PCB Piezotronics’ surface microphone for R&D testing features a low-profile design ideal for testing in confined spaces and windy environments. The low-profile (1/8-in height) microphone and surface mount pad reduces the impact of undesired air pressure on the microphone during the measurement process. Model 130B40 is an all-in-one, prepolarized microphone and preamplifier combination with a water- and dust-resistant cover. Maximum dynamic range allows measurements to 142 dB and a 32 dBA low noise floor. More detail at http://articles.sae.org/13242.
