Abstract
A microphone assembly is provided, comprising a transducer assembly including a first enclosure defining a first acoustic volume and a Micro-Electrical-Mechanical-System ('MEMS') microphone transducer disposed within the first enclosure. The microphone assembly also includes a second enclosure disposed adjacent to the first enclosure and defining a second acoustic volume in acoustic communication with the first acoustic volume, the second enclosure including an acoustic resistance, wherein the first and second acoustic volumes, in cooperation with the acoustic resistance, create an acoustic delay for producing a directional polar pattern. Circuitry comprising a shelving filter configured to correct a portion of a frequency response of the MEMS microphone transducer is also provided. In some embodiments, the circuitry is embedded within the transducer assembly or at least included within the microphone assembly. In other embodiments, the circuitry is located on a cable that is electrically connected to a connection port of the microphone assembly.
