How reliable is the official graph on the spec sheet?
Our graph is considered “typical” as most published graphs should be. How reliable depends on your expectations, for most applications +/-2 or 3dB is more than adequate, but some expect +/- 1dB or 0.5dB, this becomes more complex and requires microphones that can be calibrated by a certified lab on a regular basis. If you a customer requires the exact response of the microphone then they should request a sweep and maybe sensitivity for the specific microphone. Again for this you should routinely send the microphone in to a lab (they are available around the world) and have them do this so you know that the data is correct and up to date. Keep in mind that with a good reliable graph, almost any good microphone can be used for general reference purpose as long as you have the graph data, the idea of these relatively flat microphones is that for general applications ( such as room analysis or looking at a speaker response etc.) that you know that the microphone is relatively flat from app
