Hearing Risk Assessment
Noise-induced hearing loss depends on both the loudness (decibels) and duration of exposure.
Safe exposure times (NIOSH standard):
| Decibels (dB) | Max Safe Time | Example Sound |
|---|---|---|
| 85 dB | 8 hours | Heavy traffic |
| 88 dB | 4 hours | Leaf blower |
| 91 dB | 2 hours | Power drill |
| 94 dB | 1 hour | Motorcycle |
| 97 dB | 30 minutes | Nightclub |
| 100 dB | 15 minutes | Concert, power saw |
| 103 dB | 7.5 minutes | Jet ski |
| 106 dB | 3.75 minutes | Ambulance siren |
| 110 dB | 1.9 minutes | Rock concert speakers |
| 115 dB | 28 seconds | Firecracker |
The 3 dB rule: Every 3 dB increase doubles the sound energy, cutting safe time in half.
Safe Time (hours) = 8 / (2 ^ ((dB - 85) / 3))
Tips for hearing protection:
- Use earplugs or earmuffs in loud environments
- Follow the 60/60 rule for headphones: 60% volume for 60 minutes, then take a break
- Distance yourself from loud speakers
