Frequency Discrimination Thresholds
This dataset aggregates performance metrics for the Tone Deaf Test (Amusia). Use this table to understand the distribution of scores across different percentiles or demographics.
| Sensitivity Level | JND (Hz at 440Hz) | Musical Ability |
|---|---|---|
| Elite | < 2 Hz | Professional Musician |
| High | 2 - 5 Hz | Trained Ear |
| Average | 6 - 15 Hz | Normal |
| Low | 16 - 25 Hz | Untrained |
| Deficient | > 26 Hz | Possible Amusia |
Statistical Significance
The benchmarks provided here represent averages gathered from standardized digital environments. Factors such as device input latency (for reaction tests) or audio hardware quality (for hearing tests) play a significant role in individual scores. A variance of ±10-15% is expected across different hardware configurations.
Improving Your Score
Most cognitive and sensory skills measured here demonstrate neuroplasticity. Consistent training with the Tone Deaf Test (Amusia) can lead to measurable improvements. For example, reaction times can often be reduced by 10-20ms with adequate sleep and regular reflex training.
