It depends on a number of factors such as the original amplitude and frequency content of the sound,
When trying to measure things like this, RT60 is an important term to keep in mind.

How long does a sound travel for, before it's dispersed into nothingness?

and rt60 is in reference to the environment, how many walls or objects are defeating the sound wave? I am taking a position that you are in the dessert, with nothing around, therefore nothing to reverberate off of and therefore rt60 is irrelevant. If you want to calculate rt60 into the equation, there is no answer because rt60 is a variable sausage dependent on room size and contents. but 20hz unabstructed @70 degress F will travel 56.5 feet p/cycle.
