The coherent acoustic pressure (and thus transmission loss and particle velocity which depend on it) is incorrectly calculated with high numbers of rays.
With increasing number of rays, the pressure at hydrophones near the source is incorrect. The higher the number of rays, the further away from the source hydrophones are affected.
The "Thresshold" for correct output seems to be around 500 rays.
