A digital stethoscope with active noise suppression and automatic detection of abnormalities in lung sounds

Auscultation, the action of listening to sounds from the body, typically with a stethoscope, as a part of medical diagnosis remains one of the most common, and cost-effective diagnostic practices but requires a high level of expertise. Although widely practiced, it is undermined by subjectivity in interpretation, limiting the ability to accurately interpret sounds objectively and repeatedly. Frequently, high environmental noise levels render conventional stethoscopes useless. It is also true that substantial experience is required in order to properly diagnose lung abnormalities such as pneumonia and Covid-19. Here we present a digital stethoscope with active noise suppression and an artificial intelligence algorithm (AI) that identifies lung abnormalities with accuracy comparable to trained medical personnel. This new line of respiratory diagnostic tools is appropriate for community health workers in under-resourced regions, for chronic respiratory patients in their home, and for medical professionals in noisy clinics, who wish to improve their ability to hear and interpret lung sounds. This conversation will also explore the opportunities and obstacles associated with bringing a product from the lab to the marketplace.

James E. West

Ellington S. West

James E. West is currently Professor at Johns Hopkins University, Department of Electrical and Computer Engineering and the Department of Mechanical Engineering. His pioneering research on charge storage and transport in polymers (the electrical analogy of a permanent magnet) led to the development of electret transducers for sound recording and voice communication. West was inducted into The National Inventors Hall of Fame in 1999 for the invention of the electret microphone. He is a member of the National Academy of Engineering; a Fellow, and past President, of the Acoustical Society of America, and a Fellow of the IEEE. West is the recipient of the Acoustical Society of America's Silver and Gold Medals in Engineering Acoustics, the National Medal of Technology, and the Benjamin Franklin Medal in Engineering

Ellington West is the Co-Founder and CEO of Sonavi Labs. She brings over 10 years of experience in healthcare business development, market research and leadership to Sonavi Labs and is overseeing the development of the company's inaugural product line. Prior to founding Sonavi Labs, Ellington served as the Mid- Atlantic Director of Sales for a national healthcare organization, driving 250M in revenue annually.
