Wink Jeepers this horn is loud but can you get them in the US?

I really want to get one of these - www.thehornit.com. It's just what I want for commuting in NY, but my local bike shop had never heard of it. Anyone come across it?

Thanks in advance

Didn't find any US based distributors. You could buy directly from them; however, it didn't appear to be a secure site while checking out...

Looks intriguing. Their site does say it ships worldwide.

That said, have you considered the Airzound horn? http://amzn.to/zM8yn1 Not sure what it's dB rating is vs. the one mentioned, but it's pretty loud, and runs off compressed air (just use your tire pump to refill). It's what I have on my bike and I've found no problem getting driver's attention with it when needed.

Airzound is 115 dB - I like the fact it is air powered not battery, but dislike having the air bottle.

That Hornit looks pretty smart, might just have to get one.

BTW I am in the UK, and accept PayPal - so if anyone is interested, I could make some enquiries re international forwarding. If you are interested - send me a PM.

I rather have a battery powered one as well to rid of the bottle but the Airzound has the oh you know "freight train coming through" effect

Got to say I agree with you, rather have something that sounds like a horn than a kiddies laser gun

I wouldn't waste time on this. It is not 140dB, maybe 100dB and this unweighted. Airzound, as one example, is well louder. It does not sound like a horn - would generally make people hearing it disoriented. In addition, people can have a hard time identifying the direction for such a high pitch.

There is a point beyond which you could be liable for causing an accident. The Airzound sounds like a big old truck horn, and its the same loudness, so I think you'd be safe in that respect with one.

You'll only need to honk it once. That kind of sound also is loud enough that it can be heard for more than a mile, especially in the direction the horn points.

And of course many bicyclists carry pumps as well. So, it should be possible to use one so that your horn could be recharged if that's needed.

I think one charging should last for multiple honks.

Actually, its low frequency (bass) sounds that are very difficult to locate. Because the wavelength is so substantially larger than the dimensions of our ears they tend to go around objects in our homes and vicinity.

Infrasound (sound below the lower range of human hearing, which hs been used as a weapon in warfare) still can be directed using phased array generators, and will penetrate almost anything except a sealed concrete blockhouse. Infrasound at around 7 Hz will cause a feeling of forboding and rapid nausea.

I think that there are problems with directional identification at both extremes. Note what happens when a watch alarm or even a high-pitch phone ring goes off within an audience or at a meeting. You suddenly have a number of people checking their pockets. For this particular device they seem to mix two frequencies and I suppose the lower of the two is likely to help somewhat.

Bump. Anyone have any additional info on this thing? Thinking about getting one, AirZound is a giant fail for my commute as it stops working below 30 degrees even if pumped to maximum. It's not the air pressure dropping in the cold, it's the diaphragm in the horn itself stiffening or something. I tested this by putting the horn and the bottle in the freezer separately. Cold bottle, warm horn = "PHOOORNK!" Cold horn, warm bottle = "wheet?"

Oh, and any single frequency is hard to locate, low or high. Multiple frequencies propagate differently from one another so are much easier to locate, which is why car horns and train horns are multitonal. The Hornit is multitonal so it will be easy to locate.

Sounds like the bike horn made for NYC

There's the MegaHorn which seems similar.

I actually just mounted a car horn after giving up on the AirZound, which as mentioned is useless in low temps.
