Abstract
A stethoscope with a chestpiece which has two microphones oriented at a very obtuse angle to each other. The user of the stethoscope can switch from one microphone to the other with just a slight tilt of the hand. In preferred embodiments, no special action needs to be taken to activate the selected microphone as merely touching it to the patient's body selects it for activation.
