Abstract: One example of a mount (507) for a rotorcraft (101) comprises a structural support member (512), a bracket (510), and an elastomer (508). The bracket (510) is configured to attach to a component of the rotorcraft (101). The component of the rotorcraft (101) produces vibrations at a first frequency. The structural support member (512) configured to transfer a weight of the component of a rotorcraft (101) to an airframe of the rotorcraft (101). A rotor system (103) of the rotorcraft (101) vibrates the airframe of the rotorcraft (101) at a second frequency. The elastomer (508) is located between a structural support member (512) and a bracket (510). The elastomer (508) is configured to attenuate noise caused by the vibrations at the first frequency by isolating the vibrations at the first frequency from reaching the airframe of the rotorcraft (101) while the airframe vibrates at the second frequency.
