1/8" Measurement Microphones Datasheets

Prepolarized Pressure Microphone -- Model EM40DD
from Meggitt Sensing Systems - Measurement Group

The Endevco microphone model EM40DD is a 1/8-inch pressure microphone with a wide frequency response (see Fig.1) and a large dynamic range. Its tiny physical size reduces to a minimum the effects of diffractions and reflections created by its presence in the sound field. This allows it to be used... [See More]

Surface Microphone -- Model 130B40
from PCB Piezotronics, Inc.

The PCB ® model 130B40 is a cost effective microphone for measuring true surface pressure. Through CFD modeling software, the microphone and pad design were able to be optimized for wind induced noise applications. The flexible design allows for flush mounting or adhesive mounting on flat planar... [See More]
