IMPBA noise rule & dB meters

[teddyd]

HI MARK,

THAT STATEMENT WAS RIGHT FROM THE HEART, I FEEL YOU. I'VE BEEN IN THE RECORDING ALL MY LIFE.

I DEAL WITH SOUND EVERYDAY, WHEN IT COME TO SOUND, REFLECTIONS CAN BE COME A MONSTER.

WHEN YOU GET SOUND REFLECTIONS BOUNCING OFF EACH OTHER THE SOUND GET OUT OF CONTROL.

I SPENT $4000.00 TUNING MY STUDIO CONTROL ROOM TO GET RID OF THE REFLECTIONS SO WHAT WE WERE HEARING WAS WHAT WE WERE GETTING ON PLAYBACK. WE HAVE A SWEET SPOT IN OUR CONTROL ROOM WHERE EVERYONE WANTS TO SIT BECAUSE THE MUSIC SOUND BETTER IN THAT SPOT.WHEN SOUND WAVES ARE POSITIVE AND THE REFLECTIONS ARE NEGATIVE THAT A BIG PROBLEM, YOU GET WAVE CANCELLATION.

I KNOW WE'VE GOT TO DO SOMETHING ABOUT THE NOISE DB, BUT THROWING OUT A NUMBER THAT GOING TO WORK AT EVERY RACE SITE IS NOT GOING TO WORK. MOST OF THE PEOPLE THAT'S READING THE DB METERS ARE NOT QUALIFIED TO DO SO AND THEY HAVE THE POWER TO DQ A BOAT? I DON'T SEE NO WAY TO COME WITH A HARD NUMBER THAT WE CAN JUST SAY THIS IS IT. THE EVIRONMENT FROM RACE SITE TO RACE SITE IS TOTALLY DIFFERANCE. SOME SITES HAVE TREES , SOME HAVE ROCKS,

AND YOU ALSO HAVE THE TRAILERS, SPECTATORS AND THE TENTS PLACMENT. ALL OF THESE THING HAVE A BIG EFFECT ON SOUND. MAYBE WE NEED A DB FOR UP TO 7.5 AND A DB FOR 67 AND UP.

I LIVE IN A NEW SUB RIGHT NEXT I-75, 3 YEARS AGO THE STATE INSTALL A 3 MILLION DOLLAR SOUND RETAINING WALL, SOMEDAYS YOU CAN HARDLY HEAR THE TRAFFIC AND OTHER

DAYS IT'S LOUD AS HECK. ALL I'M SAYING IS, WHEN PLAY WITH SOUND PRESSURES, WE NEED SOMEONE

THAT KNOW THE TECH SIDE OF IT IF WE'RE GOING TO DQ BOATS.

Well, I disagree Teddy. Loud Noise is Loud Noise, no matter if you are a child , an adult, a Ph.D or a high school dropout. When boats are too loud, everyone at the race knows it, without a db meter. It doesn't take a tech guy to DQ a loud boat. It doesn't matter if the local site has something to do with it. The noise that gets to a persons ears is the sound the db meter picks up too. That is the way it is. The rules as written are consistent with this philosophy. I think that what needs to be decided is , is this the philosophy we want?

If not, we better change it.

Now with all of this said. I am running a committe to fix this problem and the people that I have ask are good people. And we will fix this problem. Why because I believe in IMPBA and I do believe in making boating stronger.

Mark Bullard

District 5 Director

And we will fix this. Mark, you & I should touch base again on this soon as I will have some updated info on recent tests in the next week or so.

I started writing this post with an angry tone, then I deleted it and rewrote it.

What you said about the meeting is not true I never laughed at your proposal. In fact I stated that if anyone could get us closer to a solution it was you. And the retireive boat thing I was not present to see that happen you must be thinking of someone else.

As far as testing well I am not sure but I have never seen you at the pond here in Minnesota. I am not as educated in these areas as you but I can test ideas and that is what I am doing. Attaching me on a public forum in uncalled for.

I wish you and your commitee well in fixing this problem and look forward to seeing a proposal in the future.

Oh by the way I run boats from 90 riggers on down to .21 tunnels

Mr. Nelsen, with all due respect state your points. I am sorry to say that you have been rambling all day long privately and publicly. What exactly is what IMPBA is doing to resolve this problem. The membership demands to know.

Ask Mark he the head of the committee working on the problem.

I have stated what I am doing sorry if thats not enough

Iwill now just watch and read as commenting is a bad idea.

Jose' have you appointed yourself spokesperson for the entire membership as I see no "demands" except from you. Come on now let's be real here.... :blink:

 

[Piston1]

You have stated nothing so far. I privately told you my view on this issue and all I have heard from you is that you have some research in progress. Perhaps you can share some of it so that we can provide some constructive comments.

