Most stethoscopes have a chestpiece with a bell and a diaphragm. The bell, having a smaller diameter, is used for lower pitched sounds while the diaphragm, having a larger diameter, is best for mid-range and higher pitches. Electronic stethoscopes will have a way to electronically switch between bell and diaphragm modes.
