Default "Sound Generator" on GTI. Preposterous.

Found this thread on vwvortex regarding a sound generator called Soundaktor on the 2011+ GTI. Supposed to generate rattles via ecu during throttle. I'm having trouble deciding what's worse: A fart cannon or this hockey-puck looking device generating artificial noise. Instead of tuning the car to produce a decent exhaust note, they use that piece of crap. Unbelievable.

The BRZ/FR-S has one.

The Z4 has one.

MINI has them on all of their cars.


Totally unbelievable


It's for intake noise.. not exhaust... and a loud intake is loud outside the car. It attracts unwanted attention and annoys people. The little noisemaker at the cowl brings in a tuned sound to the cockpit without disturbing people on the street.

Correct. But pre-2011s had an actual noise pipe which accomplished the same thing. I had no idea all those cars had a noise generator. I still don't understand the purpose of generating artificial noise from such a device. Might as well have an auxiliary channel for some extra noise. I guess it doesn't bother you. Auxiliary channel. Crank up the volume. VROOAAAAR.

Simples. People want silence when they're cruising on the highway, and they want a car that goes vroom vroom when they're racing in a school zone. Unfortunately, engines don't work like that.

Worse still, engines don't just go vroom vroom, there's also lots of tick tick (injectors, solenoids) and whirr whirr (chain drives), so if you install a turbocharger that muffles the vroom vroom noises, you're left with a lot of tick tick and whirr whirr. And people don't like that.

Oh man I saw the review on Top Gear. The sound comes from the speakers.

That is just funny... cheezy...

But never a less, M5 is sweet.

Due to the much stricter noise laws in other parts of the world (Namely the EU) it's a way to enhance the exhaust note (mostly to make it louder, and they can acoustically tweak it a bit too) to the driver without having to actually make the car louder on the outside.

The new 5.0L Mustangs have them. Most run a tube connected to the intake around the dash, but the Mustang ran a small pipe from the exhaust. It's a neat idea to solve the problem when you think of it.

The VW system is very different than that in the mustang. The VW plays a sound file stored in the ecu during certain acceleration events* through a dedicated speaker in the engine bay.

*Paraphrased from vwvortex, sounds like its actually played all the time.

Might as well put on of these in...


"Imagine starting up your modern, boringly silent car and the interior is filled with the thrilling sound of a powerful Super Sports Car engine…Shift in the first gear, hit the gas pedal and the driving experience will really thrill you! In every phase of driving - accelerating, decelerating, shifting, cruising and idling — the sound is so convincing that it actually fools your senses to believe that you are driving the real thing, a Super Sports Car!"

Those cars have a pipe that allows sound into the cabin. This is a speaker that plays vroom vroom noises.

Just imagine if you had both. Fake engine noises and a magic noise pipe. I think we are on to something..

Kind of dumb, but whatever.

Maybe BMW should put one in the 328i but with six-cylinder sound, for the people who are whining about how the new 2.0-liter four-cylinder sounds boring despite being better than the outgoing six in numerous ways.

Yes, the M5 has what is probably the worst incarnation of all of these fake noise crap. It simply plays synthetic exhaust note through the usual interior speakers.

One more reason to go for the upgraded sound system I guess.

Also I bet you can reprogram the ECU to play other exhaust noise.

I want 458 italia noise one day, maybe lambo another.

You're onto something... maybe have in-car Pandora with car sounds instead of music.

My dad bought a 2012 GTI the week before I ordered the WRX (he bought the one I went to test drive ).

I read about the sound generator shortly after he bought it. I mentioned it once but he didn't believe me. Later that week I researched it and found it to be true. I haven't had the heart to tell him

Ok so the rest of the cars that CalamityJesus named have noise generated by noise pipes, like I said for the pre-2011 GTI? That borders on retarded in my book, but the actual Soundaktor speaker is what I find the most absurd. If the car doesn't naturally generate the noise, I don't see why you'd want to hear it from a hockey puck. Looks like most of us are in agreement.

lol this is completely retarded.

I wonder if when these companies will make electric cars if they will have the radio play fake engine noises.

There are already proposed, possibly enacted regulations about electric cars generating sound externally, to prevent blind pedestrians from being caught unawares of silent-running electric cars.

playing a sound internally is probably not an unconsidered possibility, either, even if it's the jetsons' puttering sky-car sound, or whatever.

Thumbs down Automotive Travesty

The "Soundaktor" is essentially a vibrator the size and shape of a hockey puck. From what I've read, It does not play "sound files" from the ECU. It just vibrates based on ECU feedback. That sound will resonate throughout the car, and particularly the cabin. It comes on the MK6 (2011+) GLI, GTI and likely the Beetle Turbo.

Piping engine noise into the cabin is one thing. It's cheating - marginally. Ford does this on at least a few of their vehicles (Mustang, F150).

The Soundaktor device, however, is an automotive dildo. On vwvortex.com, there's a giant (stickied) thread about Jetta MK6 rattles, 1/4 of which will be solved by removing the Soundaktor. (The other 3/4 will be solved by not building the car in Mexico.) Everyone who removes the device is assuaged by soothing silence.

Egg on face for VW after all their "un-pimp ze auto" commercials. What were they thinking? And perhaps more importantly, what drugs were they on?

Next up: VW MK6 2013. Fake blow-off valves for everyone! http://www.akamoto.co.uk/dump-valve.asp

But WAIT! The best part is, there's an AUDI logo on the Soundaktor. It's an Audi part!

And then BMW's new M5 proves that no manufacturer is sacred anymore...

Mini Coopers are manufactured by the BMW group. Not surprised they get fake sounds, if they're willing to do the same to the M5(!) in the first place.

Egg on face for serious consumers! And I thought Fuji Heavy was an arrogant company.

Now let's spend millions more re-creating those sounds that were just removed by our new technology! We have to justify this by saying it's for blind people, which represent 0.001% of our population. Now, let's enact it into law to make sure all electric cars make sounds!

I think you're a little confused. Highway noise is tire noise, so electric cars do not solve this problem at all.

Sound generators will be used at low speeds (where there's virtually no tire noise). A 4000 lb vehicle that you don't hear at low speeds isn't just a problem for blind people, especially in situations where cars and pedestrians share the same space (like parking lots).
