Research Data

Download the full anonymized dataset for your research.

No personal data included. User IDs are hashed. Export is rate-limited.

This download provides raw, unfiltered data. By downloading you accept full responsibility for its use. The dataset relies on participant good faith. No responses are pre-screened or removed. As the number of participants grows, outliers from misunderstandings or deliberate noise naturally fade in statistical significance.

MN_rate ACR: QC flag legend

  • flagged_anchor: anchor stimulus S25 rated ≥ 3 (should be inaudible; participant likely missed the reference artifact).
  • flagged_retest: same clip presented twice (S10 vs S26) rated ≥ 2 points apart (low intra-rater consistency).
  • flagged_variance: ≥ 24 of 26 trials given the same rating (response stuck on one button).
  • flagged_fast: median reaction time < 1 s (likely clicking through without listening).

Flags are informational. Rows are not removed; decide your own QC threshold.
