Functional relationship between pressure and position(1d).

  1. Oct 1, 2014 #1
    Hello there, so today I started doing my research on oscillations in a course on advanced mechanics. The experiment was to mathematically model the speed of sound in air and experimentally prove the usability of the model. To keep it simple and pose my question as directly as possible, my professor told me to use the driving sound wave from the speaker in a open cylindrical tube. Further, the maxima of the voltage as read by the microphone(displayed by the oscilloscope) was to be considered as the peak(amplitude) of the pressure.
    What I am trying to establish is the functional relationship between pressure and position. I have a graph of voltage against position(attached), but I do not know what to fit the data points with.
    All your suggestions and help is hereby gratefully appreciated. Thank you in advance.

    Thanks for the post! Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
