As a practicing Registered Nurse I know how critical reading stethoscope reviews might be prior to deciding to purchasing one. I wanted to begin a website on stethoscope reviews because I see numerous health professionals with stethoscopes which are inferior to other ones that would of cost the identical or just a little more than the ones they wear around their necks!
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 by making use of my coworkers stethoscopes to see how they worked and if they were any good or not. A good deal of them are great, but also a good deal aren't so very good. I will initially go over the types of stethoscopes and then will go into stethoscope reviews. Please feel free to skip the initial portion and go directly for the stethoscope testimonials and other items if you would like.
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.
When the plastic diaphragm is placed on the chest wall the vibrations in the body in turn vibrate the diaphragm, the sound waves then move up the tubes to the listeners ears. Likewise, if the bell side of the end of the stethoscope is placed on the body it directly produces sound pressure that travels to the listeners ears. The bell is designed to pick up lower frequency sounds.
This 2-sided stethoscope was invented by Rappaport and Sprague in the early part in the 20th century. A dilemma with acoustic stethoscopes was that the sound level is extremely low. This difficulty was surmounted in 1999 using the invention of the stratified continuous (inner) lumen, as well as the kinetic acoustic mechanism in 2002.
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 here at stethoscope reviews really enjoy these kinds of stethoscopes, even if they are a little more pricey.
The aim of Stethoscope Reviews is to give you good information on the best stethoscopes.
