Following a description of microphone cartridge construction, the topics to be discussed include: electrical and mechanical microphone sensitivities, effect of the polarization voltage, electrical and mechanical stability, membrane damping, electromechanical equivalent circuit, background noise, and response to infrasound. The discussion will be interspersed with little-known factoids on microphone performance which are not found in the traditional literature.
