Digital Stethoscope Market - Industry Insights,
Trends, Outlook, and Opportunity Analysis, 2018-
2026
Digital Stethoscope is a modern technology device that transforms acoustic sound into electronic
signals, which further can be amplified for ideal listening. Electronic signals can be further
digitalized and processed to transmit them in to a laptop or personal computer. The digital
stethoscope consists of three different modules i.e. data acquisition, pre- processing, and signal
processing. Data acquisition model consists of piezoelectric sensor and microphone. This module
is responsible for buffering, amplification, and filtering of auscultated sounds whereas it is also
responsible for conversion of acoustic sound to digital signal. Pre-processing module is
responsible for filtering digital signals to remove any artifacts. Signal processing module helps
in packaging of information in high order classification and helps in clustering of the data for a
diagnostic decision. Currently available digital stethoscopes allows user to select different
frequency response modes, which allows listener to efficiently examine sounds from lungs,
heart, and other body parts. For instance, the 3M Littmann Stethoscopes Range consists of
piezoelectric sensor, which helps to reduce ambient noise using adaptive noise canceller and
allows amplification of sound up to 24 times. An advanced digital stethoscope helps to stream
heart sounds on smart phones as well.

Digital Stethoscope Market Drivers:-
Advancement in technology such as development of electronic stethoscope with Bluetooth
wireless capability is expected to be one of the major drivers of growth of digital stethoscope
market. Digital stethoscopes offer various advantages as compared to the manual stethoscopes.
One of the major advantages is that digital stethoscopes have the ability to amplify sounds, as
well as observe the received sounds on a visual display. Some Stethoscopes are also capable of
recording and replaying the captured video or audio, which helps practitioners or physicians to
maintain patients’ medical data. A new product, Steth IO has been launched by Steth IO, a
U.S.-based company, in April 2018. Steth IO is a smart phone based digital stethoscope. It can
