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 ascultating the chest walls. Over healthly lung areas, '1-2-3' is not intelligible.

Compare this sound to the recording found in the "Whispered Pectoriloquy - Abnormal" lesson.
