Guest guest Posted July 10, 2000 Report Share Posted July 10, 2000 back around 1980, did a study on siren sound levels published in the Journal of Environmental Health, it did look at the frequency range that was produced by the different siren modes (wail, yelp, and hi-lo). However, the study was directed at the sound level and possible hearing damage; also at compliance with OSHA regulations regarding sound exposure. I don't have copy of the reprint anymore, but it should be available through a library. The work was done at Eastern Kentucky University. _______________________________________________ Why pay for something you could get for free?

Guest guest Posted July 10, 2000 Report Share Posted July 10, 2000 Gene: There was an article published in JEMS some years ago on just this subject. I no longer have issues that far back, but I think it was in 1992 or '93. As I recall, the findings were that wail is most effective. Yelp was significantly less so and other " cute " siren sounds were considered ineffective because they were often not even recognized as a siren. I'll see if I can track it down, but you might see if anyone you know has a JEMS archive dating back to the first half of the last decade.

Guest guest Posted July 10, 2000 Report Share Posted July 10, 2000 Agree with Dave about the hearing loss. That's what prompted me to start looking into frequency effectiveness, since it's high-frequency loss that I have. From years of being underneath the speakers. The Qs can easily be mounted on a bumper extension. has extensive experience with them mounted there at DFW airport where he worked for many years. They were the only thing that worked in the high-background-noise envirnment there. I would like to see a graph of the frequencies generated by the Qs as compared to the electronics. I'm not a physics person, so I may not even be asking the right questions. Somebody help. Gene Gandy Quote Link to comment Share on other sites More sharing options...

Guest guest Posted July 10, 2000 Report Share Posted July 10, 2000 I have been told that the wail is better, because it hits a broader range of tones.

Guest guest Posted July 10, 2000 Report Share Posted July 10, 2000 Barry: I, for one, advise against mounting sirens on the lightbar ABOVE YOUR HEAD. Not only do the people you are trying to move get a good dose of the ol' sonic disruptor (ah, the Q2. The only siren that increased your speed by 5 mph by turbo thrust!), but so do you, your partner, and both your ears. Today I suffer a significant level of permanent hearing loss (nerve deafness) from many years of such exposure. I have been trying for years to decide if my attorney and I should plan on taking possession of Federal Light and Sign, but he'd probably get the bigger half. If you have to mount them there, I strongly advise that all crew members be required to wear hearing protection while traveling in Code 3 mode. I had a shirt-tail kid partner about 25 years ago who always wore firing range ear muffs on calls. I used to laaaauuuuggghhh! Well, I'm not laughing any more.

Guest guest Posted July 10, 2000 Report Share Posted July 10, 2000 Back in Crockett we had one mounted on the overhead bar (complete with a Federal speaker and pair of bubble-gums) on a 73 low-top Surburban. We could rattle the glass downtown and once we had a police escort in Tyler (the federal went out and we needed a little help from the local police), we used our Q2 siren to move traffic for the escort in front of us. Man, those babies were great. I wonder if you could mount them on a push-bar if it had enough clearance from the bumper outward to miss the grill?

Guest guest Posted July 10, 2000 Report Share Posted July 10, 2000 Dave, agreed. The ambulance we had with the Q2 on the roof was just because that's the way they did things back in the early 70's. Everything I've specked, installed or worked out of since the mid-80's had all the siren speakers either under the grill or on the bumper. And you are so right about hearing loss. WHen the siren was on, either of them, communications was through shouting and hand signals. When the Q2 was on, you were thankful to be in the back of that old Surburban because even through it was loud, at least you were behind the sound and not in front or under it. And I'm not laughing about the hearing protection either. So hit the switch and pass the headphones.

Guest guest Posted July 11, 2000 Report Share Posted July 11, 2000 Back in the early 70's I worked for an ambulance service in Louisiana ( I won't say where since this person did not do very well in Texas) that had 3 (yes I said three) Federal Q2's mounted on the roof of the old Pontiac Catalina station wagons we were using back then. When you hit the buttons one at a time, you sounded like all hades breaking loose, and comin' down the road. Ed Brando Quote Link to comment Share on other sites More sharing options...

Guest guest Posted July 11, 2000 Report Share Posted July 11, 2000 : I have some posed photos of Ray Crowder 424, which had one of the first six modular ambulance boxes mounted to a 1975 (or was it 76) Ford chassis. This was the rig in which Capt. B. (who now only drives jet powered flying ambulances, th' lucky dawg!) and I terrorized the citizens of South Fort Worth back in the bad ol'days. I scan 'em and send 'em if you like.

Guest guest Posted July 11, 2000 Report Share Posted July 11, 2000 Gene: I know that the highest frequency response of the Q2 is lower than that of most electronic sirens. The worst damage to human hearing from these beasts appears to be in the higher frequency range that is common to both types of siren. Either type packs enough decibels to shoot those little sensor fibers in the inner ear all to hell. Sadly, the damage typically involves the higher-frequency portion of the human speech range. This is why it is characteristic, so the audiologist told me, for people so damaged to mainly notice it as difficulty hearing what other people say. I wonder if one of the university physic departments could do that type of measurement, maybe as a student project of some type? Although I'm sure that someone somewhere has already done that work and has that data. Dave Re: Siren Sounds > Agree with Dave about the hearing loss.

How many of us that teach in EMS (who are already effected) put an emphasis on hearing protection to our students? Granted, noise standards have changed, but why risk damage unnecessarily?

Guest guest Posted July 11, 2000 Report Share Posted July 11, 2000 Dave, That would be great.....When I went to work in 1991 (all of a sudden I'm old too!) we still had 1 gas truck that would haul a*% of course, you had to refuel after each call too.
