Boat horns are required to produce sound levels of at least 110 decibels (dB) at one meter for vessels over 39.4 feet (12 meters) in length, according to the International Regulations for Preventing Collisions at Sea (COLREGs). For smaller vessels, the minimum sound level is generally around 90 dB. These requirements ensure that the horn can be heard clearly over ambient noise, helping to prevent collisions and enhance safety on the water.
