Are digital and electronic stethoscopes the same?

The advanced form of electronic stethoscopes or one of the branches of its tree is a digital stethoscope. But the phenomena on which both works are mostly the same. Electronic stethoscopes overcome the challenge of low sound receiving by amplifying the sounds.

Digitized stethoscopes are used to convert audio signals to a digital one that can be shared in real time. Electronic stethoscope works in collaboration with the digital diagnostic tool detecting sound through electronic sensor and converting the energy by amplifying or filter it.

Its carefully designed circuitry is able to convert acoustic signals into electronic signals. This process is ideal for accurate listening at different frequency levels allows the energy to be boosted.

This energy can also be digitalized, encoded or decoded at the same time where the noise can be reduced and eliminated.

Certain components like sound transducers, speakers, headsets, eartips or diaphragms etc are responsible in this process of sound catching and transmitting. Placing the microphone upon the chest piece is one of the easiest way to detect sound.

A thick rubber made diaphragm or piezoelectric crystal structure with a metal shaft at its head is also included in the making of electric stethoscopes.

Being able to respond to the sound waves with the help of an electromagnetic diaphragm that involves a conductive inner surface is able to preserve it identically.

With the help of continuous practice, one needs to get familiar with electronic stethoscope or even digital one. They both have several designs and a bit different algorithms or features which are able to pick up sound, capture, record and transit it to the users.

The sounds which are obtained through these types of stethoscopes are to be considered one of the best sounds in the market.

Wireless transmission and recoding of clips into digital data are the positive steps one can take with these tools.

Keeping in mind both sides of the instrument, its usage, and cons, you are able to get past the confusion of choosing these stethoscopes as your personal favorite or not.

On what principles a digital stethoscope work?

The main purpose of a stethoscope, no matter its type, is to listen to the sounds and vibrations of human body. The process of auscultation can be as simple or complicated depending upon the circumstances and environment where it is carried out.

Leading to the right diagnosis, the correct tool is needed to be used to fulfill the purpose. An acoustic stethoscope may fill the space but sometimes one needs to adjust the sound level or frequency. With the added features a digital or electronic stethoscope is the key.

This type of tool serves you with decent capabilities including sound recording, Bluetooth connectivity, tube free check-up and connecting it to other devices as a display monitor.An improved performance does not hurt anyone and is preferred by many practitioners.

The following principles make a digital stethoscope work wonders in its field:

  • Sound transducer
  • Transmission of data
  • Display diaphragm
  • Power usage

Sound transducer:

The sound a stethoscope transmits is one of the basic elements of a digital stethoscope including the signals and speakers. Sound transducer has a fixed audio signal path where it converts sound into analog voltage.

Being one of the critical processes in the whole anatomy of the tool, this principle enables the accurate diagnostic.

The raw analog voltage is conditioned first and then turned into digital signal which is also known as analog digital converter (ADC). For the stethoscopes which contain active noise cancellation technology, they are equipped with secondary transducer.

A microphone in the absence of secondary transducer is the key to catch the noise and eliminate it when necessary. For this procedure to work in its best form, it is made with dual analog digital converters.

The headphones or amplifying speakers let the signals condition first before putting it out. A single speaker can be found below the tubing and the sound that is amplified from it travels all the way up to the users’ ears.

Transmission of data:

After the captured signals are converted into digital ones they are ready to be send through an audio jack. It can be played onto a computer or another device with the help of digital stethoscope.

This sound which is captured into the body can also be changed with its frequency. A real time clock is added to let the user facilitate with recording the readings and view it in real time.

The sound is also easy to manipulate and adjust according to the users’ needs. Transference of such audio data into the computer or another diagnosis machine is possible with this type of stethoscope.

Display diaphragm:

There is a small display usually upon the diaphragm and some have buttons on it with LEDs to indicate the readings. Backlighting which is often low represents the process and its readings on the display. They are often controlled by two WLEDs or an electroluminescent panel.

Power usage:

Running on batteries, mostly stethoscopes of these types can be used with AAA 1.5V cells. To boost up its performance or different design may require 3.0V to 5.0V depending on the circuitry.

A battery indicator put onto the stethoscope is a good upgrade so that the patient’s checkup is not disturbed or stopped to replace the batteries.
