[@bait28]

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.

[@Alighierian]

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.

[@whemenocbeginnermusichistory]

Yup!

[@TomGlander]

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.

[@mgpvii]

Saw both the making and testing of the siren videos. They made me smile.

[@BoldUniverse]

Great vids of you making and testing the air-raid siren, enjoyed them both very much.

[@JimGriffOne]

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!

[@thenormalsteve5589]

Good explanation! He should really do that.

[@sWaRmBuStEr]

Thenormalsteve just imagine. if a 100 watt speaker gets you house shaking, what would a 1200 watt "speaker" do if it was as ifficent.

[@JimGriffOne]

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!

[@sWaRmBuStEr]

***** that what i meant basically!

[@thenormalsteve5589]

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 >_

[@MarcusToroian]

That port ratio

[@rich1051414]

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

[@MarcusToroian]

7/10 port sirens exist, and they are terrifying sounding. HOR made one.

[@rich1051414]

Marcus Toroian well 10 is 3 away from 7, so it would be a devil's interval. It should inherently sound pretty dark :P

[@closhnhex]

Marcus Toroian It's a minor sixth. A second inversion (6-4-1) major chord.Very pleasing sound.

[@MyRadDesign]

Awesome! As I recall, the real ones had a horn assembly that was driven to rotate slowly to scan the horizon to increase the sound level to make distant listeners notice the sound. Keep up the great work! Arlen

[@ImperialistRunningDo]

An "alarm" is sounded by raising and lowering the pitch (a sound we have all heard on many WWII movies). The "all clear" was given by keeping the same pitch.

[@jackferrie5485]

I actually legitimately thought my house was gonna explode

[@Bobstew68]

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.

[@shuriken188]

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."

[@Tom44224]

He never tells you to turn it down again before he switches it on.

[@splix85]

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.

phatrides222000 He did, but he didn't have any spare switches laying around

[@EarlyMonAF]

You may be able to amplify it by turning it into a compression driver. Enclose it with a forward facing aperture - located in the center in line with the motor shaft is fine - and then make a simple box horn to act as a megaphone. You're only interested in volume, not fidelity, so no need to muck about with flaring or anything fancy for a first pass. A compression driver has a smaller opening that the actual driver (hence the compression) so the aperture having less area than the total area of the open slots at any time ought to provide the desired results. Really loved the videos on this, many thanks, very inspiring!

[@jimh8063]

***** 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

[@nelumbonucifera7537]

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.

Add a megaphone to it.

[@klimpomp]

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

[@Iruparazzo]

so add like 20 megaphones, a'la Bart

[@TimpBizkit]

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!

[@chubbykitty21]
