Methods and apparatus for reducing vibration for an acoustic array. In an embodiment, an acoustic array includes a base structure having apertures and sensors supported by the base structure for providing an acoustic array. Vibration damping material is located in the apertures of the base structure and attachment mechanisms for secure the portions of vibration damping material to a vehicle. A mold material encapsulates the base structure, the sensors and the portions of vibration damping material. The structure and materials are selected to dampen vibration for certain frequencies.
