What is the difference between the bell and the diaphragm of a stethoscope?
The stethoscope has two different heads to receive sound, the bell and the diaphragm. The bell is used to detect low-frequency sounds and the diaphragm to detect high-frequency sounds.
What part is the bell of a stethoscope?
Bell. The bell is another circular end of the chestpiece. On two-sided chestpieces, the bell is the smaller end. Due to its smaller diameter, it has a more restricted range that focuses on lower frequency sounds than the diaphragm.

What heart sounds can be heard with a stethoscope?
Normally, two distinct sounds are heard through the stethoscope: a low, slightly prolonged lub (first sound) occurring at the beginning of ventricular contraction, or systole, and produced by closure of the mitral and tricuspid valves, and a sharper, higher-pitched dup (second sound), caused by closure of aortic …
