Lesson

For heart sounds listen to the synthetic sound while reviewing this lesson.

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.

The waveform(s) seen above are a chart of sound amplitude (loudness) on the vertical axis against time on the horizontal axis.
