Remember that noise has killed so.many in this world. Just another cash cow and government investment that a mp or more has shares in a company making the tech gear. Imho.

It doesn't seem obvious how these noise detectors will be able to acertain guilt - what if there are other bikes or even cars in the area at the same time?

I am going to leave my OEM pipes in the loft for now...

I truly believe that changing down a gear as I come up behind cars, to let the dozzzzzzy bu..er know I'm there is whats kept my alive over the past 45 years. Bitza.

dont panic noise is not that easy to measure accurately we use calibrated noise meters at work and they all give different readings ha ha

The noise tests that enable cars and bikes to be road legal are very specific drive-by tests. These could not be accurately replicated by a roadside device somewhere. So we cannot be talking about whether a vehicle is road legal.

What I assume is that someone wants to be able to catch those people whose use of their vehicle and the noise it makes would constitute anti-social behaviour. The problem is what level of noise is deemed to be anti-social?

For noise complaints submitted to councils they are usually looking for a noise level of 10dB(A) above the ambient sound for a prolonged period. However this is measured inside someone’s house, not by the roadside. What level of roadside drive-by noise would be considered to be too loud?

Considering that distance affects the volume of a sound the distance of the offending vehicle from the measuring device would have to be factored in. Also multiple vehicles in close proximity to each other could make quite a loud noise because the sound from each vehicle adds together, but how will the measuring device determine which bit of sound came from which vehicle? It can’t.

So the proposal is utter nonsense until such time as the vast majority of people drive electric vehicles. Then anyone driving something louder than a milk float can be prosecuted for disturbing the peace.

I’m going to get a European passport and **** off to Tuscany ASAP the way this is panning out.

Surely the amount of rain we get in this country would make them an unreliable measurement anyway?

The denser air when it’s raining means they can’t even use the handheld dB meters for noise testing at race meetings and they are only 0.5m away from the exhaust outlet let alone use the trackside ‘ride by’ meters some circuits have installed so a roadside one would almost certainly give questionable readings I would think.

Either way I like the idea of fecking off somewhere away from this country too.
