BROADBAND FLEX JOINT ISOLATOR FOR ACOUSTIC TOOLS

摘要

An acoustic attenuator assembly for an acoustic tool for performing acoustic investigation of a subterranean formation is disclosed. The acoustic attenuator assembly includes a first end portion (205) and a second end portion (215) having a bore therethough to enable passage of an electrical line. The acoustic attenuator assembly further includes a fiber portion (230) disposed between the first and second end portion so that the fiber portion attenuates at least a portion of acoustic energy when the acoustic energy is received by one or both of the first (205) and second (215) end portions.
