The 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.
