Going back to the schematic of the microphone module, we see that the original signal is amplified by about 100 times and so the actual sensitivity of the microphone is calculated to be: Microphone sensitivity is typically measured with a 1kHz sine wave at a 94dB sound pressure level (SPL), or with 1Pa pressure.

The sound pressure level (SPL) is a logarithmic measure of the ratio of a sound pressure over a reference sound pressure (corresponding to the hearing threshold of a young, healthy ear), quoted as a dB. If these two pressures are the same, we have an SPL of 0 dB. A sound pressure level is what we can physically measure using a sound …
