Lesson

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

Ask the patient to say "99" several times while auscultating the chest walls. Over consolidated areas "99" is understandable. This is because acoustic filtering is reduced in consolidated lung tissue, which allows better sound transmission.

Compare this breath sound to the recording in the "Bronchophony - Healthy" lesson.

As you listen to this sound, observe the waveform. This is a graph of sound amplitude (loudness) on the vertical axis vs time on the horizontal axis.
