<p>2127254 9410587 PCTABS00032 A logging-tool assembly (16) for generating both flexural wavefields and compressional wavefields in the sidewall formations (30) encountered by a borehole (10). The assembly consists of a sonde (16) constructed of a plurality of segments (34, 36) that are axially rotatable with respect to each other. Each one of two of the segments includes a compartment in which is mounted a dipole bender bar transmitting transducer (40). Two additional segments (100, 102) each contain one or more binaurally sensitive receiver transducers (108, 110). Monopole transmitting (44) and receiving (110) transducers are also included in the respective appropriate segments. An acoustic isolator (29) of novel construction acoustically separates the transmitting transducers from the receiving transducers.</p>
