We have ushered in several inventions into the market due to technological advancements in this era. Littmann stethoscopes are essential medical instruments used to listen to breathing actions and other sounds in internal organs. However, adjusting these devices is essential for better performance.

The adjustment process might turn complicated if you aren’t informed how to do it. Our article is of great importance to people who need to understand how to go about adjusting Littmann Stethoscopes. Let’s continue reading to gain insight into this topic.

How to Adjust a Littmann Stethoscope?

After purchasing a Littmann stethoscope, you will think about how to utilize it maximumly. To gain an understanding of it, there is a need to understand all components that make the Littmann Stethoscope. Herein we go on with a brief discussion about the Littmann components.


The function of a diaphragm is to capture low-pitched actions in the internal organs of a person. It’s constructed flat and circular to lean easily on an individual’s body.


The bell of a Littmann stethoscope is located at the back of the diaphragm. It’s cup-shaped and its role entails capturing high-pitched actions in internal organs.


Here is another important component of a Littmann Stethoscope. Their function is to transmit internal organ actions through the ear tubes to the earpiece.

Aural Tubes

These are short tubes located between the acoustic tubing and the earpieces. They are made of metal and their work generally entails the transmission of low-frequency actions.


Lastly, we have the earpieces as one of the basic components of the Littmann Stethoscope. Their role is to block other forms of external sounds that might affect the resultant actions in the organs.

Now, the above components make up the Littmann stethoscope. After understanding them, you can’t get into the process involved in adjusting the device. Below is a manual presented step by step to carry out this project.

Aligning the Stethoscope Headset

This is where you will start from when adjusting your Littmann stethoscope. Before you think about inserting into your ears the ear tips, ensure you align them properly. The ear tips should point forward as well as away from you. In such a position, they remain aligned with the ear canals to give you optimum comfort. Moreover, proper alignment of headsets ensures you get maximum transmission of sound.

When using the headset, you should use the ear tubes in separate hands. Follow to pull them open and insert the ear tips to listen to actions in the internal organs. In case you haven’t gotten the comfort, you need, then look for ways to adjust their tension. Increasing the head tension is simple; you will do this by pulling the earpieces together. If you intend to decrease tension, then you should pull them apart.

Consequently, you need to wear the headsets properly if you need them to give you the best results. An example of improper wearing involves when the ear tips point backward. Improper wearing blocks sound complete or poor acoustic sealing.
According to emergencyround you can find the best solution.

Employ the Right Size Ear Tip

This is another important thing if you need to get maximum acoustic performance from these devices. Therefore, professional advice medics employ ear tips that fit properly in their ears. Such a thing is of importance especially if your ear tips have a soft seal. When purchasing ear tips, you will find them in large and small sizes. Therefore, get what seems to fit you excellently.

Ensure you Rotate Towards the Correct Side

We have the single- and double-sided Stethoscopes around. If you have a double-sided model, there is a need to index the side you intend to use. Rotating the chest piece sets you to use either the diaphragm or a bell. Whenever one of the components opens, the other one automatically closes. This prevents actions that might come through the other part.

Removing All Potential Obstructions

At times you might carry your Littmann stethoscope in the pocket or bag. Obviously, they will accumulate some dirt and lint. Accumulated dirt in the system might create an obstruction on the sound pathway. In such cases, there is a need to provide these machines routine cleaning. There are other models where you can cover the bells using removable diaphragms. Spare your device from all possible dirt particles if you need the proper transmission of sound from them.

Inspect the Seal

Without a seal, there will be no transmission of sound to the physician’s ears. However, you just don’t look at any seal you find in the market, Littmann Stethoscopes rely only on airtight seals. Moreover, you should always look at any issues with other components of the device. Issues can be for instance loose components in the device chest piece, and improperly seated ear tips. Other issues that might hinder performance are cracked or lose tubing. Inspect these issues before employing the device to get the best results from them.

When using a Littman Stethoscope, it’s important you stay careful about the sounds you produce or from another individual. Whenever you get alarmed by other sounds, try rotating over the bell and diaphragm. Compare transmitted sound to the bell and diaphragm. A healthy sound should not crack or wheeze at all.

Apart from listening to the sound of the heart, you can use this device if you note changes in breathing. Just place your stethoscope on the chest and listen to your breathing pattern. We adjust the Littmann stethoscopes to allow them to optimize wearability as well as their general performance.


Littmann Stethoscopes serve an important role in the medical industry in different ways. They help to listen to the sound actions in people’s hearts. Moreover, they are good at listening to the individual’s breathing patterns. The adjustment ideas above are meant to set the devices properly for optimum performance. Incorporate them and trust me, your Littmann Stethoscope will offer you the best results ever.
