Overview

Medical professionals use stethoscopes to monitor your health, particularly your heart and lungs. If you head to the doctor when you’re sick, chances are the practitioner will use a stethoscope to see what’s going on internally.

But you don’t have to wait until you visit a doctor to use a stethoscope. If you have children or an elderly adult in your life, you may want to keep a stethoscope on hand for those quick checks. There are plenty of good quality stethoscopes that you can use at home without medical training.

The most popular type of stethoscope used today is acoustic, which picks up soundwaves from your body, vibrating the surface of the diaphragm on the chestpiece. That vibration makes its way to the ear tips, which brings the sound to the listener’s eardrums. When you’re looking at stethoscopes, you’ll often see acoustics mentioned as a top benefit for that very reason. Acoustics play an important role in how effective your stethoscope will be, says Dr. Anis Rehman, an endocrinologist and an assistant professor of internal medicine at SIU School of Medicine.

Another feature you’ll often see mentioned is “tunability.” This refers to the diaphragm on the chestpiece. Newer acoustic stethoscopes feature a tunable diaphragm, which puts the bell-shaped piece of metal together with the diaphragm on one side of the chestpiece. Technology is also built into the chestpiece that can record sound and provide it as a digital file. These stethoscopes also have noise-canceling features in the earpieces to make it easier to get a reading.

Of course, along with all of the technical details, you’ll want to know about the comfort of the earpieces themselves. Although you won’t be wearing it for hours on end, you’ll still need earpieces that will fit snugly enough so that you can listen without distraction. Additionally, it’s important to look for a stethoscope that is flexible enough to provide accuracy whether you’re using it on a child or adult.

Dr. Rehman also advises that you should consider how easy it will be to find replacement parts for your stethoscope, since you may eventually want to replace the eartips or the diaphragm itself.
