We are pleased to announce the 2016 PhysioNet/Computing in Cardiology Challenge: Classification of Normal/Abnormal Heart Sound Recordings. For this year's Challenge, we have released a collection of 3,125 phonocardiograms from a variety of clinical and non-clinical sources. We invite participants to develop algorithms to determine, based on a short heart sound recording, whether the patient should be referred on for an expert diagnosis.
