PointSound triggers play an instance of the soundresource they are given when a player is within an appropriate radius, the attenuation of the sound can be modified. PointSoundDummy triggers inherit all properties of the provided PointSound trigger, but do not act as a unique instance of the sound. They serve to extend the range of the PointSound trigger across multiple points. This can be helpful for preventing multiple instances of the same sound from playing together; also it is simply easier maintenance.
