What sounds are best heard with the diaphragm of the stethoscope?
A variety of stethoscopes are available for the auscultation of heart sounds. Many stethoscopes have a separate bell and diaphragm. The bell is most effective at transmitting lower frequency sounds, while the diaphragm is most effective at transmitting higher frequency sounds.

What is a tunable diaphragm on a stethoscope?
Tunable diaphragm technology is a 3M invention that helps make auscultating a patient easier and more effective. It lets you hear different types of sounds by simply adjusting the amount of pressure you apply to the chestpiece of your 3M™ Littmann® Stethoscope.
Which side of the stethoscope do you use for blood pressure?
Do not place chestpiece underneath the cuff, as this impedes accurate measurement. Use the bell side of a combination stethoscope for clearest detection of the low pitched Korotkoff (pulse) sounds.
Where do you listen with a stethoscope?
Listen to the patient’s lungs in the upper and lower lobes, and on the front and back of the patient. As you listen place the stethoscope on the upper part of the chest, then the midclavicular line of the chest, and then the bottom part of the chest. Make sure to listen to the front and back of all of these regions.
Where do you place stethoscope for blood pressure?
Make sure your skin doesn’t pinch when the cuff inflates. Once the cuff is on, place the disk of the stethoscope facedown under the cuff, just to the inner side of your upper arm. Next, place the stethoscope earpieces in your ears, with the earpieces facing forward, pointing toward the tip of your nose.
Where is the diaphragm of the stethoscope placed?
The most important parts to know are the diaphragm, which is larger, flatter side of the chest piece, and the bell, which has the smaller, concave piece with a hole in it. Switch between the two by twisting the chest piece 180 degrees. You’ll hear a click.
