brightspark Posted September 24, 2011 Share Posted September 24, 2011 So what does Culture Club, The Clash and the Beach Boys have to do with Electric Cars? You know the "zero emmision" vehicles that are going to save us from global warming/next ice age/etc while taking us to Tesco. Well the answer is Steve Levine who is a record producer for the above pop beat combos. The story in the latest edition of the Engineer (19/9/11) is that he is working on the HALOsonic project with Harmon and Lotus. Apparently, there is a concern that as electric cars are silent(?) Pedestrians (especially the visually impaired) might not hear them coming. So this project is working out what noise an electric car should make. Apparently noise "forms part of the sensory landscape" i.e. gear changes, sharp engine note rise as the car accelerates etc. It is antispated that there will be an opportunity for after sales sounds especially among the boy racers. So I was thinking...what sound do you want your electric car to make? Link to post Share on other sites More sharing options...
Guest Posted September 25, 2011 Share Posted September 25, 2011 An Ivor The Engine sound appeals to me. At least it would for about a minute after which it would be very very annoying. I think everything will just end up making a discreet hum after the first irritating-car-ringtone related murder occurs. Link to post Share on other sites More sharing options...

pete_mcfarlane Posted September 26, 2011 Share Posted September 26, 2011 I'd imagine most of the drivers would want their electric/hybrid cars to play a prerecorded lecture to the rest of us on how we should all drive electric/hybrid cars to save the planet.

RMweb Gold The Stationmaster Posted September 26, 2011 RMweb Gold Share Posted September 26, 2011 They certainly count as 'silent but deadly' as far as I'm concerned - a Prius reversed out of a space in the local surgery car park the other week and thanks to an idiot driver who didn't bother to look nearly hit a couple of folk who weren't expecting a moving car. And one passing in a local car park seemed just as dangerous with not a sound coming from it. So I reckon they do need a sound card and a suitable 'punishment' would be the sound of a Fordson Major running on TVO or a single cylinder stationary engine. I don't go along with the Class 37 noise because if you heard one of these cars in a station car park the potential excitement arising from confusion for us 'more mature' folk could lead to other problems.

RMweb Gold Oldddudders Posted September 26, 2011 RMweb Gold Share Posted September 26, 2011 I still think hybrid is the way for the foreseeable future, so an IC engine would still be part of the package. In the recent American Le Mans Series race at Laguna Seca, the fastest GT car (it wasn't eligible for points or a placing) proved to be a Porsche 911 GT3 with added electric motors. I believe it refuelled twice during the 6-hour race, i.e. using half the fuel of others in the class. Let's keep the petrol engine for the noise and add the motors for economy.

They need something- I'm old enough to remember Cardiff Trolleybuses, and recollect my little sister almost getting run over because she didn't hear one approach. Given the seeming profile of the Prius driver, perhaps a continually-repeating ' Caution, self-righteous prat approaching' loop could be played... 1 Link to post Share on other sites More sharing options...

But even a modern petrol engine running at tick-over wouldn't make much noise and certainly wouldn't rev in a way that attracts attention. The menace of the Prius lies in its low speed manouevring when by implication the petrol engine isn't running (unless the batteries have drained down too far to provide power). Once you start using the petrol engine as a noise generator you start to undermine the fuel saving because you'd be running it when it isn't needed. Picking up Brian's point it's quite noticeable round here that those driving a Prius do seem to come from an identifiable type although I'm not entirely sure if his suggestion is quite on target. Personally I prefer the occasional Ferraris I see in Tesco's car park as you can very definitely tell when they are moving Link to post Share on other sites More sharing options...
34theletterbetweenB&D Posted September 27, 2011 Share Posted September 27, 2011 I am pretty sure that no added noise is needed. There are several near silent road users in current use; milk floats, pedal cycles, some exceptionally quiet cars like Lexii, in addition to hybrids running on batteries. As the proportion of near silent vehicles on the road increases, the population as a whole will become aware of the need for a complete visual check, and not to depend on audibility to go short on looking first in all directions. When it is considered that people are regularly struck by noisy IC engine vehicles, sonic output is no certain protection. The additon of silent vehicles to the mix should - perhaps counter intuitively - improve matters, as it will force people into making a visual check in areas where road vehicles may be moving.

298 Posted September 27, 2011 Share Posted September 27, 2011 I'd want mine to sound like a Stuka Dive-Bomber.... ....or just it's natural quiet noise. If the motor car had been silent from the start, would it have been engineered to be audible, or just made do with a simple horn...? Perhaps some need to be reminded who the infallable one is in a person-car intereaction. Link to post Share on other sites More sharing options...
RMweb Gold Oldddudders Posted September 27, 2011 RMweb Gold Share Posted September 27, 2011 Perhaps some need to be reminded who the infallable one is in a person-car intereaction. Sadly the courts and insurance companies tend to take the view that the pedestrian is almost always the innocent victim, irrespective of his/her actions prior to meeting the car.

RMweb Premium Welly Posted October 1, 2011 RMweb Premium Share Posted October 1, 2011 Fit a DCC sound chip blown with 4VEP noises into any electric jalopy I own! I'll have the air compressor sounds going when I'm at the lights... Link to post Share on other sites More sharing options...
