Comparison of Old and New

In order to understand the need to replace the acoustic stethoscope with the electronic based stethoscope, compare what each side can do and where can doctors benefit more.

Acoustic stethoscope is a two sided chest piece placed against the patient for sensing sounds, although used often times by doctors, the problem arises with the fact the it has a low quality of sounds, and cannot concentrate on the area the doctors needed to hear the status, because it also sense the noise the surrounds the area. Thus, creating a hard time for the doctors

An electronic stethoscope requires a conversion of the acoustic wave sounds to the electrical signals that can then be processed and amplified that results to an optimal listening. But unlike the acoustic stethoscopes that are all based on the same transducers, physics in the electronic stethoscopes vary.

Acoustic and Electronic differs heavily on how well they produce sounds. Better stethoscopes is better when, number it serves well and fast, and numbers two, it creates more care into producing the sounds to give optimal results.

Compare now the benefits you can have while using the common stethoscope and the electronic stethoscope. Where can you find better results?

Why Replace the Old One with an Electronic?

Electronic sounds amazing and who would love to look cool in an electronic gadget. But to doctors it’s a different kind of coolness they are looking for. Hospitals are noisy, all around, and doctors are always in a hurry to get from one check up to another to keep track on schedules that they have for the day. For example, a doctor can spend a maximum time in an appointment room for about 5-10 minutes to check the basic regulations. Heartbeat and lungs are common, but what if it was a case of a tonsillitis, then he has to check on the throat, how about fever, or an extreme case of cold? People go to checkups for different reasons. But the difference doesn’t hinder the doctor to keep track of precious time in the hospital.

An acoustic stethoscope is a classic one used for so many years by doctors all around the world. Why change it now? Littman Electronic Stethoscope is designed to amplify directly on the heartbeat and the status of the lungs. It eliminates the unnecessary noise that the doctors find it hard to differentiate from the actual noise in the body. This factor is beneficial and must be heavily considered, it makes way to a quicker and accurate diagnosis of a patient.

Price Worries are Worth It

The smallest price of a Littman Electronic Stethoscope would almost be $300, or more, while an acoustic would be at least $200. The hundred dollar comparison is a big question for many people. But it can be set aside, why? Because the benefits outweighs it. Consider it as an investment for a better doctoral service.

The fact that an electronic stethoscope can focus on the sound that you need to hear, already a big perk, not only that, some Littman Electronic Stethoscope can be has a Bluetooth that can transfer the result in any device. Not only can that it record the heartbeat of the person in just a press of a button, but also create a result quicker than manual observation

Money is always an issue of a person’s life, but often times, this issue hinders people from having devices that can help give an optimal service. Buying Littman Electronic Stethoscope is not a waste of money; rather, it is an investment that can give a batter service to patients.

A General Overview Of Headphone Stethoscopes For The Hearing Impaired

The stethoscope is an extremely vital tool for any doctor and other sorts of medical personnel that need to make a proper diagnosis. Used together with a related apparatus, a person’s blood pressure can be taken without being too invasive. With a stethoscope, a patient’s breathing can be analyzed for any issues of clogging in the lungs.

The same stethoscope that assists nurses in getting blood pressure readings can also help doctors in making a proper and more in-depth analysis of a patient’s heart, through his or her pulse. A faint beat can only mean one of two things – a faulty stethoscope, or a faulty heart, the former being easily rectified.

But wait – it can also mean that the doctor’s hearing has begun to deteriorate. Now, a faulty heart can easily be rehabilitated through proper diet and exercise. However, the same cannot be said for hearing that is going south. There are many reasons why a person’s hearing can deteriorate, and unfortunately, when it happens, it does have the tendency to hit a person’s morale.

Fortunately, there are ways that have been developed through decades of advances in technology that have brought people back to hear the same way they used to. Hearing aids have only gotten smaller and better since their introduction so many years ago. By bypassing certain areas of the ear and relaying sound to where it eventually goes, many have had their hearing restored, or at least enhanced.

