"TIM-25-10984 - Test Subset"

"This dataset and accompanying MATLAB code present a comparative study of adaptive noise reduction techniques applied to heart sound recordings. The project focuses on improving the quality of phonocardiogram (PCG) signals acquired in realistic clinical noise environments by using dual-microphone recordings and adaptive filtering methods.The recordings consist of multiple heart sound pathologies, each combined with different real-world hospital noise sources, including corridor, reception, ambulance, and maternity ward environments. For each pathology, a clean reference recording and the original uncorrupted signal are also provided. The data are organized using a consistent naming convention that encodes the pathology type and noise condition."
