What is a tunable diaphragm, and where is the bell on the Master CardiologyTM stethoscope?
A tunable diaphragm gives the user the option of listening to low- and high-frequency sounds, simply by adjusting the amount of pressure applied at the site of auscultation. It is not necessary to lift the chestpiece from the patient, index the stem of the chestpiece and reposition. Rather, use light contact with the chestpiece to hear low-frequency sounds (bell mode). Use firm pressure to hear high-frequency sounds (diaphragm mode).
