So basically, departments have been getting this all wrong... *For intersections, the obvious solution is to use sirens that have greater sideways coverage, instead of just piling on more watts.* *Highways are the only situation where a 150-200 watt system will help, in other situations it's important to have a volume limit for residents and pedestrians.* - If you want to be more visible at long range, don't buy more lights. Change the pattern so it's a simple half-half pattern (or in-out if you've white lights in the middle). Perhaps an on-off every few cycles as well. But remember: the simpler the better.
You are correct! The many light patterns are fun, but most effective is plain ALL ON, ALL OFF at.tracting the unexpecting eye. Unfortunate that electronic siren speakers can be so forwardirectional. The mechanical sirenspread sound more around. Buthey are big and heavy and use much power.
Excellent explanation. Only issue with running dual tone is that you now lose the +6db from having a second speaker producing the same tone. Having one speaker run Wail while the other runs Yelp now gives you two different 124db tones only traveling 700 feet. Stick to a true 200w siren by running single tone in phase.
How about some videos detailing the differences and advantages between the Cobra Line and Apollo Line, like how the T6 are more intense as you look at them directly, but the Apollos are Brighter off axis. Also, Explaining the differences between the Apollo Extreme, Standard Dual Colors, Dual Color Flood, and Dual Color Arrow. I am regularly having to explain these differences to customers and a video with this type of production would be great!
Exactly. And in the city, it's only a nuisance. Inside my house I can hear the new ambulances coming from about 4 blocks away Sirens should have a highway and city mode!
@@finnk1289 Well, big cities are loud by themselves, and when you're in a car (especially modern, very sound proof interiors) the sirens need to be loud. Add listening to music in the car and you still can't hear them before they're tailgating you.
good job great video, i have been running a duel tone 400 watt siren with duel 200 watt speakers and several people have told me they can hear me much farther than some other vehicles , another think you can note that your side range at intersections is probably half of your front range, so instead of 700 feet its 350 feet, by using 200 watt that would make it 700 feet to side and 1400 front, which makes intersections much safer in which most accidents happen. thanks feniex you products are great, i love the apollo lights .
A 400 watt siren? Okay now that is way too much. Instead of increasing the volume in front, how about placing the speakers differently? I wish there were 180 degree speakers - maybe there are.
@@finnk1289 no it is not way too much it should be a standard for all emergency vehicles, very true you could run 4 speakers 2 to front and 1 to the sides but that is over kill
I see several comments about the 100W to 200W and the 3dB vs 6dB. Let me help explain. The delta between 100W and 200W of power, expressed in terms of relative power levels, is 3dB. The delta between 100W and 200W of power, expressed in terms of the sound pressure level (SPL) in pascals produced by that change in power level, is 6dB. Those who say there is a 3dB delta between 100W and 200W are correct. Those who say there is a 6dB delta in SPL when power is doubled (i.e., 100W to 200W) are ALSO CORRECT. It is very important to understand that dB is often used for different things, and it can give us different numbers, even though those numbers mean the same thing! In this case, a 3dB change in relative power is the SAME THING as a 6dB change in relative sound pressure level.
Thanks that was very interesting and very well presented. Maybe a how to install some of your products on say an Ford Explorer. That way we can see what you have how to install and then how great they look. Stay safe!
There's an error in your presentation at 4:03. The graph has 'dBs' above it. There is no such unit. It should say 'dB' - you don't pluralise abbreviations. Example - 1 dB, 86 dB. A letter added after dB is a reference, for example 'dBm' (relative to one milliwatt). Other than that, a good explanation about sound levels!
100w to 200w is +3db not +6db. In order to make +6db from 100w would take you to make 400w for the difference. Don't know where you got your info, but its incorrect.
being in both the audio and rf industry for many years I know these figures. building audio systems and wireless systems I use them often. not only professionally, but in play I suggest you go have a talk with your product engineers and development as your figures are incorrect.
How does speed affect db (loss) when driving at highway speeds... For example if I'm standing still or moving slowly a 60 db siren travels 2500ft but how far can it travel if I'm driving at 65mph?
I have the Fenix Storm Pro100 but I was only able to get my hands on a 200W speaker at the time. Would my sound quality improve if I used a 100W speaker? I only use the PA and the ghostbusters ECTO 1 siren in my setup. Thanks
+Feniex Industries But that still doesn't explain the comment at 2:41. Where does that come from? Do you have a link to a study or something? An louder sound IS higher sound pressure. SPL = sound pressure level.
so, if i have a 200 watt siren amplifier, with 2 speakers at 100 watts each, would i get the same distance as a single 200 watt speaker? or still the same distance of the 100 watt speaker
Thank you for this video! Insterestlingly enough, the siren system in China is in different format, the standard siren AMP uses 150W 8 Ohm in China (mostly), and I think the AMP and speakers you use is 100W 11 Ohm, so how do you measure between 150W 8Ohm speaker and 100W 11 Ohm speaker? I am actually using your Storm Pro 100W with the Chinese 150W 8 Ohm Speaker, I dont feel any difference between using it with the original 100W 11 Ohm speaker and the 150 8 Ohm Chinese speaker though, but do you think it will cause any harm to the Storm Pro unit?.
Is there any benefit to having two 100 watt speakers being powered by one 100 watt siren? If it is setup that way, does it bring down the decibel level or range?
You do know that 6 decibels is four times the sound output don't you. Every 3dBm is double the previous out put. 2x2 = 4 times. To be fair perceived sound is not quite mathematical and depends on the total output power. bm
Same. It just adds to the confusion. The new ambulances in my province are so loud they sound dual tone sometimes just because of the echoes off of buildings.
If I take you out on a few dates, buy you some drinks with dinner.... can you give me some visor lights, surface lights, controller, speaker and siren??
Great explanation of multiple, technical concepts in easy-to-comprehend method. Thanks!
The 150 million watt siren is one way to finally get people to move out of the way
Not sure even that would do it. Even duct tape won't fix stupid.

