Have AIR Zound and other signaling systems tested / in use. The HORNIT is very noisy, but remembers the 'chirp' more like a car alarm as a bugle. In order 'to scare off the track' is the pedestrian HORNIT well suited; Motorists react but hardly or not at all to the audible warning. The HORNIT I discreetly mounted under the porch of my e-bike. The whole fits together well. However, in order to startle motorists going in my opinion nothing about the AIR Zound.
