What is the rise time of PCB® model 377A12 microphone?

PCB® model 377A12 microphone is an under-damped system (z ≈ 0.4) and has a rise time of roughly 10 ms. This estimate needs to be verified by direct measurement on individual microphones, variability could be high because resonance frequency is not controlled in manufacturing.
