Frequency vs response Curve of a microphone

  1. Oct 7, 2008 #1
    Hi, was just hoping that you could clear up a mis-understanding i have:

    In a frequency response curve, the y axis is a decibel scale. Is this a comparison of the microphones response to the reference sound in relation to sound intensity.
    eg. If the microphone has a +5 db for a particular sound, does this mean that it is 5b louder than the input sound that was put into the microphone?

    Yes I believe so. That represents an amplification. Though in general the value of the frequency response lies in the relative output across your spectrum of interest, to identify non-linearity.
