Stethoscopes have not evolved much since the time they were invented in 1816. The basic principle behind the contraption remains the same; auscultation. The earliest stethoscope was funnel shaped and based on the same principles as the trumpet. The stethoscope’s main function is to amplify sound inside the body. In essence, a stethoscope is comprised of a resonator which is connected to two ear pieces.
Stethoscopes are synonymous with the practice of medicine. The image of a doctor with a stethoscope coiled around his neck is universal and it is a proven fact that the presence of a stethoscope instills faith in the consulting patients.
The components of a stethoscope include a chest piece which contains two sides, a diaphragm and a bell. When the bell part is pressed against the chest of a patient, the doctor can hear the vibrations of the skin which travel as acoustic waves through the ear piece. When the same is repeated with the diaphragm, the sounds of the body vibrate it which again travels as acoustic waves through the ear pieces to the doctor’s ears.
Stethoscopes are a key part in the initial diagnosis and eventual recuperation of the patient. They are also used to listen to intestines and blood flow in the circulatory system. Most stethoscopes are acoustic and do not include electrical parts. The application of stethoscopes is not limited to medical science; they are also used to detect malfunctions in engines and other acoustic maintenance tasks like scanning vacuum chambers in labs for leaks.
What attributes do you look for when buying a stethoscope?
A modern day stethoscope should be lightweight and flexible. Medical professionals are often on duty for 12 hour shifts and carrying a bulky metal and plastic contraption around your neck each day cannot be comfortable at all. A flexible stethoscope also offers greater mobility and portability. Apart from these two obvious factors, good acoustics and ear pieces are also important. A quality stethoscope should last you for a very long while, despite regular use.
The 3M Littmann Classic III Monitoring Stethoscope 27 inch 5803 is another great product from 3M, the company which makes the best stethoscopes since its inception. The stethoscope is a tribute to and inspired by the designs made by the founder of the modern stethoscope, David Littmann who revolutionized the stethoscope industry by heavily improving acoustics and making them lighter.

The stethoscope is also fitted with 3M’s latest technological feature, tunable diaphragm feature. This feature allows physicians to hear sounds in different frequencies by simply altering the pressure on the chest piece. For low frequency sounds, the chest piece needs to be pressed lightly and for higher frequency sounds, the pressure is to be increased slightly.
The bell part of the chest piece is also more patient friendly since it does not contain a cold rim anymore. The new tunable diaphragm is also much easier to clean since it has a smooth surface. The tubing is also state-of-the-art and is much more durable and stain resistant.
The headpieces are also adjustable making the stethoscope easy to use for multiple people. The tubes can also be adjusted for comfort while the eartips are airtight and fit perfectly. The eartips also clasp firmly to the ends of the tubes, making them safer to use.
