Crack team of boffins hash out how e-scooters should sound – but they need your help*

(2022/01/28)


Poll Boffins from UCL's Person-Environment-Activity Research Laboratory (PEARL) have linked arms with London e-scooter providers to decide on a "universal sound" for the silent but deadly transport mode.

It remains illegal in the UK to use a privately owned battery-powered deathtrap, but that hasn't stopped the great unwashed – as anyone who has suddenly had to dive off the path during a parkland walk will tell you.

However, to allow the craze in a regulated environment, rental firms have been popping up all over the country – including TIER, Lime and Dott in London – as evidenced by the amount of scooters cluttering pedestrian walkways or, indeed, the local river.

[1]

But since they are near-enough silent, except for the gentle rolling of the wheels, e-scooters are faced with a similar conundrum to electric car makers – that is, how should they sound for the sake of the safety of people on the street, and particularly those with sight loss.

[2]

[3]

Michael Pfadenhauer, Porche's head of acoustics, [4]summed up the problem thusly :

There is no e-sound. It has to be invented. The sound transports the emotions of a vehicle. It gives you feedback about the potency and capability of the car... At higher speeds in sports mode, a more intense acoustic feedback is needed to make customers experience the potential of the vehicle.

OK, we doubt e-scooters are capable of much over 30mph, if that, but stepping out in front of one is still going to cause a nasty accident. So TIER, Lime, Dott and PEARL, with the blessing of Transport for London, are trying to hash out how the vehicles should sound regardless of operator or make.

[8]Eggheads have crunched the numbers and the results are in: It's not just your dignity you lose with e-scooters, life and limb are in peril, too

The group is consulting with "disability experts and access consultants, including Transport for All, Thomas Pocklington Trust and Royal National Institute of Blind people" and the sound will "take into account the needs of individuals including those with sight loss, hearing loss and neurodiverse conditions."

Professor Nick Tyler, director at UCL PEARL, said: "Through studying how the human hearing system has evolved, we can create sounds for e-scooters that are detectable without adding more noise to the environment. We plan to test a range of combinations of sounds and environments at UCL PEARL with people who are less likely to detect e-scooters nearby, so that we create a sound that works for all. It is a huge scientific challenge, but one that will enable everyone to feel comfortable with this new form of micro-mobility that is quickly growing in popularity."

While PEARL's adherence to the scientific method is admirable, The Register is sure that our readership might have some ideas about how e-scooters should sound. So please cast your votes in the poll below or – even better – suggest your own in the comments. ®

Or just design noisier tyres and let tyre noise do the job?

FeepingCreature

I've been driving my E-Scooter to work for a year. The tires have lost all profile, and since they're solid rubber they're not easily swappable.

Tom 7

Sounds like they're not road legal then.

Anonymous Coward

In the UK, private e-scooters aren't road legal no matter what state their tyres are in. They can only be legally used on private land.

Tom 7

I take it the Met are in charge of prosecuting them then.

adam 40

They are slightly less illegal if you paint yours in the colours of the local hire company....

So… no motorways, huh?

ReallyEvilCanine

There goes my cunning plan to use the M25 as something other than a carpark.

Anonymous Coward

That's what I though. Just mandate square tyres and be done with it.

Certainly something with the wheels

ReallyEvilCanine

Like a playing card in the wheel spokes… or digital reproduction changing speed/pitch based on the scooter's speed.

I felt like Dan Aykroyd's character in Ghostbusters, in the scene when it's time to "choose the form of the destructor": "I couldn't help it, it just popped in there."

Why did they not list the only obvious choice?

Skiron

What they need to do is get the bloody things to only do a max speed of, say, 10MPH. Some I see must hit > 20MPH on the PAVEMENT!

Halfmad

I'm more worried about us not having any strategy for recycling them, other than landfill.

should be illegal to use until this is in place and ideally owners pay.

Skiron

"...actions of the pedestrian when he give you an upper cut".

