IMPBA noise rule & dB meters

[AWaddle322]

Mikey,

It is not Evansville job to send meters anywere and Have them tested at this point. I am certainly not suggesting that Evansville ar anyone else has done anything wrong. I personnally dont care if Equi db meter was on a tripod or not If the DB were side by side and pointed in the same direction how would a tripod alter the readings? the difference in 1 to 2 db ie enough to dq someone so there should be no variance between the meters. The difference between 1 to 7 db is huge, not even in the same ball park huge.

Mr Bendict had a tuff job at the nats ( i sure would not have wanted it). There is no reason for this to be a tuff job though. its cut and dry as soon as the meter issue is resolved.

I will also add that I highly doubt that anything that you buy at radio shack is going to be accurate enough to appease this rule. I have never bought anything from radio shack that worked they way it was supposed to and lasted any length of time. In Mr Bendict case if had a good meter and it was calabrated correctly there would not even be this discusion ( time will only tell if he did have a good meter that was calabrated correctly). What this hole thing to me is about is the wide range 4 meter showed (so what if they are not on a tripod, Does a tripod applify sound) also the rule states that it is highly recommended for it to be on a tripod not a necesatity. Mikey, please explain if the meter that were hand held we not being used correctly (had hand over front plate, pointed in wrong dirrection) because i really dont get why you keep saying something about a tripod!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Not picking on anyone. O and I still believe that the noise rule is a good thing but I am trying to point out the bugs that need to be worked out.

Sincerely,

Allen Waddle

Mikey,

After rereading your post are you implying that John equi was inbetween the meter and the boat on the course?

NO ALLEN BUT I STOOD BY THE METER WHEN I COULD AND FOUND THAT IF YOU STOOD BESIDE THE METER IT SLIGHTLY CHANGED THE READING. I KNOW THE METER IS SUPOSED TO READ STRAIGHT OUT BUT STANDING BESIDE IT OR HOLDING IT IN YOUR HAND WOULD CHANGE ITS READINGS... I HOPE WE FIND A BETTER WAY TO POLICE THIS CONCERN IM SURE SOME HOW SOME WAY TOGETHER WE CAN FIX IT. MY CONCERN FOR NOISE IS THE NOISE IN THE PIT I PERSONALLY DONT CARE ABOUT LAKE NOISE,MY EARS ARE IN THE PITS.....I STILL REMEMBER 2002 WHEN DOC FIRED HIS TWIN K90 BOAT SOUNDED LIKE A TOP FUEL CAR GETTING READY TO LAUNCH. I THINK THE NOISE ISSUE IS REAL AND WE NEED TO CURE IT IN A WAY THAT DONT HURT OUR HOBBY I WANT MY METER CKECKED FOR PEACE OF MIND, ID HATE TO FIND OUT I RELIED ON A BAD RULE AND A BAD METER MAYBE WE SHOULD BACKUP TO 95 DB TILL WE FIND AND ANSWER BUT I THINK ALL CLUBS SHOULD BE CHECKING NOISE AND REPORT TO DISTRICT DIRECTORS THERE DIFFICULTY IN LOWERING DB UNTIL WE AS A GROUP AGREE ON SOMETHING ELSE WE ARE STUCK SO ITS TIME FOR SOMEONE TO PROPOSE SOMETHING WE ALL CAN LIVE WITH UNTIL WE GET A REAL FIX.........;PS I NEVER BOUGHT ANYTHING FROM RADIO SHACK THAT WAS ANYGOOD TRY SOME OF THEIR BATTERIES IN A 1-2 k BOAT I THINK NOT.......MIKE

 

[AWaddle322]

Mikey, The really funny part about the whole thing is after 2 nats in evansville someone has came by at night and said that they were so sick of hearing watch your lanes. Neighbors to the pond complain about the pa system not the boats. I know if the boats were quiter we could quiten the pa down but in reality it takes a ceratin amount of pa noise for people on the other end of the pond to hear what you are saying. Speaking of docs twin the noise used to be really obnoxious but the oil they put in there fuel was the worst it put out a cloud through out the pits that you could not see through or breath in. LOL

Noise cancellation is a fact but only by electronic!

