Stethoscopes were originally designed to listen to a patient’s chest sounds, evaluate the state of the cardiovascular and respiratory system, and determine how well the trachea and bronchial tree are functioning as an airway. It is crucial for medical professionals to listen to the patient’s internal sounds during chest auscultation, especially during the vesicular breath sound periods.

Advancements in healthcare progress dramatically as a result of technological developments, where modern technology enables us to implement multifunctional gadgets with fast processing. Promoting the advancement of technology ensures that devices are becoming more powerful, portable, and convenient and have faster processing speeds than ever before, satisfying the needs of the healthcare industry [4]. For example, using wearable digital stethoscopes for sound recording and visualization offers real-time, wireless, and continuous auscultation via a soft wearable system that can be implemented as a quantitative diagnostic tool for various diseases [5]. The wearable technology can potentially be paired with smartphone applications for continuous auscultation monitoring [6]. These newly designed digital and electronic stethoscopes are technological advancements dedicated to healthcare professionals for use in both clinical and educational settings, thus improving on traditional auscultation techniques.
