caprinerd Posted June 22, 2009 Report Posted June 22, 2009 can someone tell me what the legal noise level is for a road legal exhaust and at how many revs and also how far from the end of the exhaust have i got to measure from as i ave now got a decible meter and want to find out how loud i am and if its legal
bigdaz27 Posted June 22, 2009 Report Posted June 22, 2009 there is no ligal limit so as loud as you like the police can ownly do you if you rev the whatsits out of the engine in your local mcdonalds car park and some one complanes they could do you for public nuisance or similar
bigdaz27 Posted June 22, 2009 Report Posted June 22, 2009 Noise is not very well covered in the regulations to be honest and its a bit of a grey area...
caprinerd Posted June 22, 2009 Author Report Posted June 22, 2009 okkie dokkie then thanks for the help anyway
NginEEr Posted June 22, 2009 Report Posted June 22, 2009 i believe for reference its 10cm away at a 45 degree angle at 4000rpm... thats for road rallies, on unclosed roads.. not 100% on distance away but the rest is correct
vibrating_Cake Posted June 22, 2009 Report Posted June 22, 2009 NEW mot rules apparently say if the exhaust is noticeably louder than standard its a fail.... nobody listens to that though, other than that the legal limit is which the policeman seems to be causing a nusance e.g. in estates at night
Copey Posted June 22, 2009 Report Posted June 22, 2009 im sure at sva its 96db thats only for bikes, there is no DB limit for cars
martina Posted June 22, 2009 Report Posted June 22, 2009 It's down the tester if i thought it was to noisy i would fail it, i have only ever failed one car for it and that was a saxo but it was bad.
Fiesta Steve Posted June 22, 2009 Report Posted June 22, 2009 Ok boys and girls this is a quote from 'Daggle' our resident traffic cop, hopefully he won't mind me quoting him Well its taken a bit of searching but here goes once again from the good book The Road Vehicles (Construction and Use) Regulations 1986 regulate the construction, weight and equipment of motor vehicles. Regulation 55 provides for the control of noise made by certain vehicles with three or more wheels. It states: 55(1) This regulation applies to every wheeled motor vehicle having at least three wheels and first used on or after 1st October 1983 So for most of us OSF'ers then the regulations don't apply to motor vehicles made before Oct 1983, however for the capri and fiesta boys then the noise limit must be below 80 decibels, this however can only be tested with a prescribed device
Toby Posted June 22, 2009 Report Posted June 22, 2009 NEW mot rules apparently say if the exhaust is noticeably louder than standard its a fail.... My tester said that and said - I'll let that go as I have no idea how noisey these were 40 years ago - I wasn't even born!
mk14dr Posted June 23, 2009 Report Posted June 23, 2009 When the escRot got VOR'd by VOSA back in december, the young lad that was left to inspect the car was insistant that the exhaust would not pass and MOT, much, much too loud apparently. As I said to him at the time, if you can find me a totally standard mk1 escort, running a NOS exhaust then I will concede and change it. Needless to say, the exhaust stayed, it passed an MOT and has since been changed for something a little quieter for my sanity
Stu_B Posted June 23, 2009 Report Posted June 23, 2009 http://news.bbc.co.uk/1/hi/england/8112905.stm Vehicle noise levels should be between 82 and 89 decibels and background noise between 50 and 60 decibels.
Toby Posted June 23, 2009 Report Posted June 23, 2009 82-89db oops As you say! Ooops - my induction noise is over 100dbs
mk1super Posted June 23, 2009 Report Posted June 23, 2009 82-89db oops As you say! Ooops - my induction noise is over 100dbs That rocks Toby 100dbs of induction noise ooof
Toby Posted June 23, 2009 Report Posted June 23, 2009 82-89db oops As you say! Ooops - my induction noise is over 100dbs That rocks Toby 100dbs of induction noise ooof It not noise
Copey Posted June 23, 2009 Report Posted June 23, 2009 well my exhaust is already over that...and its only set to get louder!
CrazyCharlie Posted June 24, 2009 Report Posted June 24, 2009 im sure at sva its 96db thats only for bikes, there is no DB limit for cars its not just for bikes, my friend has a evo 3 i think, the police stopped him and fined him 30pound for it being to loud, i cant be certian but i think they said it is bout 90-96db
Toby Posted June 24, 2009 Report Posted June 24, 2009 er mines at 111db@4000rpm Quite loud Isn't every 3db's twice as loud? That would make you about 6 times over the limit! I borrowed a noise meter thinking I would run an open header at Brighton speed trials (noise limit 113) and it went off the 130db scale!! I thought it was a bit noisey!
