A system and method for enhanced acoustic sensing of signals in a pipe using a fiber optic sensing cable that can be interrogated by distributed acoustic sensing (DAS) systems wherein a crescent shaped metallic device is used for attaching to the exterior of the pipe, the crescent shaped metallic device having the one or more fiber optic sensing cables embedded within an upper part of the crescent shaped device, and the crescent shaped metallic device may have one or more cavities or channels that may be empty or partially or completely filled with acoustic filters.
