air horn hose length

I want to install a air horn in 2 days time .the location chosen for the compressor and the trumpets is longer than the supplied 2 feet hose. i want to add another 2 feet to the trumpets . will this have any effect on the sound ? do i have to hold down the horn button longer to get the same sound? will the compressor react instantly with the increase length in hose?"I'm So Loud It Hertz"

2 feet shouldn't make much difference. The problem with adding length is that the hose is liable to kink and that deffinitely will effect the sound. Airhorns react almost as fast as regular horns

hose length effects reaction time. Deisel horns are pressured all the timeI think I see Light!
