“…The 5.24 dB SNR of T4 is close to the 6.9 dB SNR of a standard 3200-type of 3M Littmann stethoscope [9] although lower than the 13.58 dB SNR of a piezoelectric MEMS acoustic sensor in [8]. This indicates that the quality of 3Dprinted designs must be further improved in order to approach the SNR of a standard 3M Littmann 3200 electronic stethoscope at 23.3 dB [2] to be considered as high-quality.…”

Modern day acoustic stethoscope is a necessary equipment to aid clinical practitioners in performing diagnosis on patients. For initial assessments and long-term medical evaluations, it is beneficial for patients to be able to monitor their health status between check-ups and for doctors to be able to diagnose patients remotely. In this work, the viability of MEMS-based digital stethoscope as an alternative solution for a low-cost diagnostic equipment is proposed. The impacts of various design parameters of a 3D-printed stethoscope's chestpiece on the sound quality has been investigated. Signal-to-noise ratio (SNR) analysis of various designs achieved up to approximately 5.24 dB, indicating clear and audible heart sounds. In addition, the development and implementation of a novel web-based application with digital stethoscope is also proposed in this work for potential real-time remote auscultation.

“…Stetoskop elektronik yang berkembang di dunia sudah semakin maju dan pesat seiring dengan kemajuan digital. Penggunaan sensor magnetic juga menjadi suatu perkembangan yang dapat membantu meningkatkan kepekaan saat melakukan auskultasi bunyi jantung dan dapat dikombinasikan dengan tampilan sehingga pengguna stetoskop memperoleh sensasi audiovisal yang sempurna untuk menentukan kelainan bunyi jantung (Li et al, 2021). Beberapa metode stetoskop elektronik menggunakan ausculband.…”

“…Seiring dengan perkembangan jaman terjadi perubahan sistem dari yang manual ke eletronik dan hal itu juga terjadi pada stetoskop. Munculnya kebutuhan petugas kesehatan terhadap keakuratan pendengaran dan pemeriksaan auskultasi jantung menghasilkan inovasi baru dalam bidang stetoskop elektronik (Li et al, 2021). Hal ini dilakukan untuk menutupi kekurangan stetoskop konvensional yaitu berkurangnya kualitas ampilifkasi selama auskultasi yang disebabkan karena berbagai hal misalnya kebisingan dan juga keberhasilan mendeteksi bunyi jantung yang bergantung oleh pengalaman praktisi (Ogawa et al, 2023).…”

This study aims to see the effectiveness of using an electronic stethoscope compared to a conventional one in patients with heart valve disorders. The method used in this writing is a systematic review through several databases, namely Pubmed, ClinicalKey, Proquest, Science Direct, and Scopus. The article analysis process uses the PRISMA method. The research results show that electronic stethoscopes are more expensive because many parts and applications/software are added. Still, they are very efficient in accurately diagnosing specific heart sound abnormalities and have more advantages than conventional stethoscopes. In conclusion, electronic stethoscopes are very effective and efficient in increasing the speed and accuracy of diagnosing specific heart sound abnormalities, so they have more benefits. Keywords: Heart Valves, Electronic Stethoscope

“…Harapan perawat ini merupakan tantangan era digital yang mana melakukan perubahan dari stetoskop klasik menjadi stetoskop digital sehingga membuat stetoskop lebih fleksibel dalam penggunaanya. Hal ini sejalan dengan peneliti sebelumnya yang menyatakan bahwa stetoskop hendaknya didesan lebih nyaman dalam penggunaanya, stetoskop digital memiliki keuntungan lebih fleksibel dalam penggunaanya (Li et al 2021).…”

This study aims to analyze the problems of nurses in conducting auscultation in the intensive care unit. The research method used is descriptive qualitative research. The results of the study found three main themes found in this study, including 1) the time used for auscultation was minimal due to the large number of nurses' tasks to be completed, 2) the stethoscope used should have a clear sound when used, 3) the stethoscope should be more flexible in shape so that it is accessible to in use. In conclusion, the problem nurses face in conducting auscultation examinations on critical patients is the need for a stethoscope that has a more precise sound output and is flexible in its use. Keywords: Auscultation, Intensive Care Unit, Stethoscope
