Sound scoring
How we score sound memory
Targets are seed-generated pseudo-random browser tones inside a fixed frequency range. The same seed and difficulty reproduce the same target tones.
Not a hearing exam The round score maps ERB-rate distance onto a 0-10 assessment score with a product-calibrated curve. It is not a medical hearing score.
What the report uses
- Target frequency in Hz.
- Your submitted frequency in Hz.
- Pitch distance in cents.
- ERB-rate distance for perceptual pitch spacing.
Limits
Headphones, speaker quality, volume, browser audio behavior, background noise, and hearing range can all change performance.
