To receive the verification, a product must undergo a 72-hour torture test in an anechoic chamber. Engineers measure not just peak output, but linearity across the Sone curve . If the product deviates by more than 0.3% in perceived loudness from the true Sone curve at any point between 0 and 483 Sones, it fails verification. | Specification | Verified Detail | | :---
