The variation in stethoscope quality implies how well it is able to pick and transmit sound while maintaining highest accuracy levels and without resulting in any false detailing for this reason, most of the health experts prefer dual – headed stethoscope with a bigger diaphragm as it is ideal to pick high-frequency vibrations.

With all due respect, why would you buy a stethoscope that doesn't transmit sound well (ie classic ii), when your objective is to learn how to hear the sounds i had a classic ii in pharmacy school (they made us buy them, so i bought the cheapest thing they would allow), and i couldn't hear squat with it. 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.
