Which description best fits the chest percussion findings often seen in cystic fibrosis?

Cystic fibrosis often causes airway obstruction with mucus plugging, leading to air trapping and lung hyperinflation. When air content in the lungs is increased, percussion sounds become hyperresonant and can even be tympanic—louder and drum-like compared with normal lung. This reflects the excess air in the alveolar spaces from obstructive disease. Dull percussion would point to fluid or solid tissue in the chest, resonant would be a normal lung, and flat would suggest dense tissue or large effusion, none of which best describe the typical CF finding.
