Percussion involves tapping the body to elicit sounds and determining whether the sounds are appropriate for a particular organ or area of the body. Hyperinflation, in turn, expands your rib cage, creating a temporary condition known as barrel chest.. The percussion sound is hyperresonant, if the sound is more hollow than normal. What causes lung resonance? The lung is filled with air (99% of lung is air), hence, percussion of it gives a resonance. Where does hyperresonance occur in the human body?
