What is a bell stethoscope for?

A bell stethoscope is a type of acoustic stethoscope that features a small, circular chest piece designed to pick up low-frequency sounds, such as heart murmurs and certain vascular sounds. It is used by healthcare professionals to listen to internal body sounds, particularly in cardiology and respiratory assessments. The bell is typically used by placing it lightly against the skin, allowing it to capture subtle sounds that may not be detected by the larger diaphragm side of the stethoscope.
