摘要:
A method for measuring the acoustic damping capacity of a specimen (114), such as a layered honeycomb structure, comprises tapping the specimen (114) with a tapping rod (102). The tapping action imparts mechanical energy to the specimen (114). The method further comprises measuring, for a time interval, energy reflected from the specimen (114) as a result of the tapping. The method further comprises creating a time-energy profile (120) based on the energy reflected from the specimen during the time interval. The method further comprises evaluating the time-energy profile (120) to determine the acoustic damping capacity of the specimen (114).
