View Full Version : proof of 80 hz rule!

I have been to alot of shows and many of the competitors are still using high notes. acording to wayne at a show in pitsburg he claimed to have a filter to WEED OUT anyone playing above 80. His rule is good if it can be proven to the competitors that his equipment will truley indeed detect the use of higher freqs. several cars that went through after the explanition of the filter still played high notes and nothing was said about it.also alot of the scores listed at different shows were posted with high notes.
its much harder to reach a high number with a low note due to wave length and other things.question, should wayne prove that he can enforce this rule before competion begins or just let it go on as it has been going and continue to let things stay as they are with a verbal rule with no proof of its enforcement or anything goes dont say noyhing let it be?

Dude, you are talking about the founder of this sport........ and how do you know what tone they were playing? We were at a show this weekend and one of the guy's trunk rattled so high pitched, that it sounded like it was playing 150hz....but he was playing around 60hz.....food for thought

then if the vehicle can produce its own freq. during competition, then would the mike also pick up the same note that you mentioned and then the competitor be desqualified for using the wrong note combined with his low note.THINK ABOUT IT.
as for the founder. nothing was implied as to him or his organization. I think that he does the best job of any group out there period.

You were questioning Wayne's authenticity, which does directly imply him. And what I said and the way you took it was two different things. They car sounded like it was producing a high note, due to the rattling on the outside of the vehicle. The inside of the vehicle was playing a 60hz tone.

The way it is supposed to work is that if you play a note over 80hz the equipment used by Wayne is supposed to red flag your run.I think what you are meaning to say is that it would be nice to see a car run through playing a 85 hz tone to see what actually happens and to see if it works like it is supposed to.I think this is a great idea.maybe Wayne could do it at the competitor meeting on Friday night to show how it does work and what it actually does during a disqualifing run.That way it puts any speculation to rest about if the filter does in fact work.And by doing it at the competitor meeting you could get all of that speculation out of the way there and not why the comp is going on.I have seen it where they will actually calibrate a set of mics after the qualifing is done and find out that lane 1 is 3 db higher than lane 2!So if you ran through lane 2 you got screwed....but there was bitching so you got to run back through.....what a mess!!!!!!Anyway i have faith that Finals will be a top notch show!!! http://www.termpro.com/ubb/smile.gif

The high note detection is not required at local shows.
The Term-LAB software with the detection feature has not been distributed to Term-LAB customers yet.
At the Finals, the software that we use DOES indicate the frequency where the highest SPL occurs. In addition, we have added several new features that will address mic linearity.
Microphones are non-linear by nature. You can take 2 exact mics and calibrate them at a given SPL and still see some deviation at other SPLs. Currently, all measurement systems on the market (that I know of) use a single point calibration. The new Term-LAB software uses Multi-Point calibration (we calibrate at 124, 134, 144, 154, and 164 db). A curve fitting routine is then used to ensure that the mic tracks the input level in a linear fashion. This results in mics that track each other exactly! No one else has this! This feature will practically eliminate lane-to-lane variations when Term-LAB is used with the new software.
This software will be available as a free update to Term-LAB users after the Finals.

Along with the filter we must also remember that you must use the dB Jams CD...which as I recall does not include tracks that include tones over 80 hz. Somebody correct me please if I am wrong.
------------------
Maybe my two cents doesn't count, but I am offering it anyway!

so with the distribution of the new software, will the 80hz rule be in full effect?

That would be cool to see the 80hz rule in effect at local comps.That would lower scores considerably I believe...especially in the 1-2 class....JMO!!!!!

but we must not forget that the filter is not a brick wall filter is more inless a annalizer that we red flag when the highest spl is over 80hz correct
this is for wayne
well lets say that a preson system is right at 70 hz ok and his 2nd harmonic comes in at 140hz and the cabin of the vechile is tuned to 140hz and the 2nd harmonic is producing a greater spl how is that gonna work just woundering thanks

I am dont know Db Drag rules and what not like I do USAC. But isnt is true you have to use the Db Jams CD? And if I remember from the one show I did compete in this year isnt that CD like have no tracks that are above 80hz? So if someone is using something other then that CD that I was told we had to use or is getting freq above what is on that CD..That would mean that another source is producing the sound correct? And wouldnt that be ground for DQing?
Either way I think Db Drag Finals will be a great time. I hope I get to meet someone of the people from the forum....

I trust Wayne, BUT I want proof too....
I under stand wht Wayne said....
I also have seen a few Teams still competing with high notes too....

I think If you play a high note you should put on a skirt. Because that is the biggest bitch thing to do. I mean that is the easiest way to get a high reading. I mean comeone who wants 12 15's playing a 180hz note. Someone that will be wearing a skirt thats who.

A lot of the people that have still been playing high notes are doing so just to have high impressive scores to post up on the board...
I doubt they will waste their time at fianls if it won't work... http://www.termpro.com/ubb/smile.gif
Hey Wayne, You need to sell that software to all of the other organizations! hehe http://www.termpro.com/ubb/wink.gif

What kind of punishment would it be if I had to wear a skirt? http://www.termpro.com/ubb/smile.gif And if I do does that mean that I play tones over 80 hz....I think not....LOL....just playing with you guys..I know what you mean.

Hey DQ we all know that you are the Queen of that outlaw 150hz stuff!! http://www.termpro.com/ubb/smile.gifJust messin with ya..... http://www.termpro.com/ubb/redface.gif It definately needs to be made a point at Finals that you will be DQ'd if you are using a tone over 80hz.Not sure if anyone will try it,but who knows???Also is the filter in place for the Deatmatch as well???

the db jams cd does have many freqs above 80 hz. they are not sine waves. the notes are mostly on track two. they might not be of much use to anyone but they are on the cd in music tracks.
Wayne thanks for the reply!

I thought this competion was setup to see who could be the loudest. Not who can do a 70 that noone can hear but a Dog. Also does anyone else think that when they hear these high note cars burp, it sounds like a Tard asking for something. AAAAUUUUGGGHHH

I'm out, that's bout all I have to say.....to the millions of my fans. PEACE

It's about one of the most annoying sounds in my life I think I have ever heard. I mean I went down to Nashville w/ the intention of sitting in the worlds loudest vehicles. Instead I heard the most annoying sounding vehicles, (including a champion). They should of put them in the class of "How retarded can I make 15's sound" class.

lol I agree with that mmatsman....I heard the bronco at a show when it was compeating and it was sicking. But then I also head it in demo mode at 42hz...WOW...
But it dont have to look or sound good to be loud....

I saw a van play a 82hz Note at a show and the Screen on the puter turned Red. So i know that it can be detected. It was at Terry Jacksons Show and the run was DQed!

You guys are overlooking the point of trying to find a car that will have a res freq of over 80Hz. the Panda is like 78-79 and look how small it is! Unless you wall off a Panda it won't do you much good.
Tuning to peak at the natural res freq is still the best way to get loud.
