Noise control in aircraft and motor vehicles. The principal aim of this collaborative program between Australian and Japanese research teams is to tackle the complex issue of using active noise control systems focussing "zones of quiet" at passengers in aircraft and motor vehicles. The work has important implications for increased comfort of air travel and a safer environment for drivers of heavy vehicles. The outcomes will be the development of "smart skins" for application to aircraft and veh ....Noise control in aircraft and motor vehicles. The principal aim of this collaborative program between Australian and Japanese research teams is to tackle the complex issue of using active noise control systems focussing "zones of quiet" at passengers in aircraft and motor vehicles. The work has important implications for increased comfort of air travel and a safer environment for drivers of heavy vehicles. The outcomes will be the development of "smart skins" for application to aircraft and vehicle cabin interiors to actively control of interior noise. This will be achieved by combining the Japanese team's "structural wavenumber sensors" and the Adelaide team's "virtual microphones".Read moreRead less
Virtual acoustic sensors for active noise control systems. Traditional active noise control systems achieve the greatest noise reduction at the microphone error sensor(s). It is often desirable to achieve the maximum noise reduction remote from such sensors. Virtual sensing technology, the focus of this application, has the promise to replace traditional microphone sensing by projecting the zone of quiet away from the sensor microphones and directly into the ear of the user of the active noise c ....Virtual acoustic sensors for active noise control systems. Traditional active noise control systems achieve the greatest noise reduction at the microphone error sensor(s). It is often desirable to achieve the maximum noise reduction remote from such sensors. Virtual sensing technology, the focus of this application, has the promise to replace traditional microphone sensing by projecting the zone of quiet away from the sensor microphones and directly into the ear of the user of the active noise control system. This will revolutionise the sensing used in active noise control systems, and in doing so allow the realisation of active noise control in applications that have previously been infeasible.Read moreRead less
