Electronic stethoscope


The electronic or digital stethoscope is a model wich is equipped with a bluetooth connectivity, operating with a software system allowing the practitioner getting a better auscultation performance. Electronic stethoscopes are very powerful and can amplify sound while reducing ambient noise. They appeared quite recently. Being high tech gadget, they resemble only in appearance conventional stethoscopes. Thanks to their technicality, electronic stethoscopes are able to amplify sounds several times, eliminating all parasitic noise. To do this, electronic stethoscopes use special membranes with piezoelectric crystals that convert the vibrations of sound waves into an electronic signal. Then the received signal is cleaned, amplified several times and sent directly to the eartips (generaly headphones). In addition to amplifying and cleaning sound, electronic stethoscopes can record audio fragments and transmit them wirelessly to any device with connectivity. Acoustic tubing is no longer required for this type of stethoscope although it is still used in some models of electronic stethoscopes.
