Altogether, 368 deliverables and 231 milestones were made over the full project. The results clearly indicate the potential of active systems and intelligent materials systems for active noise control in a sustainable lightweight design. In the technology areas major progress and breakthroughs have been realized with respect to performance of the material and actuator systems, manufacturing, control strategies and electronic components suitable for the intended applications. Furthermore, for the first time detailed investigations on the reliability of such systems were conducted demonstrating that the standards and requirements of the industry can be met. Besides, cost effective design tools were developed and validated allowing a much more efficient design of active systems within development process of the industry. Regarding the applications scenarios, for all considered benchmarks the feasibility and potential of active systems for a noise reduction on 10 dB or more has been proven. The validation of the concepts resulted in laboratory-scaled demonstrators up the implementation and demonstration in vehicles. A brief overview of selected, highlighted results is given in the table below.
