Heart Rate Response Profiles for 16 Auditory Test Signals

Profiles contain physiological orienting response data for 16 test sounds, measured by heart rate change in 22 participants. The dataset was created by Mako Katagiri and published on figshare in April 2026. It is a small dataset of 5.5 KB, stored in an XLS file.

Use Cases

• Identify alarm signals by analyzing positive orienting response (OR) values, such as for the C6 + G#6 complex sound.
• Select calming pre-signals by examining negative OR values, like those recorded for the C3 + E3 musical sound.
• Assess the reproducibility of physiological responses by comparing OR values across the 11 sounds with reproducible results.
• Correlate sound frequency (130.8 Hz to 1661.4 Hz) and composition (musical vs. complex) with the normalized RRI difference metric.
• Validate the experimental protocol simulating daily life by examining heart rate (HR) changes before and after sound presentation across multiple participant sessions.

Strengths

• Data includes 16 distinct test sounds covering a frequency range from 130.8 Hz to 1661.4 Hz.
• Results are based on experiments with 22 healthy young male participants.
• The orienting response metric uses a specific, normalized calculation (RRI difference / standard deviation of RRI).
• Findings show reproducible OR values for 11 out of the 16 test sounds.

Limitations

• The dataset is very small at 5.5 KB, indicating limited scope and likely a small number of data rows.
• The participant pool is limited to 22 healthy young males, which restricts generalizability.
• Temporal coverage is limited to a specific experimental period with a washout interval, not longitudinal.
