What's the optimum air pressure for sound waves?

AI Thread Summary
The optimum air pressure for sound waves is not clearly defined, as it depends on various factors like temperature and density. The speed of sound in air increases with temperature and is influenced by air pressure, but the term "optimum" lacks a specific measurement context. A graph illustrating the relationship between air pressure and sound speed could be created based on existing data. Sound wave flow is typically measured by the velocity of sound, which varies with environmental conditions. Understanding these relationships is essential for determining how sound propagates in different pressure scenarios.

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?

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.
 

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
