While the Sone scale provides valuable insights into loudness perception, it is not without limitations. Individual variations in hearing and the complexity of human auditory perception mean that there can be significant variability in how different people perceive loudness.
| Aspect | Sone | dB(A) | |--------|------|-------| | Scale type | Linear (perceived) | Logarithmic (physical) | | Doubling loudness | 2× sones | ~10 dB(A) increase | | Easy to understand | Yes (twice as loud = double) | No (+3 dB is barely noticeable) | | Directly measurable? | No (needs calculation) | Yes (with standard meter) | | Frequency weighting | Built-in via equal-loudness | A-weighting (approximate) | sone scale
