Whispered Pectoriloquy - Healthy

When a patient whispers '1-2-3', the voice high frequencies, or soft vowel sounds are dampened in a normal lung. Ask the patient to whisper '1-2-3' several times while auscultating the chest walls. Over healthy lung areas, '1-2-3' is not intelligible. Compare this sound to the recording found in the Whispered Pectoriloquy - Abnormal lesson.
