Back in 1816, Rene Laennec who was a French physician, came up with the first ever stethoscope. He did that using a long, rolled paper tube to funnel the sound evenly. Although it was simple, yet it was effective. Almost twenty-five years later, George P. Cammann of New York, invented the first stethoscope with an earpiece for each ear respectively. Little did he know that this particular model would be used for more than 100 years with very few alterations.
It was not until the 60s that Dr. David Littmann, a Harvard Medical School and professor, a distinguished cardiologist having recognized international authority on Electrocardiography, patented a state-of-the-art new stethoscope with a vastly improved acoustical performance. With his help he managed to transform a simple listening device into a powerful as well as a meaningful diagnostic tool.
What makes Littmann Master Cardiology Stethoscope so special?
To this day, thanks to numerous inventions such as the Ambient Noise Reduction and of course, the Bluetooth technology, the 3M Littmann Stethoscope is a strong standard by the basis of which all other stethoscopes are measured and judged. Throughout the entire world, the Littmann brand name ensures you superior acoustics, inventive design and exceptionally great performance.
3M Littmann Stethoscopes are well known worldwide for incomparable quality, performance and innovative design. These are by far the best stethoscopes for nurses as per their preference as well and the stethoscope’s own performance. One of our most distinguished inventions includes the Tunable Technology that we have added to the stethoscope diaphragm. This tunable (also known as dual-frequency) stethoscope diaphragms combines the bell (for low frequencies) and the diaphragm (for high frequencies) into a one whole side of the chest-piece. You can easily switch between bell and diaphragm modes by just varying the pressure exerted to the patient. Hence, there is no need to actually turn the chest piece over. With 3M Littmann stethoscopes, you can now experience high quality stethoscope noise reduction from.

The Ambient Noise Reduction Technology will help you with detecting critical sounds more easily. These sounds include:
- S3 gallops,
- Aortic regurgitation murmurs,
- Unusual abnormal lung sounds,
- All those sounds you need to hear – even in work environments that are fairly noisy.
You can also increase the sound level up to 24 times, for sounds that are too faint.
Taking Care of the Stethoscope: Basic Cleaning Tips
Below listed are the top points you need to consider while cleaning the Littmann Stethoscope:
- In case your stethoscope needs to be disinfected you need to wipe it with a 70% isopropyl alcohol solution
- Never immerse your stethoscope in any liquid or expose it to any sort of sterilization
- Keep the stethoscope away from extreme heat, cold, solvents and oils
- The ear tips can be removed from the ear-tubes for easy cleaning as well
How to Use the Littmann Master Cardiology Stethoscope
Its are best known for first-class sound quality and comfort.
But there are some things you can do to make sure it gives you a good performance and wear ability.
- Align the Headset
Before you place the ear tips in your ears, hold the headset in ahead of you with the ear-tubes pointing away. When the ear tips are nicely adjusted in your ears, they should point forward. If it still doesn’t give you comfort or the acoustic performance is somehow lacking, hold each of the ear tubes and adjust the headset for a nice fit.
If you wear the headset the wrong way, it can result in a poor acoustical seal and also cause complete sound blockage in some cases.
- Focus on Tubes
If you fancy wearing your stethoscope around your neck, wear it over a collar so that you keep the tubing bendable.
- Choose the Right Ear tip Size
To achieve the best acoustic performance, it is crucial to use the ear-tip size that nicely fits your ear. This is true when using the soft-sealing ear tips, all of which are available in small and large.
- Remove Possible Hurdles
While carrying your stethoscope in a pocket, if you don’t clean it often, lint or dirt may clog the sound pathway. To prevent this, you need to give your stethoscope routine cleaning and care.
- Observing the Seal
Stethoscopes depend on an airtight seal in order to transfer body sounds from the patient to the doctor’s ears. Any loose tubing, or cracked tubing can prevent an airtight seal.
- Opening the Bell
When you use a double-sided stethoscope, you need to index the bell or the diaphragm by rotating the chest piece. If this diaphragm is open, the bell will be closed and this will prevent any sort of sound from coming in through the bell, and Vic