This is all good news for people, but what about doctors who have contracted hearing problems? Are there ways for a doctor to use a hearing aid and a stethoscope at the same time? What are the solutions to this sort of problem?

Doctors who are hard of hearing have all sorts of problems in the workplace. In an environment where precision and consistency are always called for, they need to step up a little more in order to keep up. Most interactions may not be as intense, but details that need to be discussed need to be communicated with a little more patience around doctors with hearing problems.

Doctors who invest in hearing aids may have their hearing back, and they may be able to cope as easily as they used to in the hectic medical environment. However, this all changes when they would need to use a stethoscope. Their readings may not be accurate, which means that they would need a second or third party to use the same stethoscope.

Benefits Of Modern Stethoscopes

Today’s stethoscopes are a far cry from the traditional ones with the tuning fork design. They integrate enhancements brought about by advances in technology. What that means is that it is now possible for doctors to amplify what sounds their scopes pick up, for a more precise analysis of a patient’s condition.

That’s even more impressive is that these modern stethoscopes (you can call them ‘e-scopes’, if you prefer) eliminate the absolute need for you to adjust your ears to thick, uncomfortable binaurals – most of these stethoscopes enable sound transmission through 3.5mm jack. This means that you can connect your conventional headphones to the scope, and you can get an even better audio reading at the same time.

The benefits go even further – with the same jack it is actually possible to connect the scope straight to a hearing aid. This means that doctors with hearing problems would not need to go through the cumbersome process of taking out their hearing aids to use the stethoscope. The same jack is also compatible with any smartphone or tablet with the same outlet, meaning you are able to record sounds, or analyze them through an associated mobile application, real-time.

Types Of e-Scopes

Upon searching for electronic stethoscopes in popular sites, you will see that there are some whose design still remains faithful to the traditional look and feel, complete with the rubber tubing and the hard metal and earbuds. You could say that these are ‘bridge’ stethoscopes that help doctors transition from traditional stethoscopes to today’s more modern designs. Most of the tech is placed on the actual scope, where controls are placed to amplify sound while cancelling any ambient noise.

Headphone stethoscopes, on the other hand, are built to accommodate more observers. These are the sort of stethoscopes that doctors with hearing impediments should be looking for, as they are the devices with the 3.5mm jack, as well as additional features to accommodate common hearing aids.

Advantages/Disadvantages Of Headphone Stethoscopes

The advantages are pretty straightforward. With a headphone stethoscope you have more options for customization, for the auditory experience to be more comfortable – a plus when you’re trying to make out any issues with a patient’s heart or lungs.

  • The features of a headphone stethoscope allow you to generally enhance the entire experience to a point that your ears are completely engaged, hearing only what it should be hearing. With a headphone stethoscope you are hearing more heartbeat with less noise.
  • Due to the more flexible nature of headphones in general, they are more portable and can be adjusted to fit into smaller casings. This is a great improvement compared to the fixed metal tubes of more traditional designs.

Though headphone stethoscopes have these general pro’s, they do have their pitfalls. Their ability to utilize electricity to enhance the entire experience is both an advantage and disadvantage, in the sense that if you run out of batteries, then you would have no choice but to go back to the traditional stethoscope. This, of course, is not an option for doctors who are hearing-impaired – bringing extra batteries will always be necessary.

  • Though headphone stethoscopes are generally more portable, the fact that they integrate electronics also means that they are more delicate. You probably wouldn’t be dropping these on purpose, but if you do, they wouldn’t survive the fall as much as a traditional stethoscope would.
  • Today, you can find a good bargain for a complete set – electronic scope, headphones, and all. However, do not be surprised to see that until you see those good deals, you may need to invest a little more than you would with two or three traditional stethoscopes.

The following products are some of the best and most recent headphone stethoscopes you can find in the market.

