DESCRIPTION:Heart valve disease has a large and growing burden\, with a pr
 ognosis worse than many cancers. Screening with a traditional stethoscope 
 is underutilised\, often inaccurate even in skilled hands\, and requires t
 ime-consuming\, intimate examinations.\n\nIn this talk I will present a ha
 ndheld device designed to enable untrained users to record high-quality he
 art sounds without requiring patients to undress. The device\, developed a
 t the CUED Acoustics Lab\, incorporates multiple high-sensitivity sensors 
 embedded in a flexible substrate that conforms to the contours of the huma
 n body.\n\nThe use of multiple sensors allows us to address challenges fro
 m localised heart sound vibrations and noise interference. I will introduc
 e a time-frequency signal quality algorithm which we have developed to all
 ow automated selection of the best sensor in the device and rejection of r
 ecordings with insufficient diagnostic quality.\n \nA validation study con
 ducted at CUED demonstrates the device’s effectiveness across a diverse 
 range of body types\, with multiple sensors significantly increasing the l
 ikelihood of a successful recording. The device has the potential to enabl
 e accurate\, accessible and low-cost heart disease screening.
