1. A system, comprising:
a transducer assembly, the transducer assembly comprising:
a housing comprising a transducer housing portion having a front face and a ribbed housing portion comprising a plurality of attenuating ribs, wherein the plurality of attenuating ribs comprises at least two attenuating ribs differing in both diameter and width; and
a transducer positioned in the housing and configured to direct an emitted acoustic signal through the front face of the housing and to receive a received acoustic signal through the front face of the housing, wherein the transducer housing portion completely surrounds the transducer,
wherein a first attenuating rib of the plurality of attenuating ribs is closest to the transducer housing portion, and the first attenuating rib has a first diameter not larger than a housing diameter of the transducer housing portion.
