Horn Power & Decibel Limits
⚖️ Regulation:
Most countries limit horn volume to ~100-110 dB. Anything louder is illegal for public roads.
Sound Safety
Louder horns can cause panic or hearing damage. Smart relay use can allow dual-tone without crossing legal limits.
The purpose of a horn is to alert others to your presence, not to startle or harm them. Excessively loud horns can cause hearing damage at close range and create panic reactions that may lead to accidents.
🧠 Real-life Scenario
You install a truck horn. An elderly pedestrian gets startled and falls — incident reported. Police measure your horn at 135 dB, well above the legal limit, resulting in a fine and requirement to replace it.
