Wanna make it louder? Make or buy a blower, even a shop vac and force it into the intake making positive pressure, aka "supercharging the siren" this is the method of the Federal Signal Thunderbolt and ACA Hurricane
Or attach it with a air funnel to the big-ass bumper on my truck. Let's see how loud it is at 60 MPH!!!! Now SUBSCRIBE ALREADY PEOPLE - Has this man not done enough cool videos YET to earn your subscription? What are you waiting for, a scroll sawed, personalized invite?
Bradley Brand That wouldn't generate near the same sound pressure. Blowers such as those generate over 250 CFM of airflow at over 9-10PSI. Uncompressed free air wouldn't work that way with your truck.
I'm sure his neighbors just love him to pieces... I love the homemade air raid siren, but I won't try to repeat his efforts, as I live in the city, and don't like meeting the police that much...
It's funny how he was like "turn up your volume so I can hear my voice," and I was like "nah," and then turned down the volume instead. About as loud as expected
Him putting up ear protection was somewhat of a give-away that it might not be very clever to turn up your volume to listen to this. After all, an air raid siren was designed to be bloody loud. You were supposed to hear it from quite the distance away, because you know, air raid and all that.
ok .. so i have this pretty sweet sound system .. i normally have the volume on 12 .. when you asked to adjust it , i put it on 76 , sounded like normal .. then WTF OMG JEEEEEZUS !!!!!!!! i think i woke up the neighbours !!!!!
No idea why this guy set a trap at the end of the video, but don't turn your speakers up when he tells you to.. Turn them down until you can barely hear him talk.
He tells you to turn it up so you can hear him talk, then turn it down before he switches the alarm on. I don't see how it's a trap if he's in a small space with a loud machine and puts on ear safety equipment, saying "Okay, here we go."
just "no"? can you please explain to me how yours is different, in essence, from these horns? www.directindustry.com/prod/klaxon-signals/high-power-sirens-15275-954623.html now, don't get me wrong. the fact you built this by hand and with wood is very impressive indeed. i'm not trying to take away from that. just wanna know the difference between yours and a klaxon.
***** The siren your link leads to is a Klaxon brand Siren. Confusing, possibly, but both are sirens, and not klaxons. A klaxon uses an electromagnetically oscillating plate to create its sound, I believe
Jim H ***** Original Klaxon-brand sirens used a steel diaphragm struck by the teeth of a spinning cog. They also used horns for better impedance matching. They are known for producing that "ah-oog-ah" sound you hear in old submarine films.
In order to make it louder, you need to match the acoustic impedance of air. You can do this by adding horns that convert the low impedance output of the siren to the high impedance of the air. Once matched, the power transfer to the air will be far more efficient and that 1.2kW will be absolutely deafening!
G3RMANARMY 1200W is equivalent to the sound of a medium DJ system, but those have to produce a lot of bass frequencies. If it were putting all of that energy into two sounds which contain most of their energy in the middle of the audio spectrum for human hearing where it is most sensitive, then it would sound orders of magnitude louder!
or, ... Place a Microphone beside the siren, now, Conect to amplifier, then to another amplifier, then to another, then another, all set to -0DB (from -DBs) then another amplifier, now connect atleast 2 1200Watt speakers, This will burst the ground of loudness >_
It is a much less offensive note, thats for sure, although, sirens are meant to be offensive to the ears, so I suppose that should be expected. Man, that note is so close tho... I bet a 7/10 would give you that fear of god feeling a siren is suppose to give you :P
What was decibel range of your siren? Have you ever had it checked for range? did it pass 120 Decibels? As far as I know, I think the highest decibel range recorded was like 160 Decibels, but after googling "the loudest sound on earth... the highest sound was rated at 220 Decibels.. from the eruption of a volcano...
Good idea but megaphones have a max volume they can reach, they don't just flatly increase any sound otherwise you could use them to make an obscenely loud sound by linking a bunch together. this siren is probably louder than any megaphone
You could use an acoustic megaphone. A lot of the professional ones actually "horn load" the output of the slots e.g. put an expanding trumpet/funnel of air on the end of the slots in order to compress and move more air! And those are REALLY LOUD!
i have that air raid siren its on a switch and just to make it not so loud, the air raid siren itself has a switch to change the rpm. I have it on 750 rpm so its loud enough (about 100 dB from 5 meters away from it) So i use the siren to tell my FAMILY WHEN ITS LUNCH TIME OR SOMETHING OTHER BECAUSE THEY ARE ADOUND THE HOUSE EVERYWHERE. Oops sorry for the caps.
So impressed with your skills in many arenas. A man after my own heart. I can see you've built almost everything custom in your shop, too. I used to build pipe organs, was the cabinet maker, so have a deep appreciation for what you do. Thanks for sharing everything you share.
You should try a decibel reading at 100 feet! 100 meters is WAY farther than 100 feet so, this may be capable of 120 decibels at 100 feet. You could cut a can or something and make it a projection cone and make it rotate! That could be your siren making you BIG bucks!!!
I have earbuds and when u told me to make the volume lower I did to max then my ears started to bleed and my dad came running to my room HE HEARD THE NOISE
Your 'more cowbell' needs more power 💪 In any other way great work! I think the real ones blow a bigger air volume, so I think you'd need a bigger motor and a bigger fan set, either wider in diameter or thicker.
I needed to put a little fence around my house so the alarm does not scare anyone nearby and also It spins! meaning the siren as it sounds, spins around and around and around and around and around.
The audio is omni-directional coming out. If you put some kind of horn to help make it uni-directional you'll get a lot louder of a sound. Thats why air raids have horns, to direct all of the sound in one direction at the same time helping amplify it.

7/10 port sirens exist, and they are terrifying sounding. HOR made one.
Marcus Toroian well 10 is 3 away from 7, so it would be a devil's interval. It should inherently sound pretty dark :P
Marcus Toroian It's a minor sixth. A second inversion (6-4-1) major chord.Very pleasing sound.

Add a megaphone to it.
Good idea but megaphones have a max volume they can reach, they don't just flatly increase any sound otherwise you could use them to make an obscenely loud sound by linking a bunch together. this siren is probably louder than any megaphone
so add like 20 megaphones, a'la Bart

You should try a decibel reading at 100 feet! 100 meters is WAY farther than 100 feet so, this may be capable of 120 decibels at 100 feet. You could cut a can or something and make it a projection cone and make it rotate! That could be your siren making you BIG bucks!!!