Db is a measurement of amplitude! not frequency! correct?

steve

I watched one heat of sport forty at the nat's that NOBODY, and i mean NOBODY was watching the meter.. i stood there the WHOLE TIME.. not a sole UNFORTUNELY THE GUY MANNING THE METER SON RUNS SPORT40 GUESS YOU MISSED HIM WHEN HE WENT TO THE HEAD ALSO.....WE DONT HAVE COVERAGE TO PUT 2 PEOPLE IN EVERY JOB BUT DID THE BEST WE COULD AND STAND BY IT

Mikey,

I am not trying to pic on anyone.. My point is if it was such a HOT BUTTON ISSUE all week then i would have made DARN sure that there was a body there each and every race.. because of this reason i pointed out.. if you have a rule. and is such a questionable rule to begin with. i would make sure that everyone is looked at..

If i was racing sport fourty's and i wasn't in that race i would have questioned why it wasn't being checked.. see where i am comming from...

this hole conversation about db's tell's me either it is WAY WAY OFF track.. OR WE HAVE A BIG PROBLEM AND NOBODY HAS A VIABLE AWNSER..

oh well gotta love this hobby.

In all honesty this issue sounds more like an issue based around the ideas of principal in most peoples eyes.

It looks like the Evansville club is taking the brunt of the criticism because they layed down the law. What other race sites and events prior to this event didn't follow through and check boats? Those are the people that need to be blamed. It's true, that some ponds tend to be louder. It's true that a boat can be louder at a different pond as well. Until you have run at every race site, you can't assume that your boat is legal. It's all a part of getting passed the so called "Tech Inspection"...

After reading all this crap over the past couple years, I realize that with you guys its more about being at the limit and raged edge at all times. Instead of saying, hey - I am going to run "Muffler X" and tune my boat to that - no you all seem to worry about tuning your muffler to your boat so that you are at 92db and no less. Manufacturers are doing the same. Guys out on the West Coast, IE: Lenny Blake have been making mufflers that have kept boats legal within NAMBA for years - why not run those?

This is a new rule for you IMPBA guys and it takes time to get adjusted to.

What you guys fail to see is that the new DB Rule is actually working. The self-discipline rule of running a muffling type device that was previously in place obviously was a huge disaster, look at what has happened at one of the first big Nitro Events in which people came from all over the country with a DB limit in place...

Congratulations to the Evansville Club for running another fine event. I was able to attend the 2002 Internats and it is still one of the finest races I have ever been to.

Mikey, you guys shouldn't have to explain yourselves. Rules are rules. My hat is off to you and your club for having the balls to lay down the first actions and foundation for finally making DB levels a concern and following the rules.

 

[My Gypsy]

If I am not mistaken, all of the Evansville club members voted against this rule because no one was confident in the proposed method of measuring the db level.

Don,

There is no such thing as cancelling effect of noise. What was seen at the nats with john browns single and his twin is realitevly easy to explain. His twin motors are not working as hard and or not reaching the rpm that his single is. Noise does not cancel out. Here is you a really easy test to test this. Put your favorite cd in your cd player(2 speaker system) using the mono setting. record your dbs and then simply unhook 1 speaker. There will be a three db drop. This is a known fact, not a theory.

Mikey,

Dont ever say one pipe will not work. There are ways to quiten anything down. Until such a time that it is proven that evansville db meters were given the correct db reading all of this becomes null and void. The real bad part part about all of this The IMPBA membership was given information concerning noise with information given using John equi's meter through the roostertail. what should really happen is the noise thing be put on hold or back to the way it was until the IMPBA memebership can get accurate information. What this really means is up until a time that we have a trust worthy instrutment for measuring noise we are all left in the dark. Evansville meter could be reading 94 dbs and for all we really know that 94 could actually be 104. O and one more thing sonce the noise rule is about quiting down the noise on the pond then why did we remove the part about all boats must have mufflers, when this was done all that happened is we allowed smaller boats to get louder, kinda seems against the goal to me .what about you?

Impba Board,

We the people of this orginzation need information quickly, we need to know if Evnasville meter was reading correctly or 10 db high or 10 db low, we have the second half of the racing to go this year and we need to know were there meters stand so that those that were to loud can get in compliance or dtermine that we are already in complaince. We need to be testing know and up intil the time we recieve this information testing is useless.

Sincerely,

Allen waddle

Allen,

Yes there is such a thing as noise cancellation and there is the physics to prove it as well as the anecdotal evidence so far provided. Actually it is known as PHASE CANCELLATION

See the following for an explanation.

