It truly does depend on location. On the fields you can communicate much easier than you can in the stands. The speakers are directed towards the stands. From center of the field on Archimedes to the edge of the seating there was a drastic difference in volume levels. That being said, you have to remember that sound travels in waves, and has the potential to amplify as the waves reach the higher levels due to the construction of the speakers and the stadium.
