Please stop. The federal government regulates how loud train horns on trains may be. The standard is 96 db at 100 feet, with an allowable tolerance of 4 db. There is a requirement for the manufacturers to test the horns to be within this standard. All your claims to the contrary will not change those simple facts. |

I know what you are, but what am I?

I don't know exactly how loud they are but there are a few logtrucks and dump trucks running around East Texas that have them and the will scare the heebeegeebees out of you when they sound them off.

+1. Interesting story: I was involved in a very small way in the early '80's of a large building in the PNW designed and constructed to "shout" at large satellites. The building walls were at least 4 feet thick heavily reinforced concrete. The purpose was to test the satellites for launch on the Space Shuttle and their ability to withstand launch noise. The building test area was purged of air and backfilled with, I think, nitrogen. The dB level they used to "shout" at the satellites? 180 dB. |

I never knew the exact db, but they are damn loud. How many have you had one blast in your ear while standing on the front of the engine. Bought kicked the shit out of the Engineer cause he did it on purpose. Also got stuck on an old UP engine every other day for 2-3 weeks where the horn was on top of the engine near my window. Hot as hell in the summer, loud ass engine, open window, loud ass horn, earplugs, radio turned up all the way, could barely hear the radio, and everything was still loud as hell. Sorry for the rant.

HOLY CRAP!
I will be buying a set of air horns like this right fucking N O W OMFG HAHAH! I thought those POS air horns I got from Autozone were funny to nail people with. I was asking my father who is a Locomotive Engineer and he said he can't get me any ![]() A+++++++ all the way. I can't wait to drive past the Golf Course for the next guy teeing off and laying in to that horn. |

Spinning this another direction...
How loud would the "ping" from a submarine be? I understand if there was a diver in the water when they "ping" it would be very harmful. Louder than a train horn AND a car stereo in the loudest stereo competition? Or in that case would frequency, how sound travels in water, and db's be the factor? |
|
I have a set of three on my frightliner with the tredel valve total cost was about 250.oo for the total set up you can get the horns from any petro truck stop and the tredel valves at a chrome shop use 1/2 " hose they need volume to sound right. And yes there loud.

I read that down in GA you need a proof of purchase if you have them because they were having problem with people stealing them

Sorry about the hijack, but who gets offended at this? --->
![]() Some people need to lighten up. Seriously. This is the internet, not a murder trial. And Inbox, if you could stop your whiny negative attitude for a moment, maybe you could provide some type of reasoning as to why a train horn "has to be at least 180 db". Several people have already pointed you towards evidence to the contrary. Why don't YOU post the db readings since you are so adamant in your opinion? ![]() |

I live in Norman Oklahoma and we have 28 trains per day,thats about one every 45 min or so! We have had several students die by train,so the trains lay on the horns very heavy when they come through here!
A real bitch durring summer months when we like to keep our windows open(dogs react quite verbose)and we pay for it! When you get where you can sleep through that then you lose your edge,you need a Dog or alarm! I think it sucks big time! Too loud!! Bob ![]() |

I'm no Sonarman (I worked in the other end), but I think it can be varied. The only active sonar I ever heard from inside the boat wasn't very loud and it sounded more like a musical scale. Doo-doo-dee-deet! Sounded about like someone was playing a flute in the room, and about the same volume. They did, however, hang safety tags on sonar when divers were in the water, so I suppose it could be dangerous... |
|
|
The average active Sonar blast is over 3 million watts of energy transmitted into the water at any given time.Since sound propagates better through water than air,I would say it's well over 180db.When there is a swimmer attack,the first thing they do is go active on sonar.They say the swimmer literally floats to the top,usually dead.

Thats great tagline material. That K5LA is nice, but I bet you need a big tank to run those! |

There's only one asshole in this thread thus far... go find a mirror. |

Its the damn wavelength and frequency of the sound that carries it so far, not necisarrily the deicbels (power). Weather conditions also play a role.

My stepfather had an air horn from a semi in his ... wait for it ... '78 MGB!