Hearing Aid Compatible Stethoscopes

Thinklabs ONE Headphone Amplified Stethoscope

General Description:

Amazon ImageThinklabs proudly advertises this as one of their flagship modern stethoscopes, going as far as stating that ‘the icon for medicine has changed.’At first glance, the scope piece doesn’t seem like much, but don’t let this fool you – the Thinklabs ONE is claimed to be ‘The One’ for a reason.

The compact design is smooth and minimalist. It looks easy to operate, and it also looks like it can take light abuse without literally skipping a beat. There are controls to control how the sound makes it through to your ears, in order for you to make the necessary adjustments from shifting to listening to the heart to the lungs.

The entire device has at least two ports: One 3.5mm port for you to use your favorite earphones with, or to integrate with a hearing aid. The other port is a USB-style design, for you to connect it to a power outlet via a charger. This same port can be used with the Thinklink cord, included in the package. This cord is special in the sense that you could connect the ONE to a compatible mobile device, or even a laptop, for proper recording and transmission of sounds to a more reliable storage receptacle.

The ONE comes with a built-in Lithium Ion battery, so all you need to do is to make sure that the battery is fully charged before your shift, and you’re good to go.

  • Small size makes it easier to pack, store, and/or transport

Traditional rubber tubing is far sturdier and proven to last longer, while today’s audio headphones may not share the same reputation in toughness.
  • This is not a cheap device – be prepared to invest at least $500 for the minimal package including the ONE and supporting cords
  • Additional features such as presets may be intimidating to learn at first

General Information:

The folks over at Cardionics have been in the industry of producing quality stethoscopes for quite some time.

This particular review is for their second-generation headphone model, aimed at doctors and medical staff and crew that have hearing disorders. If you have a hearing aid which is an inner-ear type, this stethoscope is especially perfect for you. While this stethoscope can be used by anyone, it does have its features to ensure that even those with hearing problems can use the.

Sounds such as those from a beating heart and those taken from slow deep breathing are amplified, while any background noise is effectively eliminated.

The Cardionics’ E-Scope II is perfect to use for general usage in a clinic or hospital, yet is tough enough to keep with paramedics who have less of the luxury of time when it comes to helping their patients. The design and feel of this stethoscope can definitely leave one confident that it will stand the test of time, and then some.

Like the ThinkLink ONE, the Cardionics’ E-Scope II also has a data port for quick recording of significant sounds on a laptop or a mobile device. As mentioned earlier, this is quite a tool to be used for those instances where precise analysis and accurate diagnosis are absolutely necessary.


The Cardionics’ company certainly has one thing going for them – that is, their experience in the field of manufacturing quality stethoscopes. This is a reason why the following advantages are almost expected from this particular iteration:

Cardionics E-Scope II 7710 Belt Model Stethoscope

General Description:

Cardionics’ 7710 model can also be used for medical personnel who get assistance from inner ear hearing aids. Apparently, Cardionics has a separate headphone stethoscope model for those who use other types of hearing aids.

Thehas the same controls that the rest of Cardionics’ stethoscope lineup boasts of. They are adjustable with a simple movement of the fingertip, keeping control easy yet precise when needed. A separate control is featured dedicated to increasing or decreasing volume as necessary. Another knob is present to control frequency – this feature is particularly useful for instances where you would need to zero in on specific sounds such as those coming from the heart, or for breathing analysis.

All this control would not mean anything if the listener was also subject to hearing everything else in the background. For this reason, Cardionics was able to make changes into its design, just so that any unwanted noise is eliminated as much as possible, no matter what frequency the scope is set to at the time. If there is a need for an increase in volume, controls allow for amplification of noise to as high as 30x a conventional stethoscope.

This headphone stethoscope operates on a single independent AAA battery, as with the previously featured E-Scope II. The entire device is power-efficient, as it has an automatic shut-down feature which turns the scope off automatically after approximately two minutes of idle time. Though it does shut down after this time, the volume setting you placed it in would remain even after turning the device back on.

