But it’s a common miss conception since its normally colder at higher altitude! Doing the math on this, the post Robert .22 posted earlier is not wrong if he shoots at 35 degrees Celsius. The speed of sound increases with temperature.


SoS through a medium is dependent of Density. Greater the density the faster the SoS. My first degree, plus post grad qualifications, was in surveying and this is one of the basic concepts of underwater survey. In terms of air, unless I am mistaken, Air is less dense at higher altitudes therefore SoS will be slower, therefore Baz is right and you are wrong.

A cursory glance shows:
