Nice cow horn on the ambulance

The problem with even three tones is that they could match music playing in the vehicle. The wide range of frequencies of Wail makes it stand out better. Wail is also detected by those with hearing deficits better than other sounds. Yelp may be the best sound, but Yelp has a tendency to panic some drivers. I added some capacitors in the Yelp tone generation circuit and slowed our Yelp a little. Adding "vibrato" to these tones is an interesting idea!

Liked for the cow, lol!

Thats why there are 3 tone's because you hear always hear atleast 1 of the tone's. And with 2 or 3 tone's you can hear very clear where's its coming from. Im not going to judge which siren is the best, because they are all just as good in their own way.

HAHAHAHAHAHAHA COW!! XD that was hilarious for some reason

I LOVE THAT COW!!!!

Interesting! I thought those were actual horns. Thanks, Wouter. From the very beginning, the unsteady "fluttering" of each tone of the siren sounds like a recording made on a cheap tape recorder. So funny to hear that cow. My pet pig would react to a certain sound I would make!

IS the cow in the car? :-}

Wow, random cow-age! MOO!!!

While I have never heard this tone here (the US)...it would sure grab your attention just as an air powered Martinhorn would. People would look around just to see what the heck was making it. (Ice Cream Truck jokes aside)

een koe op de achtergrond, geweldig :P

Very realistic 'bullhorn'!!

No, this siren is electronic made. I dont actually hear what you mean, but there's good possibility you hear the echo's and the soundvolume adaptations of the camera because of the cow. In real, the siren is just stable.

The "vibrato" is purposely done? How interesting! The ascending and descending frequencies of "Wail" is the best siren sound because it sounds at ALL frequencies within its range. The problem with the three-tone siren is that one or more of the tones could match music being played in the car.

Sounds like recording wow and flutter. The tones from the horns are not steady and even. Or do those horns have an unsteady air supply?

@bobzzz23 haha the ambulance XDD

Mooo! Mooooooo! lol cool vid

Was the cow responding to the horns? Dogs will often howl along with sirens. Why is the sound so bad? Interesting to hear that three-toned warning. Thank you.

I don't understand your language, but I sure got what you wrote here and am still laughing!

Ah, i think i get it. You mean the "wave" effecnt in the tone's. That is on purpose en part of the siren. Its because it grap your attention and you hear it through other sounds, like the car radio. There are many types of these 3tone sirens here in the Netherlands.

The ambulance is only in Middleburg the half clip

yes

tatütata-möööööh- XD

Interesting theory, Noone. I believe that Wail is best because it ascends and descends through ALL the frequencies. It cannot match any music playing in a vehicle. This ambulance sounds notes B-flat, d, E, d, which could match music. The low E unexpectedly stands out in this awkward musical triad, but not as much as Wail "sliding" up and down a musical scale. Has anyone conducted tests to see what catches the attention of the unexpecting ear? As an organist, I dislike this sound.

als of we nog nooit een ambulance hebben zien rijden..

Mooi filmpje! Geen koeien pesten hoor! Gr. Laurens

@avonrangemaster LOL
