Whether used for minimising background noise on a business flight, or silencing the babble of commuters on a train, noise-cancelling headphones have made journeys more serene and enjoyable for millions. Now, Ford has applied the same thinking to its cars.
Ford’s Active Noise Control uses three microphones, strategically placed in the cabin, to detect undesirable noises from the engine and transmission. The system counteracts those noises with opposing sound waves from the audio system – without affecting volume levels of music and conversation. Driver and vehicle behaviour is recorded and anticipated, for example when a driver is accelerating in a lower gear.
“Whether listening to a favorite playlist, tuning into a much-loved station, or simply enjoying a respite from the demands of modern life, the experience of sound – and just as importantly silence – can be a fundamental part of an enjoyable car journey,” said Dr Ralf Heinrichs, supervisor, Noise Vibration Harshness, Ford of Europe, “Our new Mondeo Vignale with Active Noise Control offers drivers enhanced levels of comfort, and fewer distractions.”
Active Noise Control is part of a range of innovations for the flagship Ford Mondeo Vignale that enhance sound quality. Another example is acoustic glass that can improve the sound-proofing qualities of the windscreen and front windows. Containing a layer of acoustic film thinner than a human hair, acoustic glass reduces the intrusion of wind noise caused by air flow around the window pillars.
“Noise is intrusive and reduces the driver’s mental processing power, and can lead to distraction and stress,” said Dr John Cartwright, chief medical officer, Ford of Britain. “By removing unwanted powertrain noise, Ford is helping customers to complete their journey calmly and in comfort.”
