Noise inside the vehicle cabin can be distracting, annoying or just plain tiring. David Brown reports on a new development
Hyundai has developed a Road Noise Active Noise Control system to dramatically reduce noise within the cabin of a vehicle.
It is a noise cancelling system that Hyundai says has been developed beyond existing systems which are limited to the number and variations of noises it could affect.
For example, there are different types of road noises that the new technology can process, such as resonant sounds created between tires and wheels or rumble sounds coming up from the road.
One of the interesting benefits is that traditional sound damping methods such as insulation and dynamic dampers fail to block the buzzing infrasounds completely but also adds more weight than this electronic alternative.
David’s boyhood passion for motor cars did not immediately lead to a professional role in the motor industry. A qualified Civil Engineer he specialised in traffic engineering and transport planning.
What followed were various positions including being seconded to a government think-tank for the planning of transport firstly in Sydney and then for the whole of NSW. After working with the NRMA and as a consultant he moved to being an independent writer and commentator on the broader areas of transport and the more specific areas of the cars we drive.
His half hour motoring program “Overdrive” has been described as an “informed, humorous and irreverent look at motoring and transport from Australia and overseas”. It is heard on 22 stations across Australia. He does weekly interviews with several ABC radio stations and is also heard on commercial radio in Sydney.
David has written for metropolitan and regional newspapers and has presented regular segments on metropolitan and regional television stations. David is also a contributor for AnyAuto
