With consolidation in the lung tissue, the breath sounds are louder and easier to hear, whereas healthy lung tissue produces softer sounds. This is because:
a. consolidation echoes in the chest.
b. consolidation is a poor conductor of sound.
c. air-filled lung sounds are from smaller spaces.
d. air-filled lung tissue is an insulator of sound.
D
Air is a poor conductor of sound. Denser consolidation promotes louder sounds and is a better conductor of sound. Consolidation is a better conductor of sound than air. Breath sounds are eas-ier to hear when the lungs are consolidated; the mass surrounding the tube of the respiratory tree promotes sound transmission better than air-filled alveoli.
