how to link impedance and sensitivity of a PZT ?

Hello, I was wondering if somebody could help me.
I am using a PZT as a microphone and I would like to know how I can link the measure of its impedance (real and imaginary parts) to its sensitivity (response).

thank you for your help.

Re: how to link impedance and sensitivity of a PZT ?
You could try SPK electronics (see link below). They manufacture all types of piezoelectrical crystals for different uses. The link below directs you to the variables used to determine a transducers output.

Kindest Regards

oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
