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.

L'invention concerne un isolateur acoustique destiné à atténuer des signaux acoustiques d'instruments diagraphiques. Cet isolateur acoustique comprend une pluralité d'éléments de liaison en forme de U (11) comportant respectivement deux ensembles d'oreilles (17, 18). Une pluralité d'éléments d'accouplement (12) sont conçus pour pouvoir être intégrés entre des ensembles d'oreilles coopérants. Une pluralité de tiges (13) relient la pluralité d'éléments de liaison en forme de U (11) à la pluralité d'éléments d'accouplement (12), de façon à limiter la capacité de flexion. L'isolateur selon l'invention peut être constitué de matériaux métalliques et/ou composites.