I think this forum is a great place to find answers,we will with the help from our forgeign friends and NAMBA friends find the answer. Im sure nieghbors complained about our pa but as you all know we tried all week to give boaters a headsup on upcoming heats. We could have said heat number 4 is on deck and shut up but wanted to and as part of hurring along the race we called names numbers and yelled for Joe Blow to come Pit for his DADDY all week. In the end we still have the 92db rule and must find the answer to make all boats conform. The Nats holds a special place in my heart and should for all boaters,it brings boaters from far and wide to race,enjoy meeting new and old friends and crown CHAMPIONS. At the same time the rest of us also rans can challenge ourselves to be the best we can be. I think its Margrita time but the mixer is too loud so guess i better get a drink of water......GOOD LUCK TO ALL BOATERS ....Mike PS i just bought a 60 mono and may need some help making it meet the rule

 

[Brad Christy]

Guys,

I am in no way blaming the Evansville guys for this, but here is what I see as the problem:

There were (if I count correctly) four SPL meters in place, giving four different readings, and not always in the same perspective (meaning one would dispay the highest reading at one moment, and not so at some other time), indicating that the measurement method was flawed at best. I am greatly disappointed in the IMPBA upper management present for not stepping forward and appointing ONE SPL meter (the one most often reading the lowest) and ignoring the rest of them. If you don't have repeatability, you don't have measurability, and you can no longer "Lay down the law" with any fairness. Whoever it was that put the club guys' to the task of enforcing this rule should have stepped up and revised the process. Again, I don't blame th Evansville guys, but rather the "powers that be" for insisting on enforcing a rule without any reliable means of determining infraction.

Also, I am in no way opposed to any noise rule. I've personally seen many boats run quite well while also running very quietly. Mike Stutzman's F-Hydro at the Celina, OH race was virtually silent and it was running with the pack. I intend to do what I can to make my boats run as quietly as possible, so as to not get caught by this.

Thanks. Brad.

WELL BRAD YOU HAD TO BE THER AND SEE WHAT WAS GOING ON,2 METERS IN PLACE ALL DAY. 1-2 DB APART. AFTER MOST RACING WAS OVER I WAS TOLD JOHN TOOK HIS OVER AND CHECKED READINGS ALONG WITH SOMEONE ELSE. IVE ASKED BUDDY WHO WAS RUNNING THE METER WAHT WAS GOING ON AND HE SAID THER CHECKS WERE NOT VALID CHECKS. WE CAN GO ON AND ON BUT UNTIL WE FIND A FOOLPROOF METHOD MY THINKING IS A CHEAP 50 DOLLAR METER IS NOT THE ANSWER AND UNTIL WE FIND SOMETHING BETTER WE SHOULD GET SOMEONE TO PROPOSE GOING BACK TO 95 DB

 

[Mike Larson]

