what is the optimum air pressure for sound waves?

is there a graph that i can look at that ranges from 0 bar (or whatever it's measured in) to such high pressure that the air is almost a solid.

what would you measure the flow of sound waves in?

[Integral]

What do you mean by optimum? The speed of sound in air is related to temperature and density, I am sure that a bit of web searching would turn up the exact relationship so it would be trivial to create a plot. But that still does not define an "optimum" value.

flow of sound waves would be messured as the velocity of the sound.
