How can a single coefficient (calibrationFactor) characterize the difference between the acoustic environment recorded by a microphone and the real acoustic environment？
We know that different microphones have different sensitivity, but when using matlab to calibrate the microphone, only one parameter calibrationFactor is used. It is really confused that whether this parameter can reflect the difference between the sound data collected by the microphone and the real sound.
Or have we taken into account the effect of the frequency response curve when using standard 1 Hz audio?

Hi, can you give more details on what you want to measure? The calibration factor lets you match the level of another calibrated instruments such as a SPL meter. It is recommended to use a 1kHz tone, because that frequency is not affected by A- or C-weighting in the meter. This allows you to then measure SPL or other measurements with the microphone (including measurements that are not part of a typical SPL meter).
