Abstract

An acoustic logging tool includes a support structure and a set of acoustic transducers coupled to the support structure. The set of acoustic transducers includes a first acoustic transducer and a second acoustic transducer facing the same direction. Each of the first and second acoustic transducers includes a substrate having a first end, a second end, a first side, and a second side. Each acoustic transduce further includes a first piezoelectric element coupled to the first side of the substrate and a second piezoelectric element coupled to the second side of the substrate. The first and second ends of the substrate extend beyond the first and second piezoelectric elements and are fixed to the support structure.
