Pre-trained acoustic foundation models estimate heart rate from phonocardiogram recordings with accuracy similar to a conventional feature-based method.
The thick purple line represents the average MAE ( M AEj) across the 6 splits, with the light purple shaded area indi- cating the standard deviation (σ M AEj )
