It’s important to research a product before you purchase it, and that’s what stethoscope reviews does for you. I have been a registered nurse for years and know that good stethoscope reviews can be a great way to decide which stethoscope to purchase. I have worked in many hospitals and I have seen so many professionals using certain stethoscopes that are inferior to a better stethoscope they could of purchased with just a little additional money. So it gave me the idea of setting up a website on stethoscope reviews.
A great deal of these stethoscope reviews are written with some input from me too because for years I have used just about every kind of stethoscope the market has to offer. This gave me an opportunity to see how different models performed and I believe gives me a good insight into stethoscope reviews. A good deal of them are great, but also a good deal aren’t.
Acoustic Stethoscope Reviews
Acoustic stethoscopes are the most typical and are what most people are familiar with. They operate by sending sound waves from the end called the bell through hollow tubes to the earpieces. Theses are the types of stethoscopes that stethoscope reviews will concern itself with for the most part. The bell end of the stethoscope usually consists of a diaphragm and a bell.
If the diaphragm is placed on the patient, body sounds vibrate the diaphragm, creating acoustic pressure waves which travel up the tubing to the listener’s ears. If the bell is placed about the patient, the vibrations from the skin directly produce acoustic pressure waves traveling up towards the listener’s ears. The bell transmits low frequency sounds, while the diaphragm transmits higher frequency sounds.
The modern stethoscope was greatly improved in the early twentieth century by two men named Rappaport and Sprague. Sound levels in the acoustic stethoscope are low to begin with. This was greatly improved in 1999 with the invention of the continuous inner lumen. The kinetic acoustic mechanism came along in 2002 and improved on this even more.
Electronic Digital Stethoscope Reviews
A stethophone, or electronic stethoscope, amplifies the sounds of the body greatly improving the usefulness of them. These figure prominently on stethoscope reviews due to their ability to enable individuals with hearing difficulties to listen and detect sounds like those with less difficulty. Several companies offer these types of electronic stethoscopes.
The digital stethoscopes turn natural sound waves into electrical signals which then are amplified and transformed back into sound waves for improved listening. Transducers in electronic stethoscopes are unlike the physics involved in acoustic stethoscopes. Advances in stethoscope technology allow the diaphragm of the electronic stethoscope to mimic the diaphragm of regular stethoscopes. The only difference is that the changes in air pressure are replaced by changes in electricity. This way the appearance of the acoustic stethoscope is preserved but you can still have the enhancements of the electronic version. We really enjoy these kinds of stethoscopes, even if they are a little more pricey.
