p style="margin: 0px; text-align: justify;">When using a stethoscope with a tunable diaphragm, the healthcare professional does not have to remove the chestpiece from the patient in order to change from the bell to diaphragm mode. Also, single-sided chestpieces are shaped to provide a more comfortable grip for better feel and control. When listening to low frequency sounds with a tunable diaphragm there will be an increase in amplitude, or loudness. This is because the sound is coming through a diaphragm with a larger surface area. The sound pressure level increases with an increase in contact area on the patient.</p