Well no offense but when will your comments start being constructive? I've stated plenty, it's just nothing you in particular feel like hearing. From my take of your posts you'll only be happy with repealing the current rule as you keep saying to do so, which I don't agree with......... :blink:

HI BRIAN S,

WHAT I WAS SAYING, IF YOU ARE GOING TO DQ A BOAT MAKE SURE YOU ARE NOT WRONG.

JUST BECAUSE ONE BOAT SOUNDS LOUDER TO YOU THEN THE NEXT BOAT DO NOT MEAN THE

THE LOUDER SOUNDING BOAT IS ACTUALLY LOUD, YOU ARE GOING BY THE SEAT OF PANTS NOW.

LET GIVE YOU AN EXAMPLE WHEN YOU ARE NOT TECHNICAL AND FLY BY THE SEAT OF THE PANTS:

JUST BECAUSE A BOAT LOOKS FASTER DO NOT MEAN IT RUNNIG LOWER LAPS TIMES, PUT A STOP

WATCH ON IT AND THE SLOWER LOOKING BOAT MAYBE ACTUALLY BE FASTER. RIGHT OR WRONG?

I'M SAYING IF WE'RE GOING TO DQ BOATS FOR NOISE, LET'S MAKE SURE WE ARE NOT WRONG, YOU CAN'T UNDO THAT. CAN YOU LISTEN TO BOAT AND TELL US THE ACTUAL DB'S BECAUSE IT SOUNDS LOUD ? CAN YOU LISTEN TO BOAT A AND THEN LISTEN TO BOAT B AND TELL HOW US HOW MANY DB'S DIFFERANCE THERE WAS BETWEEN THE TWO?

........TEDDY

 

[Piston1]

Don, no offense taken.

I know we're all wrapped up in a debate about sound meters, decibels, etc, but isn't the bottom line how the boats sound to the human ear? After all, the people complaining about the noise generated by our hobby aren't sitting there with a db meter, it's their ears we're bothering. If a boat sounds quieter to us, it'll probably sound quieter to the neighbors too.

During open water at our last race there were a couple boats that "sounded" louder than the rest. Was it just coincidence that the db meter confirmed it? Nope, didn't think so. At races, people know which boats are loud, the meter's just being used to quantify it.

It's really unfortunate that some people are working so hard to repeal, or at least temporarily suspend, the rule we recently approved. It sure would be great if this energy were invested in making boats quieter rather than trying to put off the inevitable.

ALL I CAN SAY IS, IF SOME OF YOU GUYS WERE JUDGES, THERE WOULD BE A LOT MORE PEOPLE IN JAIL BECAUSE OF YOUR BELIEF!!!! :lol: h34r:

The goal of this rule change was to lower the overall sound of racing. WE ALL know that some people have embraced this goal more than others. Those who are being dragged, kicking and screaming, toward quieter boats are really not helping the overall health of the hobby, at least not wrt preserving sites. We need to reduce sound and arguments about measurements are in a way a distraction. Heck, I tried to keep my boats quiet 20 years ago.

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:

Steve I wish you could have been there @ the 2006 IMPBA nats. I seen your boats run @ Huntsville. You would have been DQ`ed.... I had to change every muffler I ran @ Huntsville Spring 2006 race. Many stk parobolic pipes were warned & were wearing rubbber Ex deflectors the next heat...... Some one metioned tapping the stinger & adding a water fitting.. P/S Water pressure exceeds Pipe pressure resulting in Junk engine Brgs quickley.....

 

[EatMyShortsRacing]

If there is any dispute over boats not conforming to the measurement at the time all that needs to happen is COMMON SENSE PREVAILS.... There is two ways to interpret rules - the letter of the law, and the spirit of the law!!! If a boat clearly breaches both of these interpretations then it is off the water...

Joe i was also at the Huntsville spring race,no sound meter in place. You guys think your legal cause you got away with it being loud at races that were lax or did not check db at all just my point

 

[Bob Finn]

The rule may not be perfect, and the enforcement may need to be refined. BUT- You are either part of the problem, or part of the cure. Its not difficult at all to conform to the rule. If you want to.

 

[bzubee]

Joe, the reason you had to change your muffler set up was due to the fact that we had no DB device at the Huntsville spring race since we were even too short on manpower to run the race. 4 workers and 2 part time workers just isn't enough workers to get every thing done.

IF everyone stops and takes a look at who all is doing the complaining it is the racers that do not host races and actually have sites to run at or try to keep. They are the visitors to the other people's race sites that they have worked hard to obtain and keep.
