Removing energy from a system in the Acoustics module

I'm trying to simulate standing waves inside of a cavity network, so there are no inlets or outlets, just gas at a constant pressure and temperature as the initial conditions. I then apply power through a line source at different frequencies and look at how the standing waves form.

However, I am seeing some unphysical results. For example if my initial pressure is 100 torr, I end up with a pressure range that goes from 0 to something like 50 atmospheres. Obviously if I drop the input power down, the numbers change, but the distribution seems to remain unchanged.

So, am I missing something that would give me more realistic numbers, or do I just ignore the numbers and focus on the relative distribution? What I mean is, I have two line power sources that I have different input powers. Should I ignore the actual Watts going in, and just make sure the ratio of the powers between the two line sources are the same?
