And here is where another GM division is heading with audio/sound management: http://m.digitaltrends.com/cars/all-...logy-of-sound/

In other venues where this has been attempted or simply used as an audio effect, it's been called 'frequency dependent compression.' The ultimate result is lowered dynamic range, which kind of defeats the purpose of why we went digital in the first place.

At any rate, any kind of signal compression (analog context, not digital) contributes heavily to listening fatigue. If you're not sure what we're referring to in listening fatigue or analog compression - it's the same technology and phenom that makes commercials sound louder than title program material on TV. And DEciiBel is absolutely correct (as expected) that the potential for the overall perceived sound in the cabin overall to become more fatiguing and even annoying by ultimately raising the offending frequencies, music or otherwise.

My point here is not to bash the system but instead to raise awareness and provoke questions. At the end of the day, it's all subjective and you'll be able to make your own choices soon as the cars are all but on their way. (That's exciting stuff right there!)

Please tell me the Corvette team is not going down thise road of "pumping" engine sound into the car through the audio or other system. That's just stupid, and it sounds fake. We don't need more fake garbage on the cars.

If the manufacturers feel the need to do this, then they need a better sounding engine and mufflers.

I agree completely Michael. We don't need the modern version of a playing card hitting bicycle wheel spokes. I think the C7 is safe from this audio enhanced engine sound effect.

This engine sound voodoo and the probable one year only use of the Aisin 8 speed auto has me rethinking replacing my 08 CTS with a new CTS V-Sport and looking at BMW instead.

They don't pump sound in to be corny, they do it because the engine sound is so muted due to sound deadening hat it is hard to hear when shifting and racing. Porsces and M5’s do it too and they don't need corny crap.

Bose is using the same tech they have been for years now and honestly I don't know why more Manufactures don't implement sound cancelation tech. Now about pumping the engine and exhaust tones through the audio system I will say that's a negative bravo leader, do not want!

Spulbus2013

The M5 has been laughed at for doing this by tons of people, Just cause BMW does something doesn't mean we should follow as some ideas are best L4D! HAHAHA!

Maybe it just comes with the upgraded stereo which is only offered on the 2 and 3.

So, if my wife is talking to me while I am..........

I too, hope they didn't try to compensate by amplifying specific frequency bands. Cancellation, even in a physically static environment like a car is precarious at best and at worst you can get standing waves that could effectively double the noise you are trying to cancel. Cars, especially loud, light weight cars are a pretty harsh environment if you want all of the dynamic range subtleties and frequency range to come through. The best environment to get those is a quiet environment, not a Corvette or Ferrari. I just hope they didn't F it up by being clever.

You know what they are pumping in? The sound from the intake. That won't help you at light load, which is where you would need it most based on your statement about sound deadening.

The Mustang GT has this, too, and it sounds really fake. I yanked it off, and it sounded better without it. I've heard the 911's, and it sounds just as fake.

No thank you to this cornball cr@p. I want to hear the engine, not some simulated engine.

This is only a concern if you are ALSO using the new iPhone 5s with finger scan.......

ANTIVNOM

any idea if this system has an off button? Not because I wouldn't want it, but just to see what difference it makes off vs on.

Hi,
Im having a aftermarket sub put in, using VetteNuts sub box ( thanks Mark). I was told in the menu, you can turn off and on the noise cancelling feature. Can someone explain, where I need to go to do this? I need this off for my new sub getting installed.
Thanks, Jerry

I think you're talking about audio pilot, you can turn that off in settings. I can't remember exactly how to get there, it's in the infotainment manual. That's the only thing I can think of.

Lyons16

Thanks, he said noise cancelling, I will confirm exactly what he means.
Thanks, Jerry

I have a 2014 3LT. All that I could find in the manual is Bose AudioPilot Noise Compensation Technology. Is this the same as the noise cancellation that you are talking about. If not, does the 2014 have this feature or is it only on newer year models?

The way I've always heard it is that white noise is all frequencies in equal amount (http://whatis.techtarget.com/definition/white-noise) therefore white noise would only serve to cancel all frequencies if the mere generation of white noise could "cancel" anything. No, noise cancelation is the process of sending out frequencies in reverse phase.
