The latest onslaught against bikers. Acoustic cameras to be tested. Will they work in pinpointing 'offenders'? What about revving, backfiring, horns etc? Rural maybe, but city? Any thoughts?

I've just half heard it on the radio.

https://www.bbc.co.uk/news/uk-48564995

(apologies for BBC link)

So at what point do they differentiate between tyre noise and engine noise?
What if a loud sound is near you and then weeks later you get a ticket and not the louder machine?
Can we have them for aircraft with no silencers please (those little hobby noisy twats) and so on.

And to quote:

'Dr Jonathan Moore, who chairs a campaign group lobbying to reduce noise along the A32 in the South Downs National Park, said people are "thoroughly fed up" with motorcyclists who drive through villages "hundreds of times a year" at anti-social hours.'

That's right folks - motorcycles have a separate rule whereby they're not allowed to be used at certain times of the day/night.
This is stupid government doing stupid stuff. It's all OK though because it brings in revenue.

Loud bikes save lives? But can also see it from the residents perspective if there is anti social behaviour going on.

All seems a bit pointless though when electric vehicles are on the horizon, and combustion is being driven off the road with ULEZ and the like.

Might as well throw in worn diffs on large vehicles while I'm at it. Silent at standstill but noisy when moving.
Bus brakes when reversing only.
Football fans cheering when a goal is scored etc etc.

I like the sound of some loud engines but other people don't. I'm probably in the minority - most people just want stuff to be fairly quiet, And now that I think about it my current bike is nearly as silent as a...well, a ninja. Gets rowdy up around 10k, but under that it just wafts around the place in a pretty refined, subtle way. When I first got it I thought fts, I'll chuck a can on it. But pretty soon I came to appreciate the understated "noise" it makes.

Tbh I'm glad most engines *aren't* loud. Imagine all those cars with shit il4 engines and how bloody crap it would sound if even mrs green's micra made a racket.

Different things annoy different people. 'Boring' meters and bad parenting fines would be ok by me. I'm ok with road noise in the day, in town. Motorcycle racism is an ugly thing though. Met someone the other day who said, 'I don't like motorbikes'. Enough said!

But my point is that the vast majority of people get pissed off by noise. Particularly traffic noise. These aren't just eccentric, subjective whims comparable with morris dancing or dogging.

Do they really, car/van/lorry/bus driver listening to music, rowdy passengers, driver could be deaf, and you have someone relying on loud pipes, when, they should be relying on obs , spatial and road awareness, then that's not a good situation to be in, in fact, there is a risk loud pipes lead to dangerous complacency, because, everybody says "loud pipes save lives"

This I agree with, it'll take at least 5-10 years, if not longer, by which time a high percentage of new vehicles will be electric, and, thus quiet anyhow !!

To be honest as much as I enjoy a noisy can on the right engine when commuting or going for a short hoon the rest of the time I actually appreciate the fact that my bikes are reasonably quiet. I wear ear plugs anyway. The louder cans I've used in the past became grating on a longer run and often made my ears ring, even with earplugs, and most of my runs are full day efforts now.

Outside of motorway filtering I can't say I noticed much difference in driver reactions ahead of me with the loud exhaust.

95% of cars on the road are whisper quiet already, even w/ ICEs. Yes, they will become even quieter if - IF - electrics become predominant. However at this point it's marginal acoustic gains. I'd bet decent money that by far the biggest noise losses have already been achieved in, say, the past decade or two. At this point it's probably road surfaces i.e. tyre noise that're the biggest culprits. Softer compound on smoother, better constructed (i.e. not granite chip dressed) surfaces could well make for greater noise loss than going from a nice, quiet ICE to an electric. Fuck knows - I'm just chucking that out there.

What's the betting these sound cameras also take a recording of speed somehow?

I would imagine you could challenge it and then go to some testing station (after you've put the baffles back in) and have it tested.

The whole thing of the loud pipes blarney is nowt more than a rhetorical justification for making a racket. If you work on the inescapable principle that the more conspicuous a vehicle is (both visually and acoustically), the more obvious its presence will be to other road users and pedestrians - and thus safer - the LPSL mantra amounts to a call for all vehicles to be a fuck of a lot louder. ALL VEHICLES.

But oh no - only bikes should be permitted to be louder because they're more dangerous and their riders correspondingly more vulnerable. Thing is, it's precisely that which makes them so attractive to (most of) the people that ride them. In the most basic sense of the word, we're all adventure seekers. If bikes weren't dangerous, they wouldn't be exciting and rewarding to ride; they wouldn't have the bad-boy "he's a suicidal maniac, I tells ya" image they've acquired. And people wouldn't take exception to them.

It's like the old adage that there's only one thing worse than bad press and that's no press. I swear to fuck, there's a very goodly proportion of dicks at your average bike caf who would despair if "normal" people stopped holding them in contempt. But to hear them bitch and moan about being a regarded as lunatics and thugs you'd think they were the last of the mo-fucking-hicans.

I presume they would have to be linked to cameras to identify the vehicle in question, and even then how do you prove the noise is actually coming from that one vehicle when it's in a row (or 3 rows on a motorway)of vehicles travelling nose to tail.

You get some idiots at bike cafe's. Best avoid them in spunktrumpet season. Most people I know simply don't care what others think of what they ride. I don't care either, up to the point someone is so anti-bike that they're a danger to me.

Any fixed noise detectors will just increase adoption of switchable baffles. The whole demented plot sounds like a NIMBY's wanking material, and will never come to fruition bar a couple of pilot schemes at most.

Just as easily as noise-cancelling on most phones can cut out background noise yet leave your voice crystal clear. A noise trace of an overly-loud exhaust will be easy to identify in software. For prosecution all they'd probably need is the noise trace combined with the actual recording.

I've had to set up noise monitoring on demolition sites where we were subject to strict limits. It's very easy to do, set a limit where if it's exceeded it triggers a recording and takes a noise reading.

On one site in Westminster the monitoring station emailed the weekly triggered events once to the client who immediately put in a complaint about the number of excessive noise events that were getting reported. I downloaded the recordings and they were all police/ambulance sirens Very Happy

I would say it's obvious that noise increases awareness of your presence by other road users, but if you needed an example they're debating installing noise generating turbines in EVs for this very reason. I don't really think its contestible to say otherwise although granted there are mitigating circumstances.

Love loud pipes. Just about to have Stage 1 with short straight through pipes. They will certainly be hear me coming. That's why I ride a Harley, for the crack! My last bike was a 200 mph crotch rocket. That was great too with Yoshi cans. Not sure how they will pinpoint the noisy bike in traffic. Adds to the cat and mouse thrill. Love bikes, fast and a bit noisy.

Loud pipes for the sake of loud pipes? Nah. Certain engines sound nice with a free-flowing exhaust, others (a lot of chavvy cars imo) just sound like wet farts.

And on that, at least a noisy, speeding motorcycle tends to be past and gone quickly, whereas the aforementioned chavmobiles seem to linger on the nerves forever.

But hey, I very much doubt that this will affect me much - all good fun for the next generations; enjoy! Laughing

They're testing it...

And what they'll find is ppl slowing down near the cameras to reduce noise just the same way they do with speed cameras.

The word for today is "sop."

Acoustic cameras in isolated rural areas? That sounds like an expensive operation. I do hope nobody goes out at night with a can of petrol and sets them on fire. That would be terrible! If the equipment is vandalised, it could even mean the plans are abandoned. Terrible!
