Abstract/OtherAbstract:
|
A condenser microphone has been fabricated for measuring low-frequency sound pressure. The goal of this design is to keep the background noise as low as possible. The microphone features a high membrane compliance with a large backchamber volume, a prepolarized backplane, and a high impedance preamplifier located inside the backchamber. Methods for characterizing the performance of the microphone will be presented including background noise levels, which will be compared to commercially available microphones. |
