A wellbore leakage detection tool and method for assembling such tool includes a longitudinal tool element, including a through bore perpendicular to a longitudinal axis of the longitudinal tool element, an acoustic insulator or damper arranged in the through bore, and an acoustic sensor assembly arranged suspended in the acoustic insulator or damper inside the through bore. The acoustic insulator or damper has an acoustic impedance different from an acoustic impedance of the tool element.
