Make sure the tubing on your stethoscope is free from any cracks or holes. You can tap on the diaphragm with the ear tips in to see if any noise is escaping from your stethoscope. Holes in the tubing will make your job much harder, especially in noisy areas.Feb 9, 2017
Dual head stethoscopes offer two heads, one on each side of the chest piece. The larger one–the diaphragm–is flatter and works better for high frequency sounds. The smaller one–the bell–looks more like an elongated cup and works best on low frequency sounds.
Check for Obstructions: If the stethoscope is commonly carried in a pocket, or hasn't routinely been cleaned, it is possible that lint or dirt could be obstructing the sound pathway. If the diaphragm is open, the bell will be closed, preventing sound from coming in through the bell, and vice versa.
Our stethoscopes can be cleaned with soap and water or with an isopropyl alcohol wipe. Another option is using a 2% bleach solution. However, the stethoscopes that contain red pigments in the tubing color (Burgundy, Pink, Plum, Peach, Raspberry, Orange, etc.) do experience slight discoloration after exposure to bleach.Nov 30, 2018
