Sone Scale //free\\ Jun 2026

❌ – You can’t measure sones directly with a basic sound level meter; requires loudness calculation algorithms (e.g., Stevens’ Mark VI or Zwicker method). ❌ Frequency weighting matters – Sone values depend on how the sound spectrum is processed; different methods (e.g., ISO 532 vs. Stevens) can yield different sone numbers for the same sound. ❌ Less common than dB(A) – Many consumer products still list only dB(A), making cross-comparison difficult. ❌ Assumes a standard listener – Individual hearing variations (age, hearing loss) change perception, but sone is an average. ❌ Not ideal for tonal or impulsive sounds – The calculation can be less accurate for pure tones or very short bursts.
