Which part of the stethoscope is recommended for auscultating high-pitched heart sounds?

The diaphragm of the stethoscope is specifically designed for auscultating high-pitched sounds, which include the normal heart sounds (S1 and S2) as well as any abnormal sounds that may indicate a cardiac issue, such as murmurs or friction rubs. This part of the stethoscope uses a membrane that transmits vibrations more effectively for high-frequency sounds.

In contrast, the bell of the stethoscope is more suitable for low-pitched sounds, such as certain types of heart murmurs or vascular sounds. Therefore, when assessing high-pitched heart sounds, using the diaphragm provides clearer and more accurate auscultation, enabling healthcare providers to better evaluate the patient’s cardiac condition.