The entire package comes with a CD which contains instructions and the operator’s manual, for any additional troubleshooting tips and other guidelines when it comes to maintenance. Unlike the previously mentioned headphone stethoscope, the 7710 model does come with its own headphones, and even additional ear-tips for further customization and comfort, according to your ear size.

  • Visual display only adds more to the already remarkable auditory experience. With the visual display you will save time making more analysis in one go.
  • There are more features to this particular stethoscope but the entire device still looks tough enough to withstand some proper punishment, while taking barely anything away from the entire experience.

This device is also perfect for personal use especially if the family have a person with heart problem on any other illness that requires you to keep a record of your heartbeat or breathing on a daily basis. This is a good investment because you will be able to use it for a long time and you can accurately track, record and share your sound report to your doctor. It is still important that you get a doctor’s opinion on whatever findings you will get especially if you already have a history of certain illness that needs to be treated or monitored regularly.


Electronic Stethoscope Review: What’s the Best Electronic Stethoscope?

Littmann 3200 - Electronic Stethoscope Review
See it on eBay

There are many electronic stethoscopes currently available in a range of prices. As a relatively new innovation, however, it may be difficult to find enough information to make an educated choice. With that in mind, we’ve put together an electronic stethoscope review featuring some of the major players in this new and exciting market.

Electronic stethoscope overview

The basic function of an electronic stethoscope is to transform acoustic sound waves into digital electrical signals. Once converted, the sound can then be amplified and clarified for the best possible listening and assessment.

Following amplification, it also becomes necessary to reduce or filter out ambient noise. Without ambient noise reduction, distracting environmental sounds are also amplified, making listening difficult and at times even painful.

Electronic stethoscope review

We took a thorough look at the manufacturers’ specifications for four highly rated electronic scopes: the ADC Adscope 657, the Cardionics E-Scope, the Littmann 3200, and the Thinklabs ds32a.  Using the criteria of amplification, noise reduction, cost, and add-on technology, we’ve compared them head to head. Here are our results:


Amplification is measured in comparison to what the user would hear from a medium quality acoustic stethoscope. The Adscope comes in at the low end, offering 16x amplification. Littmann, with 24x amplification, is next, followed by the E-Scope at 30x. The clear winner in this category is the Thinklabs scope, with a whopping 50x amplification.

Ambient noise reduction

Neither ADC nor Cardionics provides any information regarding the noise reducing capabilities of their scopes. Thinklabs estimates the ds32a will filter out about 75% of ambient noise, while Littmann leads this category with noise reduction of about 85%.


With the least expensive electronic stethoscope coming in at a price comparable to a top-of-the-line acoustic scope, these are all a bit pricey. But there is a substantial difference between the low end ‒ the Adscope, at about $150, and the high end ‒ the E-Scope and the Littmann 3200, both $300 and up. Thinklabs comes in a close second to the Adscope, at about $200.

Add-on technology

This is where our electronic stethoscope review gets really interesting. The Adscope comes out at the bottom of this category, offering no recording, file sharing, visualization, or remote capabilities. The E-Scope provides sound recording via cable connection. It’s worth noting that the E-Scope has a special belt model that is used with headphones, making it an ideal choice for the hard of hearing.

With on-board recording capability and free visualization software via cable connection, the Thinklabs ds32a goes a step further. Mac users will also appreciate its versatile PC and Mac capabilities ‒ and for an extra $70 they offer an app that connects the stethoscope to an iPhone.

The kudos for creative and useful technology, however, go to the Littmann 3200. It features Bluetooth connectivity for sound recording, eliminating the cumbersome cables completely. Free PC compatible visualization software is included, and in addition, Littmann provides real-time teleauscultation for remote consults and examinations.

