Acoustic Heart Sound Signals For ECG Waveform Reconstruction

13 human volunteers provided synchronous acoustic heart sound and reference ECG signals sampled at 4 kHz. Paul Schmalenberg created this dataset for a proof-of-concept study on non-invasive cardiac monitoring using a custom Helmholtz resonator cavity. Data was last updated in March 2026.

Use Cases

• Train Conv-TasNet models to reconstruct ECG PQRST morphology from acoustic pressure signals.
• Develop models for estimating heart rate variability from non-contact acoustic heart sounds.
• Benchmark signal separation algorithms on paired acoustic and ECG time-series data.
• Validate inter-beat interval detection algorithms using the reference Lead II ECG signal.

Strengths

• 13 participant records with synchronous acoustic and ECG ground truth
• 4 kHz sampling rate captures detailed waveform morphology
• Data collected through layers of clothing for real-world relevance

Limitations

• Small participant pool of 13 limits generalizability
• Data collected in a quiet lab setting may not reflect noisy environments
• Unknown row count and specific column structure
