Noise Levels and Safety
Protecting Your Hearing
Learn Safe LimitsNoise-induced hearing loss is preventable but irreversible. Understanding safe exposure limits and using proper protection can preserve your hearing for life.
Common Noise Sources
| Source | Level | Risk |
|---|---|---|
| Normal conversation | 60 dB | Safe |
| City traffic | 80-85 dB | Extended exposure risk |
| Power tools | 90-100 dB | Protection needed |
| Concerts, clubs | 100-115 dB | High risk |
| Firearms | 140-170 dB | Immediate damage |
Conclusion
The 85 dB threshold marks where hearing damage begins with prolonged exposure. Each 3 dB increase halves safe exposure time. Ear protection (reducing 15-30 dB) is essential for loud environments. Once hearing is lost, it cannot be restored—prevention is the only solution.
