Feedback:
A dull percussed sound, heard over the chest wall, is indicative of little or no air movement in that area of the lung. Lung consolidation such as in pneumonia or fluid accumulation produces the dull sound. A tympanic sound is a high-pitched sound commonly heard over the stomach or bowel. A resonant sound is noted over normal lung tissue. A hyperresonant sound is an abnormal lower pitched sound that occurs when free air exists in disease processes such as pneumothorax.
