I've had good results with two different horns on my cars. Both made by Stebel, one is an air horn called nautilus and one is a twin electromagnetic pair called Magnum. Both claim high noise the nautilus 127db and the Magnum pair claims 115db. To my ears they are a similar noise level but the nautilus is a high tone air horn type like a stadium horn and the Magnum is a more aggressive "GET OUT THE WAY" type.

[@h8GW]

@Eric Duckman You know you can just buy some reputable Chinese cells from reputable sites like 18650batterystore, instead of off eBay right? And besides, Project Farm already tested this. Or are you trying to say they should test how close the actual capacities are to the advertised ones of the reputable 18650s?

60 dB Hurts my ears a bit

[@AntonGudenus]

The reason 194 dB is the limit in 1 atmosphere is because of the wave troughs/rarefactions clipping into vacuum. So the full wave can no longer form, due to there being no lower pressure than a full vacuum and the opper pressures having to work with 1 atmosphere of air. Though in reality and with real air an its thermodynamic properties the waves start distorting non-linearily from around 150 dB already. To get beyond those 194 dB you need extra air-pressure from somewhere. And that somewhere in practical terms is generally an explosion producing a whole lot of localized extra gas volume.

An interesting test for sure, but as their tones are not always constructive, interference will usually act to reduce their amplitude. If he had hooked multiple of the same horn up and tested that, there would have been a much greater chance to increase the amplitude. As this is the Torque Test Channel and not a The Who concert, I didn’t anticipate that kind of test. Was still happy to witness it (via VOD), and also happy I was not present even at distance in the industrial park they were testing it in.

Sadly with most school going teenagers on their bicycles wearing earpods these days, 96dB just doesn't cut it any more. You need to be louder than that or they just straight up won't hear you. Also the 117dB horns were the loudest I could find that worked on 12V AC and had an E-number. I wouldn't want some overzealous cop to suspend my registration because of a horn.

[@joeschmo622]

A lot of the trumpets themselves have a diaphragm which'll start to rust and cause air leakage, reducing the volume of the horn. I thought my (long gone) airhorns had an issue with the pump, because it'd just whirr away when energised, so after getting an identical set, I replaced the pump. Same dealy! Swapped back everything, so new trumpets with old pump, loud as I got the originals on day 1. Best I could do to prolong them is to drip oil into the hole where the hose goes, and onto the diaphragm through the sound opening. Then give 'em a few blasts to let the oil squish around and get into the contact area between diaphragm and trumpet. The pumps also wear around the seals, so cleaning the innards and reoiling should be general maintenance on those beasties, too, even though no one ever brings it up.

[@roysigurdkarlsbakk3842]

IIRC the default distance for sound measurement is 1m Edit: And don't forget - an increase in 3dB does *not* make it double as load. Yes, the effect needed to increase 3dB is 100%, but for sound to be audiable double the strength, you'll need to increase it by 10dB. Interestingly, 3dB is also the limit to which the average person can register a difference (lower or higher). People working with music and similar, can often differ between lower changes than 3dB, but those are mostly exceptons.

Yes and one other thing is the formula for dB correction at a different distance assumes an isotropic source which the horns clearly are not.

at 600dB it wouldn't just move someone out of the way with the shockwave. It would release about 1x10^48 Joules of energy. To say that's a lot of energy would be a significant understatement. It would literally vapourise the solar system into a rapidly expanding plasma (everything, the sun would be blown away by the energy release like you blow flour off a kitchen countertop), it's entirely like a few neighbouring systems would go that way too. Your "horn", over time, would be easily detectable across the entire visible universe with current technology. Of course in actuality putting that much energy into such a small item would like mean that it would collapse into a medium sized black hole.

It totally works and trips you out because they slowly zoom in from a very far and wide angle perspective on a dark foggy scene. You just hear the fog horn and see light sweep by. It's not until they get close enough you realize it's a Tahoe rotating on top of the light house with it's high beams on sounding the horn. I'm sure it's not real, but it still messes with your brain. It was probably just marketed to select regions like mine (New England), perhaps the Great Lakes and the Pacific NW. No one else would get the reference or have that lighthouse sound embedded into memory like we do growing up with it! LOL

The two dual horns likely exhibit what is called constructive interferance, which means their sound waves merge together and make a larger one, making it louder than just the sum of the two horns, or at least my guess

[@MikkoRantalainen]

I think constructive interferance can only cause twice the original waveform at max because when waveforms exactly match in amplitude and inverted phase, you get the maximum and that's only double the original. If the summed waveforms have different frequencies, the resulting oscillation in the sound may be something that the dB meter reacts to but I'm not sure why. The video didn't mention if the meter used A, B, C or Z weighting. I think the dB calculator on the computer probably matches only the Z weighted meter (which is the only one that actually meters the energy in sound, other more or less try to measure human hearing instead).

[@yesthisisdonut]

i suspect theanufacturer might have made the 2 horns have different pitches on purpose, as having 2 horns with matching pitches would potentially risk destructive interference if for some random reason, one horn starts off with inverted phase.

[@MikkoRantalainen]

@@kirkhamandy Yes, if the soundwaves interfere destructively that would result in silence. However, executing this in practice with two sound sources in two different physical locations (e.g. 5 cm away from each other) causes the silence to project "between" the sound sources and lobes of sound diagonal from the projected silence will see constructive interference and double energy (imagine waves in water from two separate objects but in 3D in air).

It's not the loudness alone, but the combination of tones that get their attention!

[@PyroYeet]

Always remember kids, decibels are logarithmic, meaning a +6 increase in decibels is twice as loud, +20 is 10x, so a 600 decibel horn would be about 10^25 or about 10,000,000,000,000,000,000,000,000 louder than a 100 decibel concert

[@HashDogg06]

You will probably find the Hella horn will increase a couple db once it is bolted to a sufficient part of the vehicle & the tone will usually change also. Should have got a truck horn & used a air compressor to see how much louder it is or even with the cheap car horns they usually get a lot louder.

New law: horns should sound as loud inside the vehicle as they do outside to discourage drivers from being assholes.

[@diogosimoes9068]

Hey, just wanted to let you know that the reason the dual horn and all the horns combined ended up being louder than expected is because that calculator you used to add up the volumes is wrong. It uses the 10dB=10x convention instead of the usual 20dB=10x convention. You can tell this is the case because, as you said in the video, an increase of 6dB means twice as loud, so two 106dB horns should sum up to 112dB, just as you measured, and not 109dB. All the other calculators and calculations you used throughout the video seems to be spot on though. Great video!

[@tallen917]

A great demonstration of inexpensive horns. Thanks for conducting the tests. The capacity of the air pumps may be a limiting factor. I designed a horn (known as a whistle on a commercial boat) system for an 85 foot passenger vessel. I used a 125 psi compressor, a 10 gallon storage tank and 1/2" air line to the whistle. The tank was mounted close to the whistle to reduce losses due to the airline diameter. It also required a pressure shutoff for the compressor and remote button in the wheelhouse to activate a normally closed solenoid air valve. It could be heard from 2 miles distance. As you can see the system would not be practical in an automobile. My point of all this is that if the air horns you tested had more pressure and flow they may have been louder. But of course the cost would be considerably more.