If you’re seeking the ultimate in sound transmission from a stethoscope, the electronic stethoscope is clearly the way to go. With powerfully amplified sound, ambient noise reduction, and in some cases, the ability to record and transmit digitized audio outputs, the electronic stethoscope may in fact be the wave of the future.

The Best Amplified Stethoscope for Hard of Hearing Medical Professionals

Are you wondering about the best stethoscope for hard of hearing medical professionals?

The truth is it can be extremely difficult for doctors, nurses, and medics who are hard of hearing to find a stethoscope that meets their needs. Hearing loss may increase over time; it can run the spectrum from minor to serious; and hearing aids may or may not be required. There are also many different types of hearing aids available for those who use them. All of these factors will impact how you hear the sounds of auscultation.

What all this means is that finding the best stethoscope for hard of hearing professionals is very complicated. The perfect stethoscope for one user may not be a viable option for another. For this reason, we’re basing our recommendations mostly on the advice of publications and forums devoted to the professional development of hard of hearing health care workers.

Amplified stethoscopes: best bets for professionals not using hearing aids

If your hearing loss is mild and you don’t use a hearing aid, a high-quality amplified stethoscope is your best bet. Additionally, if you use a hearing aid but don’t mind removing it to use a stethoscope, you may also want to consider an amplified stethoscope.

The stethoscopes listed below are designed for use without a hearing aid. It is possible to get specialty earpieces which allow use with a hearing aid, but most users describe these as extremely painful and nearly impossible to use. It’s also possible to have your audiologist adapt your hearing aid for stethoscope use. This often results in heavy feedback, though, and usually turns out to be an incomplete solution.

Based on significant research, we can offer the following choices for medical professionals who can use a stethoscope without a hearing aid:

Both the Welch-Allyn Master Elite and the Littmann Electronic 3200 get special notice for their cutting edge technology. Either one can be used to record and analyze sound with the help of a computer and special software.

The Cardiology III from 3M Littmann takes the #1 spot due to its sound quality and comfort on the ear canal. Whether taking a blood pressure reading or listening to a baby heartbeat the sounds comes through clearly and reliably. At the upper end of the price range, the Cardiology III is generally going to be purchased by medical doctors.

For nurses, EMTs, and other medics a more cost-effective option is the Welch-Allyn Master Elite.

Both of these models feature a tunable diaphragm to maximize sound quality.

Specialty scopes: the best stethoscope for hard of hearing professionals using hearing aids and cochlear implants

The selection of stethoscopes that can be used with a hearing aid is more limited ‒ and if this is your only option, be prepared to make a sizable investment. These stethoscopes are designed to use with accessories that adapt them to work with your hearing aid, generally via Direct Audio Input and/or headphones because they are electronic stethoscopes. They include the following:

The newest addition to this list is the Audiologists’s Choice Stethoscope, which entered the marketplace in 2012. It deserves special mention because it is the first ever Bluetooth-enabled stethoscope. If you’re currently using this stethoscope, we would love to hear from you! Eko has also entered the bluetooth market with its Eko Digital Stethoscope, however user reports indicate it can be difficult to tune the diaphragm to focus on auscultation rather than picking up all background noise in the room.

Which is best for you will depend on what kind of hearing instrument you are using. With hearing aids or cochlear implants, you need to make sure that the stethoscope you purchase will fit comfortable in your ear canal. A device that is painful to use will not be used for very long.

Look for options to use over-the-ear headphones for maximum comfort and ease of use.

The Cardionics E-Scope receives the best and most frequent reviews of these three stethoscopes, and it’s our choice as the best stethoscope for hard of hearing medical professionals.

Super-Specialty Scopes: the best stethoscope for deaf medical professionals

For those medical professionals who are completely deaf, it is going to be near impossible to find a stethoscope that will work. Essentially you are limited to digital oscilloscopes, which fortunately are becoming more widely available as technology improves.

One option includes the Eko Digital Stethoscope which has a bluetooth connection to a smartphone app.
