It is not just the premium leather upholstery of car seats. Instead, many factors work together to achieve in-cabin comfort. Road noise cancellation is among those factors. In the early days, noise cancellation in cars was achieved by thickening window glass and windshields or by structural damping. Contrary to physical treatments, technological advancements in the automotive industry have now introduced systems for active road noise cancellation in cars.<\/p>\n\n\n\n

Let\u2019s take a closer look into what is active noise cancellation, its function and its benefits.<\/p>\n\n\n\n

What is Active Noise Cancellation?<\/h2>\n\n\n\n

Active road noise cancellation in cars refers to the modern technology used to reduce unwanted noise from roads, engines, and tyres. The technology uses sensors and microphones to simultaneously pick up unwanted noise and create a cancelling effect.\u00a0<\/p>\n\n\n\n

It takes only about 0.009 seconds for engine or road noise to reach the car occupants. The noise cancelling system is highly developed, it reduces noise in even lesser time.\u00a0\u00a0<\/p>\n\n\n\n

The noise cancelling system can reduce the overall noise by 3 – 4 dB. The significant noise reduction helps in lowering the driver fatigue, experienced on long drives. A driver with little to no fatigue is better capable of tackling traffic fatalities. <\/p>\n\n\n\n

How Does Active Noise Cancelling Work?<\/h2>\n\n\n\n

The active noise cancelling technology uses a combination of microphones and sensors<\/a>. The sensors monitor the vibrations from rough road surfaces. In contrast, a sound wave of the opposite phase is generated to cancel the unwanted noise.<\/p>\n\n\n\n

The cancellation sound is played by the vehicle\u2019s sound system. The advanced sound system improves the performance of active road noise cancellation in cars by monitoring cabin occupancy. The active noise cancelling technology also balances car weight and overall driving dynamics to provide a premium driving experience.<\/p>\n\n\n\n
