual speed limit) so that TNM can calculate the average level of sound at each house for each build design.
