Sone118 [verified]

This linear scale makes sones incredibly practical for industrial designers, consumer electronics manufacturers, and acoustic engineers who need to explain "loudness" to the general public without relying on confusing logarithmic decibel formulas. The Significance of the "118" Metric

| Metric | Unit Type | Linearity | Typical Use Case | | :--- | :--- | :--- | :--- | | | Logarithmic | Non-linear (10x power = +10dB) | SPL meters, hearing safety | | Phon | Logarithmic | Equal to dB at 1kHz | Comparing loudness of different frequencies | | Sone | Linear | Double the sones = double the loudness | Subjective loudness perception | | SONE118 | Linear + Offset | Calibrated reference curve | High-end DACs, studio mastering, Dolby Atmos calibration | sone118
