Delta AirZound and Loud Bicycle Horn comparison

We honked the horns outside the windows of a real car without adjusting the volume. Listen with headphones and picture yourself sitting in that drivers seat, how would you react?

Research shows that people react the fastest to the sound of a car horn compared with other sounds, so Loud Bicycle horns are designed to sound just like car horns. The special double-pitch sound of horns also allows people to hear where the sound is coming from whether or not they see a bicycle.

Loud Bicycle horns are powered by USB rechargeable lithium ion batteries with a charge lasting 2-4 months while the AirZound is powered by a canister of compressed air which you hand-pump before you ride. You can get about 30 seconds of honking time out of The AirZound though the volume drops off after the first few blasts. You can adjust the volume with the AirZound, but to lighten the impact of the Loud Bicycle horns you need to tap quickly on the button.

The Loud Bicycle horns are can be used in rain sleet and snow, but must be stored indoors when the weather gets below freezing. The AirZound starts to lose performance at around 40F (4C)

Loud Bicycle horns use a remote trigger which means you can place the button where it will be most convenient to use. The 2.5ft button cable extensions make Loud Bicycle horns easy to use on recumbent and cargo bikes. The AirZound trigger is attached to the horn so must attach it to your handlebars and you might need to lift your hands from their regular position in order to honk.

  1. Every split second is important when braking. The sooner the driver brakes, the safer it is when avoiding a collision. Even if you do get hit, you're better off if the speed of the impact is smaller. It's much safer to be hit at 30 km/h than at 50 km/h. That's why the designated bike routes in Vancouver are 30 km/h. I like the idea of car horns. It tells people how important it is to avoid crashes even if you're in a bike. Drivers will hopefully be more cautious next time. The importance of getting hit doesn't decrease just because you're not inside a heavy vehicle. I'm interested in the research about how fast people react to car horns.

    1. Great comment Brian. We discussed the research on reaction times and have the graph about the 30/50km safety difference in this blog post:
