Understanding Thunderstorm Noise Levels
Thunder can reach 100-120 decibels depending on proximity to the lightning strike, with very close strikes potentially exceeding this.
Is 120 dB Dangerous?
At 120 dB, hearing damage can occur rapidly. However, thunder is typically a brief exposure (2-5 seconds per clap), so immediate risk is low unless you're very close to a strike.
Key Safety Facts:
- Safe exposure time: 7.5 minutes without protection at 120 dB
- Hearing protection needed: Not practical, but seek shelter from storms
- OSHA guidelines: OSHA permits 7.5 minutes at 120 dB

Frequently Asked Questions
Can thunderstorm cause hearing damage?
Typical thunderstorm exposure is unlikely to cause damage due to brief nature. However, extremely close lightning strikes can be harmful.
How can I reduce thunderstorm noise?
Seek indoor shelter, move away from the storm, or cover ears during very close strikes.
What decibel level requires hearing protection?
According to OSHA, continuous exposure to 85 dB or higher for 8 hours requires hearing protection. Not typically necessary for normal thunderstorm exposure, but storm chasers should consider it.
