When Road & Track’s Jason Cammisa busted a fuse during a recent drive
of the 2015 Ford Mustang EcoBoost, he discovered something odd. Both
the engine and the stereo went silent inside the car.

It appears that the vaunted Ford Mustang – “the original pony car,”
according to Jalopnik – has succumbed to piping in enhanced engine
noise through the speakers.

Autoblog investigated further, speaking to Ford engineer Shawn Carney
who revealed that the engine-sound augmenting system is called “Active
Noise Control,” and that only the turbocharged four-cylinder Mustang
comes with it. The system both enhances noise and cancels out some
coarse noise.

“[The system] layer[s] in certain sound characteristics on top of
what’s already there,” Carney told Autoblog. “The intent is to be a
natural experience.”

Have they no sense of decency, sir?

Merely a variation of the insanely popular custom of removing or
swapping out the muffler on Harleys to get that fart ripping sound of
(no) power. Whenever I reel one in and the owner desperately twists
his noise rheostat in a futile attempt to minimize his shame, I'm
momentarily forced to listen to all sixty five ponies bleating about
having to live under a jackass's crack. But hey, the owner's brief
glimpse of their do-rags in my mirror probably makes up for having all
the acceleration but none of the utility of a slant six Dodge Dart.

Scientific demonstration of the phenomenon.