A little novice perspective, if I may.... And, with the utmost respect to all the big guns on this topic...........The plane guys(some) run 4 strokes hence allieviating the noise issues... we cant...... And in my opinion you will not be able to quiet a 2 stroke down to the level that makes John Q public happy....... The real deal being is, those guys are having too much fun, Im not, so, ill *****...... You men can quiet all you want 92 this year 88 next, the limit will keep reducing because someone will always have to ***** or they wont be happy... England? thats great... anybody wanna front me the money to install Marles pipes on the 11 boats I have? Whatever... Mike Z is right... Electric in the future...... I can see the forest through the trees..... We lost an awesome buggy track here too a while back... put the LHS on the rocks, he had a major investment and got rocked by a group of people saw too many other people enjoying the sport as a whole..... Done deal.... Now... I quieted my piped tunnels the year before the limit was 95 during my winter building..... at the time there were a coupla guys selling add on mufflers... I bit the bullet being the noise concientious person I was and bought a few,,, ( Ill be ready when the 95 db vote goes through) Went to 92..... Ok, I slowly aquired "quiet" pipes for all my boats... retested, still testing, guaranteed, Ive a few aint gonna make it.... Now what? Id like to know, how, I am to silence my stuff further.......Ive got cowled boats, rubber isolaters, stingers, add ons... you name it.... this is almost a moot point with me, I didnt race last year, and probably wont this year... But.... all the people reading would like to know... before they get DQ'd, techniques/equipment to use to gain the reduction the public is calling for....... Another post relevant to this effect would be great! Chris hit it... Show me a pipe..... who sells it? ( I have a vast selection of quiet pipes to choose from, and theyre all noisy) I live and breathe RC boats... theyre my thing at this point.... guess I should build a savings account each year to install the latest quiet technology on all my hulls? How, are the control line guys doing it? Anybody? With the exhaust coming straight outta the port on a 2 stroke in a sound chamber designed to actually force the wave, or a part of said wave back into the port... how come we're still so loud? Pipe design? What? Show me! I impart a lot of funds to doing something i enjoy... most cannot... The average Tommy toenails will not buy, or even try, to invest the time/money into makin a legal race boat, he'll drop ole betsy in wherever he can get away with it, until somebody *******,... then move to a new place.... you cant stop the public from complaining about anything, if, it hits them wrong.. youre done... Anybody DB a Miss vegas outta the box for the hell of it? The hobby store boats are loud, how loud? Gauranteed there are more of these out there than our numbers combined.... I aint picking on these people at all, but, a boats a boat....... And, it makes noise... Somebody will *****, because someone else is having fun..... Dont know. The nats was a big letdown for me, ( bench racer i am) Granted 4% is great, with the controversy its had, you guys will lose members and the hurt is already in place........ Ill not be traveling 400 miles to come to the realization my boat/pipe combination is just to loud for someone to handle for a day..... The meters there were still meters, ( Buddy.. you got a set, man.) the rules is the rules, you cats gotta catch that this is America, and, if you offend someone nowdays, and ***** they will, youre done.... This boating thing is a dog on a leash, runnin..... till it hits the end.... get it? Hate to be a defeatist, but, its there.... We are a very small minority trying to desguise a sport we enjoy, until the majority rips our heads off..... Quiet? My boats are as quiet as I can make them..... to this point...... Id appeciate the sharing of ideas on here on quieter, until the public decides for me.... Relevant to this post? hopefully. Im just a small potatoes boater trying to keep the world happy, so, you guys fight it out, Ill be around Mike

...UNTIL WE FIND SOMETHING BETTER WE SHOULD GET SOMEONE TO PROPOSE GOING BACK TO 95 DB

This would be a slap in the face to all who have made positive steps toward quieting their boats, or already had quiet boats, and a reward to those who have done nothing. :angry: It's been said before, one sure way to be safe is to aim for less than 92.

 

[Bart Drieghe]

Mike , by no intention to piss you off , i reply on your post :

You men can quiet all you want 92 this year 88 next, the limit will keep reducing because someone will always have to ***** or they wont be happy...

True

Chris hit it... Show me a pipe..... who sells it?

For the so maniest time , DB's do NOT come only off the pipe but again like mentioned before , every US pipe i have seen went TOO loud . CMB's nitro pipe ( no idea if they still make those ) was TOO loud .

I have a vast selection of quiet pipes to choose from, and theyre all noisy)

Everybody can name his pipe QUIET , some might even name it VERY QUIET , so what , its not in the name .

The average Tommy toenails will not buy, or even try, to invest the time/money into makin a legal race boat, he'll drop ole betsy in wherever he can get away with it, until somebody *******,...

The average tommy won't be racing then , too bad for him . Simply don't allow him in the club .Its as simple as that .

........ Ill not be traveling 400 miles to come to the realization my boat/pipe combination is just to loud for someone to handle for a day.....

Thats why you guys need 1 rule and not 100 rules. Too many differences( in DB ) will lead to discussions , keep it simple , one rule for everyone .

This boating thing is a dog on a leash, runnin..... till it hits the end.... get it?

Even a several year old dog can be teached new things , you just have to be willing to put the time into it .

Now some remarks :

Several DB meters , okay , right .Nice idea but you'll have to rely on 1 at the end . Try to measure with several speedguns , its the same issue .

Mikey's remark on the tripod is indeed true as i have noticed it before , again , 1 spot( for the WHOLE RACE ) , 1 meter( calibrated )

Don's F remark

I still think the on the beach bench test is the way to go. If we can come up with a number that equates to 92dB @ 50 feet on the water then all this gets real easy. Hmmm, weren't you the first one to mention that approach here.........

I wished it was possible Don but the prop makes a noise too , I've seen it first hand with an offshore boat , the guy just changed the prop and his boat made a different noise .

Mikey's remark

I think part of the problem is some boater objective is 92db when they should be striving for more like 88-90 to be sure to be legal. We have seen pipes that are quiet and pipes that wont work,its time to look for answers to the problem not disect the noise issue as its not going away

Amen to this reply , its simply the truth . 92 DB aint the limit as there are other countries that go WAY lower than that so its no rocket science . IF you get your boat more quiet than it should be , well thats not a bad thing is it? or do you think that the louder the boat is , the faster it is ? Think again .

