Inputs
Calculation
- 1NIOSH 3-dB exchange rate: each +3 dB halves the safe time
- 2T = 8 ÷ 2^((85−85)/3) = 8.00 h = 480 min
- 3Used = 60 ÷ 480 = 12.5%
- 4Remaining quota: 7 h
- NIOSH / WHO anchor: 85 dBA for 8 h is the daily ceiling; +3 dB halves it (88→4 h, 91→2 h, 94→1 h, 100→15 min).
- Follow the 60-60 rule: volume under 60% of max, 60 min per session, then rest 10-15 min (Beijing Health Commission).
- In metro or bus noise, earbuds often run 85-90 dBA just to hear clearly — noise-cancelling headphones help.
- Never sleep with earbuds on; use a bedside speaker with a 30-min timer instead.
- Warning signs: persistent night tinnitus, always raising volume, asking people to repeat. Get a pure-tone hearing test.
- Sudden hearing loss within 72 h is the golden treatment window — see a doctor immediately.
