Cardiorespiratory Bioacoustics

Cardiac and respiratory sounds contain critical diagnostic information, often reflecting subtle changes in health status. Yet, the skills needed to capture, analyze, and interpret these signals are often underemphasized in traditional medical and engineering education.

Cardiorespiratory Bioacoustics: Clinical and Technical Perspectives is a practical and accessible guide that bridges the gap between clinical medicine and biomedical engineering. Aimed at students, researchers, and clinicians, the book explores the field of clinical bioacoustics through the lens of cardiorespiratory sound analysis. It offers both foundational knowledge and real-world applications, including signal acquisition, acoustic analysis, and clinical interpretation of heart and lung sounds. Readers will gain insights into the physiological origins of these sounds, their diagnostic value, and the technologies used to capture and analyze them.

What sets this book apart is its project-based approach: readers are encouraged to build and experiment with hands-on projects using Arduino microcontrollers, USB microphones, and Windows-based open-source software tools like Audacity and Spectrogram16. These include heart sound monitors, frequency-domain analyzers, and color spectrographic lung sound systems. With clear explanations, minimal technical prerequisites, and an emphasis on do-it-yourself learning, the book equips readers with both theoretical understanding and practical skills to explore and innovate in the field of clinical bioacoustics.
