How to use the <<tf>> function to determine the transfer function of two microphones?

Hi everyone!

Let us assume I measure the SPL of a source with 2 microphones placed at different positions from it.

How do I obtain the transfer function equation by between the 2 microphones by using the tf command in MatLab using both the Sound power levels measured by the microphones in function of frequency?

Thank you in advance!

From your description, it does not sound like tf() is what you want. Do you have the Signal Processing Toolbox? If so, have a look at tfestimate() or mscohere()

I'm assuming you have the waveform that the microphone is outputting.

Thanks for the answer!I didn't knew about tfestimate(), but it proves that it was exactly what I needed.
