Understanding Heavy Traffic Noise Levels
Standing near busy roadways or highways typically exposes you to 70-85 decibels, with 85 dB common in very heavy traffic conditions.
Is 85 dB Dangerous?
At 85 dB, you're at the OSHA threshold. Brief exposures (walking along a busy street) are safe, but living next to a highway or working in heavy traffic daily requires consideration.
Key Safety Facts:
- Safe exposure time: 8 hours at 85 dB
- Hearing protection needed: Recommended for traffic workers and delivery personnel
- OSHA guidelines: OSHA requires hearing protection for 8 hours continuous exposure at 85 dB

Frequently Asked Questions
Can heavy traffic cause hearing damage?
Brief daily exposure (commuting, walking) will not cause damage. However, living or working in constant heavy traffic noise for years may contribute to hearing loss.
How can I reduce heavy traffic noise?
Use sound barriers, live farther from roads, work in quieter areas when possible, or use hearing protection for extended exposure.
What decibel level requires hearing protection?
According to OSHA, continuous exposure to 85 dB or higher for 8 hours requires hearing protection. For brief exposures, no. For traffic workers or those exposed 4+ hours daily, hearing protection is recommended.
