Output-Only Modal Testing of Simple Residential Structures and Acoustic Cavities Using the Response to a Simulated Sonic Boom and Ambient Excitation
Structural modal properties of single-room and two-room rectangular structures built with typical residential construction are extracted using only the vibration responses to (1) a sonic boom simulated with a linear distribution of detonating cord and (2) ambient excitation. Then, the acoustic modal properties of the cavities enclosed by the residential structures are extracted using the pressure responses to the same two types of excitation.
