Understanding Car Horn Noise Levels
Car horns produce 100-120 decibels at close range (inside the car), with levels decreasing rapidly with distance.
Is 110 dB Dangerous?
At 110 dB, OSHA permits only 1.5 minutes of exposure. However, horn use is typically very brief (1-3 seconds), making hearing risk low for most people.
Key Safety Facts:
- Safe exposure time: 1.5 minutes without protection
- Hearing protection needed: Not practical, but minimize use
- OSHA guidelines: OSHA permits 1.5 minutes at 110 dB

Frequently Asked Questions
Can car horn cause hearing damage?
Brief horn use poses minimal risk. Repeated close-range exposure (such as in traffic jams with constant honking) could contribute to damage.
How can I reduce car horn noise?
Use horns only when necessary, avoid aftermarket extremely loud horns, or cover ears in prolonged honking situations.
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 horn use, but extended honking exposure warrants caution.