There, FTFY.

It rings a bell

maffski

So, how to alert people to a small two wheeled personal transport that moves silently through mixed use spaces?

I can't imagine anyone has ever had to solve that problem.

Re: It rings a bell

Arty Effem

A pavement is not a mixed-use space.

Preach.

You on a recreational means of motion? Take it to the streets.

Awww, you too scared to ride with all the big scary cars?

Maybe that means ain't for you. Take it on the arches.

Spoken after no less than 7 years as a bike messenger, and after vowing to respect the rules of the road at year 5. Plus, I surbived with blimminal blain blamage.

Anonymous Coward

They just need to make them with bigger wheels, so you can stick some playing cards in the spokes. Problem solved.

JimC

Playing cards? Spot the posh rich kid.

Tom 7

Playing cards? Fucking walking stick mate!

The engine sound from Amiga Lotus Turbo Challenge II.

When you turn it on, it can play the theme music.

(first thought was benny hill theme music, already mentioned, and then the screams of souls eternally trapped in hell, but I guess partially covered by the poll).

Normal bicycles are silent, and can go pretty fast too. Why can't the same solution be used for e-Scooters, a bell?

Have you heard the Get-Ir e-Mopeds? No, just a faint whirr, and again, no problem there apparently.

Just the singling out of e-Scooters, because they're more affordable to the common pleb. But I would support a lower max speed in consumer models (especially targeted at younger people who will use them on pavements).

Potential Noises

Wally Dug

In a similar manner to those "voices" that warn you of a reversing lorry, it could say

"Super Cool Hipster In Transit" constantly and if it goes faster, just say the initials in a higher-pitched tone "SCHIT".

Or:

"Arrogant bawbag approaching".

"Entitled to use the pavement whether you like it or not regardless of the law".

An old-fashioned "mee maw" police siren.

Various aeroplane engine noises, e.g. Spitfire and Messerschmitt Bf 109.

"Arrrrgh!!! Gerroutthefukinwayit'sgonnacrash!!!!"

Or Kryten complaining about having to change the bulb.

Re: Hilly from Red Dwarf

Boothy

Coincidentally, Robert Llewellyn who played Kryten (in later seasons), has a toob of you channel for all things electric, in relation to energy and transport, so cars, PV, and of course e-scooters!

(channel is 'Fully Charged' in case anyone is interested).

andy gibson

Needs a "Toast of London" spoken warning.

andy gibson

Curious as to why they need a noise, particularly as existing cycles and regular scooters don't make any. Plus the ones you can hire already have a bell or buzzer on them.

Plus…

Pink Duck

The legislation change coming Saturday means cyclists and e-scooter riders should give way to pedestrians, just as EV drivers tend to give way to blind people already.

Re: Plus… NOT

adam 40

Funny you mentioned that but I read this the other week

https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1037306/table-of-change-to-the-highway-code.pdf

and there is not ONE mention of e-scooters.

Looks like DafT have cocked up AGAIN.

JDPower666

I was about to point out the hire scooters in my town don't have any kind of bell or buzzer on them, then googled to be sure and apparently they DO. Yet I did all their tutorials prior to riding and there was zero mention of it, and on the couple of occasions I've used one I've never seen it (nor have I ever heard one make any noise). So perhaps they could start by informing users such a noise making device exists.

imanidiot

Just ban the fecking things already. I really don't see what good they do.

Neil Barnes

No need to ban them.

Just observe that as a motor vehicle, they should be used *only* on the road, properly taxed, insured, and MOT'd. And with all the usual penalties for misbehaving drivers, only possibly more so.

Oh, and to all those idiots that just dump the damn things in the middle of the pavement when they get bored with them... I' assuming salvage rights apply?

Easy come and easy go,
some call me easy money,
Sometimes life is full of laughs,
and sometimes it ain't funny
You may think that I'm a fool
and sometimes that is true,
But I'm goin' to heaven in a flash of fire,
with or without you.
