An acoustic isolator for attenuating through-tool acoustic signals comprises a plurality of u-shaped link members (11), where each link member has two sets of ears (17, 18) . A plurality of yoke members (12) are adapted to fit between cooperating sets of ears. A plurality of pins (13) connect the plurality of u-shaped link members (11) to the plurality of yoke members (12) for providing limited flexural compliance. The isolator may be made from metallic and /or composite materials.
