Sound
| Category | Metric | Target (Sleep) | Target (Office) | Why it Matters |
|---|---|---|---|---|
| Ambient Noise | Continuous dB | < 30 dBA | < 45 dBA | Prevents micro-arousals; maintains “Deep Work” focus. |
| Peak Noise | Lmax (Sudden) | < 45 dBA | < 60 dBA | Sudden spikes (sirens/thumps) trigger instant cortisol. |
| Low Frequency | 20Hz – 250Hz | Minimal | Controlled | The “Hum” from AC or traffic; causes subtle systemic fatigue. |
| Vibration | Peak Velocity | < 0.1 mm/s | < 0.2 mm/s | Detectable by skin receptors; prevents deep muscle relaxation. |
| Sound Color | Spectrum | Pink Noise | Brown Noise | Masks external spikes while supporting brain-wave stability. |
