Extension of the percussion technique is implemented by applying vibro-acoustic excitation to the torso surface and using an array of measurement locations on the torso of three healthy human subjects via noncontacting scanning laser Doppler vibrometry. A 3-dimensional finite element model for simulating the vibro-acoustic response of the human upper torso is also developed. The soft tissue, ribcage, sternum and major internal organs were detailed to create an accurate geometric model. Experimental measurements partially validate the FE simulation model.
