Auscultation is typically performed directly on the skin, not over clothing, because fabric can distort or muffle sounds. However, in some urgent situations, a provider may listen over thin clothing, but this is not ideal for accuracy. For a proper auscultation: • Place the diaphragm of the stethoscope directly on the patient’s skin for high-frequency sounds (like breath and normal heart sounds). • Use the bell for low-frequency sounds (like murmurs and certain vascular bruits). If auscultation is done over clothing, the sounds may be diminished or inaccurate due to interference from fabric.0:41