Tip : Use bulkheads , it makes the boat stiffer but the hull itself will be less resonating too :

http://www.iansboats.co.uk/griff%20float%20mount.JPG

Making your boat silent doesn't mean it will cost you loads of money , its just a different way than you have been used to make your boats .

I can understand that some people do not like the rule but the actual rule should be very achievable for every racer . Indycar , Nascar , Formula 1 , they all make new rules , don't like them ? well Sorry for you but you won't be racing than . As simple as that .

Getting your boats quiet ( or more quiet ) is an investment , not only money wise but in time too . For your health , your buddies health , your family , your neighbours .

Concerning the DQ , i'd be a bit more careful on that matter and use 2006 as a "testing year " concerning the DB's . A : the impa has to learn how to work with the rule(s) , B : the Racesites /organisers have to learn to work with the rules , C : the drivers and their boats .

Its not an easy issue , i completely agree on that part but its not a bad rule .

Best Regards ,

Bart

Ya'll are giving me a headache and running new boaters off by the droves. Why would anybody want to jump into the middle of this crap. :angry:

I totally agree. To reverse course now would, in my thinking, open the opportunity to losing even more lakes to noise issues. At least we can say that there has been a positve move to quiet the boats down. May have flaws with it now but the noise levels have come down and that cannot be disputed. If our European brothers can do it - 80 db guys and not 92 that many are squawking so hard about, so can we. Let's get to work and get it done. ENOUGH!

 

[Scott Norris]

I'll be honest with all of you. There are clubs running on ponds that are in city parks that are going to have to adhere to these rules. There are clubs that are out in the boonies that wouldn't bother anyone if they were running pulse jet engines. This isn't going to work and it's going to run off future boat racers by the hundreds. It will be enforced at some sites and won't be enforced at other sites. The Internats are going to become a hinderance rather than bragging rites for clubs to host. I can see that happening as Mike Shindler is having to defend his club rather than saying thanks for all the congrats. If this is the way it's going to be I'll just go frigging race cars or just sell all my stuff and say screw it.

I'm tired of this noise crap. The Nitro Funny Car Drivers don't have to listen to this.

I run quiet pipes on all of my boats and every time I go to a race I can't hear my boats to tune them unless I am out there by myself!

 

[Piston1]

SO FAR NOBODY HAS A VIABLE ANSWER. I SAY BACK TO 95 UNTIL WE GET A VIABLE ANSWER.

 

[piper_chuck]

SO FAR NOBODY HAS A VIABLE ANSWER. I SAY BACK TO 95 UNTIL WE GET A VIABLE ANSWER.

Much of the rest of the world seems to have "a viable answer", why is it so damn hard for some in the US to figure it out?

 

[Piston1]

I always voted againt it. It should be handled at a local level in accordance with local regulations and any credible guidance that the sanctioning body could offer. It should be noted that 92db is in violation of most if not all local noise regulations.

Tired of this noise crap???

Its called keeping lakes to run on.... Sorry if it is inconvenient for you...

If you like we can have a different limit on each lake depending on how close to residential areas it is... and to be fair at the lakes in the middle of nowhere why dont we have a MINIMUM noise level requirement????

If there is an IMPBA limit on noise then it WILL BE ENFORCED at ALL LAKES. And in future you will hear your boats better because all the louder boats will be taken off the water... You should be happy knowing you have already done the work on running quieter and your competition will have to catch up to you..

As with most rules in their infancy they will be tested, disputed and debated. Eventually they will become as second nature as 'thou shalt not cut buoys'.... Just relax and work with the system rather than against it... There is bound to be a few bumps along the way... All the boaters here that support noise limitations are not doing it to spoil other people's fun. They are supporting it because they know that without these limitations we stand to lose more places to run our boats. This may not impact some people directly but it is for the good of the sport as a whole.

People do argue that some clown outside the clubs can throw their 100db boat on the water and spoil it for the others anyway but with a National Association supporting the local club with realistic noise limitations applying it actually works in favour of the club because they can actually argue for more control over the lake to stop the noisy 'non club' boats running there.

"This isn't going to work and it's going to run off future boat racers by the hundreds."

How many boaters will you lose if you have no water to run on???
