Disclosed herein are various implementations of systems and methods for improving the process and accuracy of converting acoustical signals to leak rates through a structure, such as a closed valve or coupling, using filtering techniques and modal analysis. These systems and methods may be useful for verifying the accuracy of the conventional approaches and inventive processes and systems for improving leak rate quantification using acoustic emissions. For example, a testing apparatus for simulating a leak through a structure and methods for correlating an acoustical signal with a leak rate are disclosed. The information gathered from the testing apparatus and/or correlation methods may be used in the field to determine more accurately the leak rate of a fluid or gas through the structure. |
