Method and systems for non-destructive testing of a gas or liquid filled object at atmospheric pressure or high pressure. The method includes the steps of providing an acoustic pulse reflectometry (APR) system ( 200 ) having a wideband transmitter ( 210 ), a pressure sensor and short mixed wave tube ( 214 ) performing at least one calibration parameter, attaching the object to the APR system and performing a measurement to obtain at least one calibration parameter, attaching the object to the APR system and performing a measurement to obtain an object test result and processing the object test result and the at least one calibration parameter to obtain an object impulse response that reflects a status of the object.
