EU Laws Requiring Audible Warning Sounds For Electric Cars Take Effect July 1 273

Posted by BeauHD from the too-quiet-for-their-own-good dept.
Starting July 1st, electric vehicles with four or more wheels must be fitted with an "Acoustic Vehicle Alert System" (AVAS) if they want to be able to legally drive in the European Union. With AVAS, vehicles would make a continuous noise of at least 56 decibels if the car's going 20 km/h (12 mph) or slower. New Atlas reports: Designed to address the public's fear of quiet electric vehicles, the new laws require cars -- not motorcycles -- to make some kind of noise at slower speeds. The noise, which isn't prescribed to be any particular sound, must rise and fall in pitch to signal whether the vehicle is accelerating or decelerating.

Fifty-six decibels isn't particularly loud, mercifully -- it's about the sound level of a running air con unit or electric toothbrush. A diesel truck, for example, will make about 85 decibels when it passes, and the rules state that the warning sounds can't be any louder than 75 decibels, or about the noise level of a regular dinosaur burning car. So the AVAS systems will make no difference at all to people who walk around with earphones in. Jaguar has decided to go with a "weird kind of spaceship sound," while BMW has gone with something that sounds more like a traditional engine. Nissan "seems to have gone for a bit of a jet airliner feel," writes Loz Blain for New Atlas.

      Ahem, at least some of the higher tier European car makers, like Porsche, have added artificial engine sounds a while ago.
      I've seen their soundlab for engine testing in the Weissach development centre, when we visited it with our control systems engineering professor in the mid 2000's (focus was on the bus systems used in Porsches).

      So why did they do this? Allegedly, because the customers complained that the new cars didn't sound like the old ones. So they always try to replicate the authentic Porsche sound with artificial means if necessary.

      A common complaint from regular people I hear around my (South Western) parts in Germany is that electric cars are too silent.

      Therefore I think that at least a subset of people has gotten used to the noise as a warning sign for an approaching motorized vehicle. It's not simply bureaucrats who came up with this. It wouldn't surprise me if it was the German MEPs who pushed this.

          They test for both interior and exterior sound from the setup I've seen. The anechoic chamber is large enough to fit even the largest Porsches, some high end microphones, high speed cameras (for test with just engine blocks if I remember correctly) and still leave plenty of room to walk around the setup.

          But yes, without a doubt the primary concern is the driver. They are the ones who (usually) pay for those cars.

        • Wow. 2 for 2. It's the second time you made silly assumptions about what "artificial sound" is being talked about rather than actually researching the topic. There are precisely zero electric cars on the market that put sound into the engine cabine, something traditionally done by muscle cars.

      You are aware that stuff like this tends to happen because of dead people, right?

      It's not some bureaucrat sitting around with too much free time and coming up with weird laws to pass. But that somebody got run over by an electric car, didn't like it, and went complaining to their representatives. And the representatives want to be seen as doing something, so they do.

      So, if you don't like this kind of thing, pass it around: if you or your mate gets run over by a silent car, don't complain! Tell them broken bones and dead people are a good price to pay for not having more regulations.

      At least the first video, was all about the blind. Same concept as those beeping crosswalks.

      I think I don't mind this as a transitory thing. For example, I can see it being an issue when you have both petrol AND electric cars on the road. In such a case, gas cars might mask the sound of an electric nearby.

      (Someone commented on how quiet some petrol cars are, and indeed some are! Yet.. there are a lot that aren't, and a lot of older ones that aren't)

      So, I'm all for this "for now". And really, you mention noise? Even those crosswalk "BEEP BEEP!" sounds will need to be tamed down a bit, once all gas cars vanish! They're made loud enough that when traffic goes roaring away from the opposite direction, they can be heard. Won't be necessary as much with all electrics.

      Hmm.

      You know, a final thought. There are going to be a lot more people mad at their neighbours. I live in the country, and I can hear my neighbour get into his car, and drive away.. and that's on 1 acre lots, and trees between us and so forth. I can hear him shut the door. I hear every car drive by on the road.

      Why? It's VERY QUIET out here.

      So when all petrol cars are removed from the equation, and the city becomes much more quiet, noise from neighbouring apartments and homes will become much, much more audible. And more so, without the constant 'hum' of cars and such, the 'peaks' of noise.. it being quiet, then BANG! really loud, will be much more intense.
