Speed of Sound vs. Altitude

Is there any formula to find out the rate of speed change
for the speed of sound as the altitude rises?
The short answer is that it does not change very much because the variables
(temperature, density, pressure) tend to cancel. There is an atmospheric
model called the "standard atmosphere 1976" which you can search and find
calculators on-line that lets you compute various atmospheric parameters as a
function of altitude. One parameter is the speed of sound.
