The application which is addressed is a station-wagon for which an active road noise cancellation system by active vibration control techniques at the suspension-car body connection is developed.K. Wyckaert1996 International Conference on Noise and Vibration Engineering (ISMA 21)...
The resultant reduction of the road noise provides a considerable enhancement in the noise comfort of the estate car. 展开 关键词: Active noise control Road vehicle noise Transportation noise Acoustic noise Coherence DOI: 10.1121/1.425970 被引量: 2 ...
The active road noise cancellation reduces overall sounds by 3-4dB. This reduction is equivalent to reducing the volume of the sound system by four steps. In general, you won’t believe tires and road creates that much sound right? But the fact is they do. They produce lots of noise. F...
How the Harman solution works: the chassis of the vehicle is fitted with accelerometers; the system can measure the correlation of road vibration and resulting noise inside the cabin. An algorithm in the controller creates inverse sound waves coming from each speaker through the car's audio system...
In addition to Road Noise Cancellation, HALOsonic offersEngine Order Cancellation(EOC) andElectronic Sound Synthesis(ESS). EOC uses active noise cancellation technology to reduce the drone and rumble induced by the engine in the car cabin. It uses the engine RPM signal as a reference to generate...
The automotive giant has teamed up with audio experts at Harman International to launch the world’s first active noise cancellation system for a production vehicle. Much like sound-cancelling headphones that isolate the user from the outside world, the in-car technology c...
“But we know it’s much more difficult to control noise in a large space like a car cabin compared to the relatively small area around your ears. However, through research advances and our relentless efforts to solve tough problems, we’ve achieved a level of road noise reduction that ...

Electric cars inherently benefit from quieter operation, and the i7 enhances that natural advantage with state-of-the-art noise-cancellation technologies. Car and driver referred to the I7 cabin as “so quiet you could hear a pin drop!” Overall, the BMW I7 features a smooth electric ride ...
