Abstract 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. L'invention concerne des procédés et un appareil destinés à réduire les vibrations pour un réseau acoustique. Dans un mode de réalisation, un réseau acoustique comprend une structure de base ayant des ouvertures et des capteurs supportés par la structure de base pour fournir un réseau acoustique. Un matériau d'amortissement des vibrations est situé dans les ouvertures de la structure de base et des mécanismes de fixation destinés à fixer les portions de matériau d'amortissement des vibrations à un véhicule. Un matériau de moule encapsule la structure de base, les capteurs et les portions de matériau d'amortissement des vibrations. La structure et les matériaux sont sélectionnés pour amortir les vibrations pour certaines fréquences.
