Both legislation and customer demand set stringent requirements for exterior and interior noise of machinery and vehicles. Passenger and operator comfort, detectability, occupational and environmental noise requirements challenge the designer to reduce noise levels without conceding on other design constraints such as cost, weight or performance. TNO provides expertise and tools to deal with this.
TNO develops Active Noise & Vibrations Control (ANVC) systems for specific applications including passenger compartments, enclosures, panels, isolators and machinery components. Several patents have been granted and modular control software and hardware are available.
For five decades TNO has provided R&D and consultancy services to navies and commercial shipbuilding industries. A wide range of analytical, experimental and computational knowledge and tools are available, and solutions include both passive and innovative active technologies to isolate noise sources.
