Use of the Lx Stethoscope:
Listening to the heart with the wooden bell will be the brunt the stethoscope’s use. It takes no special hand positioning or covering of anything, as it is a closed sound chamber when listening with the wood bell. When listening with the diaphragm, cover the wood bell’s aperture fully, partially or not at all with your finger to hear higher and lower frequency ranges. Experiment with this process, as we all hear things a bit differently. We like to think of its design as the “manual transmission” of stethoscopes. You are in control of the stethoscope’s operation, it is not in control of you.
