An apparatus for detecting defects in porous elements including systems and methods for quantifying acoustic signal data. A transducer receives acoustic signals generated within a test chamber by a porous element. A signal processing device may be included for analyzing the acoustic signals received, for quantifying the acoustic signals, and for correlating the acoustic signals with physical attributes of the porous element.
