What type of air horn is installed on the fire truck?

The installation of dual Hadley 6" round air horns on a fire truck is significant for several reasons. Hadley air horns are known for their robust construction and reliability, which are critical in emergency situations where loud, clear sound signals are necessary. The dual configuration provides a powerful and directional sound, ensuring that the horn can be heard over ambient noise, which is often present at emergency scenes or traffic situations.

These horns are designed to produce a distinctive sound that effectively alerts other drivers and pedestrians of the fire truck's presence, which is essential for maintaining safety on the road. The 6" size is also optimal for generating a sound level that meets legal requirements while being effective in a range of operational scenarios.

The choice of installing dual horns rather than a single rubber horn, metal trumpet air horn, or electric siren horn reflects a focus on operational effectiveness and compliance with safety standards. The combination of two air horns helps in maximizing sound output, which is vital during firefighting and rescue operations.
