How to calculate sound speed in atmosphere?

[kkk]

Hello. Just wondering how to calculate the sound speed in the atmosphere if I have temperature and pressure from the surface and all the way up to thermosphere?

hi there
welcome to PF

what reading have you done so far to find the formula to use ?

hello, and thank you for answering me.

I have read different articles, but can't find formula depending on pressure and temperature? I know how to calculate the effective sound speed, but not the the just the sound speed.

I googled ... calculating speed of sound in the atmosphere ... which is what your Q was
got lots of hits and formula

Hint ... density plays a big part

AFAIK practical limits are usually imposed - examples: max meters above and max meters below sea level.
This app will create a table for you.

directly answers your question, but you need to understand a bit about it, like a 'standard atmosphere'. This is an engineering site and has lots of good links
