Ecoboost sound is NOT "Recorded/Pre-rendered"

[OppoLock]

How many threads are we going to have about this? Who was that guy that has been saying this same thing....what's his name, he's the guy that pisses everyone off, that arrogant prick from Boston that actually uses his real name and a real picture of himself...oh I guess when he said that magazine testers write for a living and possibly, just possibly the fused circuit that powers the radio could possibly power the sound attenuation unit. This is old technology that Toyota was playing with when I was in HS and TTL circuits were state of the art.

How would one power a speaker with two separate sources without them canceling or directly influencing the engine sound or song on the radio?

If it were operated through the sound system how come the engine sound does not stop when you turn off the radio?

As was said in the last two threads about this exact subject, it is simply cancelling the obnoxious harmonics from a 4 cylinder engine. They have weird frequencies that are high in amplitude, it sounds boomy etc. Ford is just trying to make the car less exhausting to ride in....they are not trying to trick anyone, it's not a conspiracy. Yet we complain, again for the third time.

You don't hear these sounds in a V8 because of natural balance, of both audible and harmonic frequencies. As the OP said, this is basic, how do you guys struggle with basic science, I thought you were all engineers and shit?

It's more than just active noise control achieving select noise cancellation. Confirmed by Ford employee. There's playback of some sort, and it sounds more likely to be real time augmentation. Either way, there's both NVH reduction and additional amplification at play.

So the folks at Autoblog today asked Ford what the deal was, and here's what they uncovered:

Autoblog spoke with Ford engineer Shawn Carney who confirmed that only the turbocharged four-cylinder Mustang comes with this system, called Active Noise Control.
In fact, Carney is partially responsible for tuning and shaping the EcoBoost's note in the Mustang, and he said the setup serves two distinct functions. First, it cancels out some of the coarse noise as part of the 'Stang's refinement strategy.
It also allows Ford to enhance things by "layering in certain sound characteristics on top of what's already there," he said. To determine the right mix, the engine processor monitors torque output and changes things accordingly. "The intent is to be a natural experience," said Carney.

Side note: This guy driving, is a perfect example of why America needs to seriously look at it's driver education system. Did you see him twist his body to back out of the spot? How are you in control of an automobile positioned like that? Nice hands on the wheel too Brah. Let's apply a little more throttle before we actually release the clutch during the up shift, I ain't happy until I see green smoke dabnamit! I'm happy I ordered my Mustang with a couple of mirrors so I can back up like a proper driver.

I blame it on his long hair

And skinny jeans......

Back in my day, you were supposed to put your right arm on the passenger seat headrest and turn around while backing up, so, you know, you could see properly.

LOL....How is he not in control? No one just uses mirrors entirely for going in reverse. I bet you even give a shoulder glance before you back up.

You must be one of those mirror-Elitists.

LOL small world, I have a connection in common with Shawn. I would love to ask him some real questions on how it works. I loved my old turbo 4 Fords but they sounded like they were going to come through the hood. I understand people like what they like but some people can't be happy. If Ford didn't do this then everyone would complain about that. The only difference between this and the GT is the GT is done 100% with air, where as the Eco tells the air what to do. I mean nothing by this but it makes me laugh that 50% on this forum ordered premium cars with all the nav, blind spot, reverse park etc, you have no problem putting your lives in the hands of a couple digital comparator circuits but the earth ceases to rotate when those same electrons make your 4 cylinder sound much less like a box of rocks. To each his own.

Guys ... Dave Pericak of Ford told us about this waaaay back in December 2013 when he said in an interview with Car magazine:

With the Ecoboost engine we have both active noise cancellation, and we also amplify the existing engine sound order. We don’t create an artificial sound, we don’t pluck one off the shelf, we bring in the real sound, process it, and play it through the car’s speakers.

It doesn't get any clearer than that.

Want to debate semantics, fine. But if you want to use the word fake to describe Ford's use of active noise cancellation on the EcoBoost Mustang, then I suggest you ensure your stereo's graphic equalizer or treble/bass controls are all set to zero. Otherwise, any amplification of frequencies from your CD, MP3, radio, or satellite would just be fake music.

Yes I am a mirror elitist, my body stays straight, my head stays straight, I am in the proper position to operate all the controls. The vehicle I drive everyday has two side mirrors, I have zero rearward visibility, other than down both sides. No back up camera. I manage to back up just fine. I've only ever hit intended targets.

So you think it's safer to turn your head to the left while travelling down the highway to look in the lane to your left before you change lanes? How do you see the car in front of you stopping during that 1 second that you could be reacting? :doh: BLISS/Cross traffic warning :doh:

Um...don't these all have reverse cameras? No need to turn around at all.

An amazing backup camera to boot

I think it's easiest to just say the Ecoboost motor receives Digital Processing before being played through the speakers, and let others decide their feelings on definitions of words like 'fake'.

Digitally Processed. /thread

Um, yes. There are angles you can't see with your mirrors while backing out of a parking space, and I ALWAYS glance over the shoulder (left or right) before changing lanes. If you're close enough to rear-end somebody in the half-second it takes to glance over your shoulder, you're too close.

Cameras which are great for seeing directly behind you. But which may not be so great for seeing the person at your 8 o'clock walking around to go behind your car as you reverse with the wheel locked left.

Or, you could keep a safe distance from the car in front of you so that you can safely glance to your left or right before changing lanes. Keyword: safely. You should do everything that you can to make the lane change successfully without cutting someone off and avoid making contact with a vehicle in front of you if they suddenly slam on the brakes. No tailgating, no problem. I've seen plenty of blind spots, even with blind spot mirrors.

Listening to those 2 WR recordings back to back what strikes me is not that the EB sounds noticeably phony but that it is too regular in its sound - the frequency cycle of the engine throbbing does not vary, the overall frequency mix stays very constant. It reminds me very much of good engine/exhaust audio in a car simulation where the tone produced has an invariant relationship with the engine RPM.
