sensitivity of the microphone is one of the most important factors,
which affects the receiving result. The higher the sensitivity is,
the higher the SPL can be received.
Different from the production process of other products, the microphone
is selected and sorted by its sensitivity after producing. We cannot
get 1000pcs of what we need in sensitivity from just inputting 1000pcs
of microphones’ material on the production line. Therefore, in order
to avoid discontinuing the production, we had better choose the
spec. usually with the sensitivity of -40 to -44, which is popular
and easily produced.
About the volume, we can still improve it by modifying the circuit,
such as the impedance, the voltage, and the amplification factor.
We suggest that do not choose a special spec. with very high or
low sensitivity at first, or the problem of lead time and lacking
of material might happen.
