This diaphragm responds to sound waves identically to a conventional acoustic stethoscope, with changes in an electric field replacing changes in air pressure this preserves the sound of an acoustic stethoscope with the benefits of amplification. I have a littmann classic ii and i was fooling around with it for a while well, when i put it on to listen, the diaphragm side doesn't listen but the bell does how can i fix it so both.
