A test cell (10) for containing equipment (12) subject to pressure testing comprises a plurality of metal plate wall panels (14) and a mesh roof panel (16) formed from mesh strands (26) of a high strength material. Each wall panel has a lapped connection (18) with an adjacent wall panel. The mesh panel (16) may be formed from a ballistic fabric, and the mesh strands (26) may be wire, rope and braid of steel, metal, plastic, natural or composite fiber, or a combination thereof. In the event of a pressure failure of the equipment (12) under test, the roof panel (16) captures fragments of the equipment while allowing the dissipation of pressure shock waves through the apertures (28) in the mesh. The lapped connections (18) between wall panels (14) result in increased friction between adjacent wall panels (14) and thus an increase in the strength of the connection when subject to pressure shock waves.

Systems and methods for determining a leak rate through an opening using acoustical sensors
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.

COMPRESSION MECHANISM FOR ACOUSTIC EMISSION SENSOR
The present disclosure relates to a method and apparatus in the field of acoustic emission sensing. The method is for optimizing the transmission of acoustic waves from a test object to an acoustical sensor, the method comprising the steps of: providing an acoustical sensor comprising a sensing interface, the sensor configured to receive sound waves emitted from a test object and generate a signal indicative of the sound waves; coupling the sensor to a surface of the test object, the test object having a first acoustical property; and adjusting a pressure incident on the sensing interface such that a second acoustical property of the sensor approaches the first acoustical properly. The apparatus includes both an acoustical sensor and an acoustical sensor housing. The acoustical sensor comprises a sensing interface configured to receive sound waves emitted from a test object, wherein the pressure incident on the sensing interface is adjusted such that a first acoustical properly of the sensing interface approaches a second acoustical properly of a test object The acoustical sensor housing assembly comprises: a first end; a second end opposite the first end; a wall extending substantially between the first and second ends, the wall and the ends defining an interior portion; and an acoustical sensor mounted adjacent the first end, the acoustical sensor comprising a sensing interface configured to receive sound waves emitted from a test object, wherein the pressure incident on the sensing interface is adjusted such that a first acoustical properly of the sensing interface approaches a second acoustical properly of a test object.
