Hello and thanks in advance for reading or contributing... In regards to another thread here, https://www.physicsforums.com/threads/sound-as-condensation-or-rarefaction-of-air.817705/ , I am convinced a compression wave would cause an oscillation as it passes your ear. This raises the question as to whether this oscillation could be audible and what factors would determine the frequency. To begin I believe that the wave should propagate through the air at the speed of sound, but I am uncertain if that is relevant. What determines the rate at which compression followed by rarefaction occurs? My intuition tells me the temperature and pressure (ambient as well as compressed) are the important factors, but I'm coming up short on techniques to model it.
