NOISE RESTRICTION......oooh eeeerr hope my s7 will be ok

[Guest Tim Norman]

Last year the noise limit was 105db at 500mm at 45 deg.

[Guest rizla]

this may be a silly question but how loud is 105db

[Guest Daren.F]

Its halfway between 104db and 106db. Glad to be of help

[Guest rizla]

many thanx

[Guest TerryBarry]

Yes you might think so

Here is a list of decibel levels ( I pinched from somewhere else)

Near total silence - 0 dB

A whisper - 15 dB

Normal conversation - 60 dB

A lawnmower - 90 dB

A car horn - 110 dB

A rock concert or a jet engine - 120 dB

A gunshot or firecracker - 140 dB

 

And the level drops off with distance from the source

 

Two sound sources of 60dB heard at the same time will result in a level of 63 dB

 

HTH

well as long as i dont turn up in a plane and sound my horn i should be ok then

Amongst all this wonderful work that Roberto at RS Jigtec is doing on your Vehicle, is he not fitting a 'new' exhaust & silencer? (if not, it's about the only thing he's not!) if he is, then surely he will guarantee that it will come below the required maximum limit?

Unfortunately if you are relying on the RHSC excuse for a silencer, then I am afraid that Tim & his 'BOB' will win by default! as you won't be allowed on the tarmac.

 

Ah! it's all right Andy! I've trolled throught the 3 million posts that you've made about this flippin' refit, and found it at number 11 on the hit parade, some 4" drain pipe and silencer, lets hope that he puts some stuffing in there!

no jim he is making a custom made 3 to 4inch bore downpipe and silencer,angled away from the rear arch as it will spit flames just not sure how quiet it will be

[Big Jim]

Not much use if it's not quiet enough!!

 

You could get one that's quiet enough though!

[Guest rizla]

should be ok,but im sure it will be a differnt sound than what i had before,hmmmm is the test for noise done at idle or at revs,i think that will make a large differance

[Big Jim]

The test for noise is supposed to be done at 2/3 max revs. at an angle of 45º from the outlet, and ½ metre away from the outlet.

 

Will it? or won't it? that is the question?????????

[Guest rizla]

there may be alot of posts jim,but if you look at most of the topics ive started they do seem to stir the masses(and another reason is im bored without my car) :boohoo:
