How does humidity affect the speed of sound in gas medium ?

The speed of sound is affected by temperature and humidity.

Explanation:

The speed of sound is affected by temperature and humidity. Because it is less dense, sound passes through hot air faster than it passes through cold air. Precisely,The speed of sound in a medium is inversely proportional to the square root of its density and when moisture is removed from air, its density increases.

Since density has matter of some sort, sound speeds will vary. Hope this helps.
