Voice high frequencies are more readily transmitted to the chest wall in abnormal lungs as compared to normal lungs.

Ask the patient to whisper "1-2-3" several times while auscultating across the chest walls. The lung area is abnormal if the "1-2-3" sound is understood. This is the abnormal '1-2-3'.

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

After reviewing the sound, use the waveform and anatomy tabs for more information about this sound.
