Audi Gives Silent Electric Car Synthetic Sound

itwbennett writes "Audi's electric cars are quiet, maybe too quiet, which is why Audi spent 3 years creating replicated engine noise for its electric car models. We're so conditioned to the noise of an engine revving that a driver behind the wheel of a too-quiet car may not realize how fast he's driving, and a pedestrian relying on auditory clues may be unaware of an approaching vehicle, says Ralf Kunkel, Head of Audi Acoustics." Nissan's been on this for years (as has Honda); one day, you may only get to choose which noise your car makes, rather than whether it does.

    I live in downtown Seattle and sometimes the noise is a bit much. The worst are the hogs that are designed to be incredibly noisy. People need to WATCH where they're going (look both ways, morons) and LOOK at the speedometer. And no, I'm not moving to some suburb or the country. It's not a living nightmare or anything, but I hardly see any good reason, other than just supporting stupidity, to actually put work into creating noise.

      Two words: blind people.

      Or more elaborately, everyone who can hear uses auditory cues to navigate in addition to other cues. Electric cars are highly unusual in that they make much less noise than their internal combustion engine counterparts. Until silent electric cars are commonplace enough that the public is aware that the normal sensitivity of audition may be insufficient to navigate as a pedestrian, adding sound would seem to be a good idea on the whole. Of course, the flip side is that people who are spending their time buried in their hand-held devices and don't look up when crossing the road are more likely to be weeded from the gene pool by silent cars, and some might consider that a plus. Getting to the point above, though, there are many people -- millions in the US alone -- with low vision or blindnes for whom automobile sounds are critical in warning of impending danger. Adding a modest sound to quiet electric cars definitely seems a good idea for them.

      But if you really want to cut down on urban noise pollution, as your post implies, address trucks, buses, and construction crews. Non-electric cars just aren't that loud and motorcycles aren't that frequent. Try to talk on a mobile phone as a truck or bus drives past, though: it's impossible.

      Am I the only one who thinks it shouldn't take 3 years to figure out how to make a car produce engine noises?

      No, no you are not. When I read that, I thought, really? 3 years? Uh, lemme see... loudspeaker + audio source + the tachometer = programmable sound that varies with engine speed. Took me all of 10 seconds.
       

      So what sounds do you play (a normal engine whirr or a deep-throated big-block?)? How do you scale that sound with RPMs? How do you ensure the sound you're playing won't be irritating to everyone after a period of time?

      Even more important - how do you handle interior vs. exterior sounds? Car makers do NOT make the whole cabin soundproof - they actually do funnel some engine sound into the cabin. Do you play an "idling" sound? Do you consider the inside and outside to be separate sounds? Do you simulate gears (and if so, at what points? and do you base it on speed or RPMs or how the driver is pressing down?). And how does it sound in the rain/snow/sand/dirt?

      It's the whole UI thing - that takes far longer to do than the technical steps. Little things like where you put the speaker can have a huge effect - it tane turn a great sound into a muffled annoying rumble. Or the mixing of existing car noise (motor/controller whine, wind noise) may turn the noise into something horrible.

      Hell, there are apps for your phone that play back engine noiess, but the whole acoustic package has to be considered.

      Sometimes I think letting engineers have all the fun when it comes to design is part of the problem; they tend to forget Occam's Razor. Then again, with all the drive-by-wire stuff they're mucking about with these days, maybe I shouldn't be surprised the auto engineers forgot that, at it's base, a car is a mechanical device.

      Drive by wire has several advantages, including reliability, economy (cars are "twist'n'go" these days - the computer does all the necessary adjustments to ensure it can start in the harshest conditions with a simple twist of the key - no accellerator flooring/choke adjusting/etc), emissions, etc. Plus information sharing - the navigation system can do dead reckoning based on wheel motion, speed, the steering wheel position, etc when it loses GPS signal. Nevermind all the safety features that people love, and cruise control.

    Look at it this way, some one was just killed by a bicycle and the blind deal with those everyday and they are just as quiet. 99% of the people benefiting from the sound will in fact be people that can't be bothered to look first. I've had gasoline running cars that were silent enough I didn't hear them approach. There does seem to be a touch of insanity making regulations that require noise pollution. Whether it's hydrogen or battery electric motor driven vehicles are likely the future so are we now setting a standard that we are committing to a future of gasoline engine sounding cars from here on out? To me it seems a little like demanding cars make the sound of horse hooves a 100 years ago so people were more comfortable with the transition.

    • Vehicle noise inside the car - so the driver has a perception of how fast they are driving.

    In some newer conventional engine cars, you have to strain to listen for the engine, when its on a low speed. Are they going to now require that mufflers not cut out more than certain amount of sound?

    And at higher speeds, you're going to hear the sound of the tires on the road LONG before you hear the sound of engine, unless, again, the engine is an older one or the muffler isn't doing it's job correctly.

    Are they going to also require that bicycles have such noisemakers installed? What about motorized wheelchairs? Both can cause extremely serious injury to people when moving at high velocities.

    - shouting to warn others of the approaching vehicle
    - honking a horn or otherwise making noise to "warn" oncoming traffic at any intersection.

    The horse and buggy whip cartels also insisted that the automobile would "spook horses" and cause all sorts of problems. As it turned out, of course, the horses didn't give a rat's ass about the cars, they were more likely to spook because some idiot hitched up a mare in heat and some other idiot had an un-gelded stallion on the rein, or because some asshole shot off a gun near them.
