Fake Engine Noise Is the Auto Industry's Dirty Little Secret 823

HughPickens.com writes Stomp on the gas in a new Ford Mustang or F-150 and you'll hear a meaty, throaty rumble — the same style of roar that Americans have associated with auto power and performance for decades. Now Drew Harwell reports at the Washington Post that the auto industry's dirty little secret is that the engine growl in some of America's best-selling cars and trucks is actually a finely tuned bit of lip-syncing, boosted through special pipes or digitally faked altogether. "Fake engine noise has become one of the auto industry's dirty little secrets, with automakers from BMW to Volkswagen turning to a sound-boosting bag of tricks," writes Harwell. "Without them, today's more fuel-efficient engines would sound far quieter and, automakers worry, seemingly less powerful, potentially pushing buyers away." For example Ford sound engineers and developers worked on an "Active Noise Control" system on the 2015 Mustang EcoBoost that amplifies the engine's purr through the car speakers. Afterward, the automaker surveyed members of Mustang fan clubs on which processed "sound concepts" they most enjoyed.

Among purists, the trickery has inspired an identity crisis and cut to the heart of American auto legend. The "aural experience" of a car, they argue, is an intangible that's just as priceless as what's revving under the hood. "For a car guy, it's literally music to hear that thing rumble," says Mike Rhynard, "It's a mind-trick. It's something it's not. And no one wants to be deceived." Other drivers ask if it really matters if the sound is fake? A driver who didn't know the difference might enjoy the thrum and thunder of it nonetheless. Is taking the best part of an eight-cylinder rev and cloaking a better engine with it really, for carmakers, so wrong? "It may be a necessary evil in the eyes of Ford," says Andrew Hard, "but it's sad to think that an iconic muscle car like the Mustang, a car famous for its bellowing, guttural soundtrack, has to fake its engine noise in 2015. Welcome to the future."

Comment Re:Time for a UNION! (Score 1) 271

That's a solution only if you accept the drawbacks of being a contractor. Suddenly you have to do acquisition, you're a business so your taxes get 10x more complicated (e.g. VAT), etc.

We're seeing some industries moving towards an all-contractor model over here (.nl). Postal delivery and the building trade for instance. Some contractors do well for themselves, but there's a large number of them subsisting below the poverty line. As a contractor they're no longer protected by employment laws so they get screwed over no end. Especially in the building slump of the past few years people were agreeing to work for a pittance, not realizing the consequences in time. And if they don't get a contract, they're business owners so not eligible for unemployment benefits either. Meanwhile the contract prices are under pressure as workers from low-wage countries migrate here and accept conditions that result in a wage that is livable in their home country, but not here.
This is a gigantic poverty trap, and an end run around employment law and the unions by building companies. IMO a service/contract culture is not something we should wish for.

Comment Not as efficient: TFS is wrong (Score 2) 65

TFA says: "Using a light beam to charge a smartphone could be as quick as many wired chargers, the researchers found, depending on the size of the PV panel."

Efficiency is going to depend on the efficiency of the PV panel in the phone, but at 20% it's a long way off from the efficiency of a wired charger.

The lengths to which people will go to avoid plugging in a wire still amaze me.

Microsoft Researchers Use Light Beams To Charge Smartphones 65

angry tapir writes A group of Microsoft researchers has built a prototype charger for smartphones that can scan a room until it locates a mobile device compatible with the system and then charge the handset using a light beam. The researchers say they can achieve efficiency comparable to conventional wired phone chargers. The biggest barrier? Smartphones don't (yet) come with solar panels attached.

The main hydraulic system on the F9 (for gimbaling the engine nozzles) uses RP-1 (i.e. rocket fuel) as its hydraulic fluid. Spent fluid from that system goes into the fuel tank.
The fins are driven by a separate system at the top of the stage, if they pumped the spent RP-1 overboard you'd have flammable liquids running down the stage, I'm pretty sure they don't want to do that. Returning the RP-1 to the fuel tank is unlikely (needs an insulated pipe around the outside, next to the cold LOX tank). So probably a separate waste tank near the fins.

Could you please let me know which Govt Department I go to in France to apply for the location I am allowed to live in?
I seem to be having trouble finding it - hell - last time I was there I just lived where I damn well wanted to and could afford..

The word 'afford' is key here. If all you can afford is the lowest-rent housing, then that's where you end up. That's how many large European cities ended up with immigrant ghettos.
