Owners of cars with noisy exhausts may soon find their vehicles subject to an objective noise test.

Transport Safety Minister Harry Duynhoven says regulations allowing such tests kick in in three weeks. The move has been previously flagged.

He said noise-measuring equipment was coming into the country and would soon be available at nine sites. There would also be one travelling machine.

Noisy cars could be subjected to a test if they were pulled up by police, who would "green-sticker" them. The vehicles would then have to be taken off the road until they passed a test.

At the moment cars undergo a subjective test as part of getting a warrant of fitness.

Mr Duynhoven said the Government intended amending the law so objective tests could be brought into the warrant of fitness testing regime.

I'm picking that cops will be paying a LOT of attention to zorsts in the next few weeks. New brooms and such like.

Yeah, the brainless ones that blarrrgh-pish-blaaaaaaargh-pish right on front of the cop-shop have been ear-marked already.

It's not so much the loudness but WHERE that loudness is used - or at least that's my attitude.

3am on a Tuesday night around town = complaints from householders to me= tickets for the brainless noise dispensers.

My old NSR250SP's dry clutch made more noise than the zorsts.....

With what levels and testing methods will they be using? BSA and some other international standards outline how to correctly test vehicle noise levels, who want to bet a dollar that they are making their own backwards hick method!

Rattly diesels make to much noise as well according to some test done a while back, and what about Jacobs brakes they better be outlawed as well as they aint going to pass no noise limits are they!

We already HAVE the Backwards-Hick method: "That zorst sounds waay too damn loud boy, here's ya ticket".

Warning:
03/07/2006 - Objective noise test. The Minister of Land Transport Safety has announced the introduction of an objective noise test. The test is being rolled out in two stages. Stage one commences 19th July but applies only to entry certification and Police action. Stage one will not apply to WoF so please continue to
use the subjective assessment in the VIRM: In-service Certification. Stage two will include WoF requirements at a later date

This is the flag on the log in page of the WoF site....I wonder what stage two will bring in for the WoF inspection? Maybe ''I think your car/bike sounds too noisy - you have to take it to ***** for an objective noise test,return with documentation and I'll issue your WoF''.

And soon we'll have a subjective smoke test - like,we floor the throttle and have a look out the back....and some old fart who never drives his car more than 2 km fails because his muffler is full of water and produces clouds of steam in cold weather.There'll be a few old Mitsi's and the odd diesel fail,that's about it.

It will be bullshit no question.
Unless they can replicate the OE Manufacturers testing, then heaps of stock vehicles will probably fail too. Most cars/bikes are tested at specific revs in ideal conditions to pass strict Euro tests. I doubt the police or wof people will be doing anything like this.
It'll be done in a noisy warrant building with bare colorsteel cladding (for added sound reflections) and some dumbass tester will be standing closer than specified to the exhaust end with an expensive meter set to the wrong Decibel rating

My old Honda Accord SiR made more noise from its intake than the exhaust....I wonder how they'll get around that.......

Sounds quite fair and reasonable. I am getting to the age where I quite enjoy a bit of sleep now and then.

The test are very specific, will see if i can find them

from the 1976 traffic reg this is what the test used to be and which should still be used!

THE ANSWER- GETTING IT
Bugger, put that last post as a new thread... oh well

To ascertain how this 86dBA is measured you need to follow ISO 362 (practically identical to BS 3425).
There are conditions over 6 pages with all the details but these are the guts of it

-measurements shall be made in a level open area with no reflecting items (buildings, boulders, fences etc) within 50m.
-There shall be a minimum of 20metres square of ashphalt or similar road surface (that has to comply with ISO 10844... I did say it wouldn't be simple!) with a further minimum 10m stretch at either end (at least 3m wide) prior to entering the 20x20 area.
-The microphone is 7.5m away from the centreline in the middle of the 20x20 area
-4 measurements are made per side .. ie vehicle does at least 8 passes
-vehicle must be warmed up first
-As the bike approaches the 20x20m area it must be doing 50km/hr in 2nd and/or 3rd gear (if 5 forward gears or more are fitted). The bike then accelerates hard across the 20m and then the throttle is closed as the rear of the bike passes the 20m line
-if the engine RPM's exceed the maximum net power point, the test is done only in 3rd gear, otherwise both 2nd and 3rd are used
-minimum of 4 consecutive measurements must be done and be within 2 dB

and it goes on and on... (incidentally I do realise I'm the only one interested at this stage!)

anyway... the reason I write all this is because the friendly man at LTSA mentioned that PIGS Ltd. have tried to prosecute some Harley owners with loud pipes. However, as is sadly oh-so-common in the field of acoustics, they didn't know their arse from their elbow and the cases got thrown because the cops didn't seem able to provide evidence as to what the law even was, let alone that the bikes were legitimately tested!
Apparently they tested them in warehouses in an attempt to get louder readings (I imagine they stood behind the bike and revved its arse off to!)

edit : some more http://www.kiwibiker.co.nz/forums/sh...oise+standards

and deano put this up "The 1976 Road Traffic Reg's does contain an objective test to test vehicle noise. It refers to British Standard 3425 or ISO Recommendation R362."

So why is this objective test new? As they overwrote the old law with with fucktard boy racer law before relising they had shot themselves in the foot by using subjective tests rather than objective, law making monkey in parilment will not be getting thier bannanas this time!

And it will be user pays - you will be directed to take your vehicle to the place of inspection (and make an appointment) upon completion of the test you will pay the inspection fee - pass or fail.
