What is PCB mic?

Due to novel construction the printed circuit board serves as the microphone backplate. Furthermore, other features of printed circuit board manufacturing technology are applied to minimize the number of components of the microphone.

What is a MEMS microphone?

A MEMS microphone is an electro-acoustic transducer housing a sensor (MEMS) and an application-specific integrated circuit (ASIC) in a single package. The sensor converts variable incoming sound pressure to capacitance variations that the ASIC transforms into analog or digital output.

What is an ICP microphone?

ICP® array microphones are a cost-effective alternative to measuring microphones. They are suitable for sound measurement in the field of human hearing. The array microphones of the series 130 already contain the amplifier and are characterized by an excellent phase behavior.

What is a pre polarized microphone?

GRAS examples: 40AC, 40AF, 40AG, 40BF, 40BP, 40DP and 40EN. 2) Prepolarized: Also known as electret measurement microphones. These types of microphones have a thin layer of electrically charged material on its backplate that will provide the polarization voltage needed for the plate capacitor to work.