I believe the CHP uses a 200w siren. Those things are very audible at longer distance. But they are necessary since they mostly operate on Highways.

So what's better a siren that is bell shaped or the flat faced siren? And does the bell shape make it louder?
A siren with a wider output towards the sides is much more useful for clearing intersections. Instead of increasing the power, increase the coverage!
I have the Fenix Storm Pro100 but I was only able to get my hands on a 200W speaker at the time. Would my sound quality improve if I used a 100W speaker? I only use the PA and the ghostbusters ECTO 1 siren in my setup.

Nice, I have some friends who will be interested in this.
Where do you get the magic 195dB from? A shockwave is a pressure wave that travels faster than sound, not just really loud sound.
+Feniex Industries But that still doesn't explain the comment at 2:41. Where does that come from? Do you have a link to a study or something?
An louder sound IS higher sound pressure. SPL = sound pressure level.

great and good explenation
very nice explanation
so, if i have a 200 watt siren amplifier, with 2 speakers at 100 watts each, would i get the same distance as a single 200 watt speaker? or still the same distance of the 100 watt speaker
I would love this for my regular car!

good way to blow up your siren, you always use the speaker that matches the amp
great Video!!!!
Very informative video!!
Double your wattage, increase volume by 3db with the same speaker.
Is there any benefit to having two 100 watt speakers being powered by one 100 watt siren? If it is setup that way, does it bring down the decibel level or range?
Watch the video
How does 2 100w sirens play out?
Great comment lone star
So if i have a Typhoon Full Function siren with a 100W siren and I add another 100W siren will the combined output sound be 130dB??
103
You do know that 6 decibels is four times the sound output don't you. Every 3dBm is double the previous out put. 2x2 = 4 times. To be fair perceived sound is not quite mathematical and depends on the total output power.

You do know that when you ask a condescending question, you end it with a question mark, right?
Good video 👌👌
I never cared for dual tone sirens.
Same. It just adds to the confusion. The new ambulances in my province are so loud they sound dual tone sometimes just because of the echoes off of buildings.
What if I have 2 100-Watt sirens
Is this stuff for the States only?
Watts volts and ohms are metric
If I take you out on a few dates, buy you some drinks with dinner.... can you give me some visor lights, surface lights, controller, speaker and siren??
This is good
I want to mount a Chrysler Victory Siren in bed of truck to clear the freeway.
Chrysler siren is 189 db
its best to watch this muted
If only people used this level of science and common sense when talking about the jab. ie it’s not working!
Now I know.🤣🤣🤣👍
SCIENCE
So what's better a siren that is bell shaped or the flat faced siren? And does the bell shape make it louder?
Bell shaped is to project the siren in one direction, the square one is a compact version and it may not be heard as far as a bell shaped one