So has anybody put a set of these on a superduty yet?
How much would it cost to get a set of horns, a compressor and a tank? -dan |

Yes Also, from the groverairhorns.com site: Here are independent DB Ratings sent via email: DB Ratings at 100 Ft. Leslie S5T-F 116db Nathan K5 115db Nathan K3 114db Nathan M5 114db Nathan P5 106db Nathan P3 103db Grover 1275 103db Omega 3000 103db Buell Blasters 103db Grover Truck Horns 101db This should pretty much kill the "180 dB" BS once and for all. |

I've seen those at the Iowa-80 truckstop. You can also get them on eBay any day of the week, as there are a lot of people selling them. While very loud, and even advertised/sold as "train horns", they aren't something you will ever see on a locomotive engine. Leslie, Nathan (airchime), Prime, Wabco, and Hancock are the major manufacturers of locomotive air horns. |

Folks, dont forget, these horns have a different "style of sound" to them. While one may be louder than the other, the ones that arent as loud have sound that is more noticeable. As a railfan, I spendalot of time trackside or at yards, so I hear alot of train horns. I can tell what horns are on what locomotive by the sound.
All the ones listed below by Merlin have different sounds. ![]()
The Leslie S-series have more decibels and just have sweet sound to them. They arent harsh on the ears at all. Nathan K5-series is the sameway, but they dont have quite the sweet sound of the Leslies. However, a K5LA or the newer K5LAL, K5LAA, etc will hurt the ears. Alot of Hoggers are complaining about these new horns being too loud. Nathan K3-series is the perfect train horn for your personal vehicle. I think you can upgrade them to K5-series specs. They are much more affordable. I dont recall evewr hearing a Nathan M5. Nathan P5. Ha ha haaaaaaaaaaa! Daddy like. Not quite as loud as some of the others, but it has a teeth shattering sound to it. The only train horn that really hurts me. Its a true MF'er. The older cast iron ones are the best. This would be the train horn I'd mount on my truck. Nathan P3 is a damned nice horn. They have a mean sound to them, but never seem to hurt me. Another good choice. A good friend of mine, Ken Fitzgerald, website, including train horns. |

They are advertised at over 100dB about 100 ft from the engine. Seems much louder though...
![]() M5 Whistle Many years ago, I mounted a mini faux train horn in my car. I had to be rather judicious in its use because it REALLY worked. More than once I really startled a slothful or careless driver. ![]() |

Yes. It is a geometric increase, not even close to linear. A 3.0 dB increase doubles the energy of the signal. A 6.0 dB increase has four times the energy, and 9.0 dB is eight times as powerful. NOTE - Energy content and perceived volume (loudness) are not the same! At normal noise levels it takes huge increases in energy for the volume (loudness) to double. When things are very loud already, the energy graph for increasing dB levels goes nearly vertical. |

![]() They're FUCKING LOUD!! ------ The use of train horns is federally regulated by the Federal Railroad Administration (FRA). Beginning June 24, 2005, the Final Train Horn Rule requires trains to sound horns at a 96–110 decibel level for 15-20 seconds as the train approaches all public at-grade crossings. link |

Just the ticket for the bimbo applying lipstick or bumping gums on the cell phone during a green light!!!
![]() I know you can hear a train coming into my town 3 miles away with one! |
|
Shit! I need a set of those!! I'd never hit a deer again!!
Bambi would not stop unitl he was in the next state if hit K5LA on my vehicle!! |
|
|
|
gaahhhhh yeah they're loud...
Bought my new house - nice and quiet, out in the sticks, right? WRONG. When the trains come through (they're over a mile away in wooded, hilly terrain) it is still quite loud... And with the bare trees now it's a little worse, but we obviously aren't spending time outside right now either. |
|
A train horn is loud. I watch trains from time to time and I can tell you up close it is louder than you think. At night I can hear the train horn from miles away and I do not live that close to railroad tracks.

These are some othe grat train horn sites.
Diesel Air Horns Five Chime Consultants Railroad Locomotive Airhorns |

Loud enough for a wolf to hear it four to five minutes before the train reaches the crossing a half mile away.
|
|
|
|
I don't know how loud they are but I do know that I was just fired for not blowing the damn thing long enough.
The new rule states that the locomotive horn must be blown a minimum of 15 seconds until the leading wheels are over the crossing. 15 seconds is a long fucking time when you traverse 400 crossings a night. |

In railroad lingo, "fired" usually means given a suspension without pay. It is such a common discipline that many employees have job insurance that will pay them in the event that they are "fired". "Dismissal" is how a railroader really doesn't want to be disciplined. |
