hello I want to find the frequency response of a microphone. I give the input signal to my speaker and it produces a specific SPL with specific frequency. on the other side, I read the microphone output voltage. but I wonder which value of SPL is required to find the frequency response of microphone? should I fix the SPL and just change the frequency and read the microphone output? if so, which SPL value I must choose? should I fix the SPL to 94 dB SPL?
you can assume that I have a really precise reference microphone and I can find out the SPL of speaker by means of this reference microphone. I also don't really care about direction and distance because I use the reference mic so the only thing that matters to me is SPL. also assume that I afford very precise speaker too and don't care about it's response. I appreciate your help
