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 familiar to most individuals, and operate by the transmission of sound waves from the chest piece, via air-filled hollow tubes, towards the ears. They're also the most typical. These kinds are the ones that stethoscope reviews will highlight the most. The chest piece usually consists of two sides that can be placed against the patient for listening. A diaphragm (plastic disc) or bell (hollow cup).
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
An electronic stethoscope (or stethophone) overcomes the low apparent sound levels by electronically amplifying body sounds. These figure prominently on stethoscope reviews due to their ability to enable individuals with hearing difficulties to listen and detect sounds like those with no hearing difficulty. Currently, several companies offer 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.
