With Zeta-Light, Autoneum is adding an integrated damping function to fibre-based trim components such as carpets or inner dashes, significantly improving their acoustic performance.
Zeta-Light not only insulates and absorbs airborne noise, but also effectively reduces low-frequency vibrations of the car body, independent of temperature. In addition to improving the acoustic comfort of vehicle occupants, the new damping system also contributes to significant weight savings and simplified vehicle assembly.
To ensure a quiet and comfortable driving experience, car manufacturers rely on components that attenuate airborne as well as structure-borne noise in the vehicle interior. Zeta-Light, meets both of these acoustic requirements. The integrated particle dampers complement the sound-insulating and absorbing properties of fibre-based, lightweight and sustainable technologies such as Hybrid-Acoustics ECO+ or Prime-Light for damping the low-frequency vibrations of the vehicle body. Compared to conventional damping alternatives, Zeta-Light allows for the effective reduction of both noise and vibration in a wider frequency range and at lower weight and performance of the particle dampers is not affected by temperature.
Friction
Zeta-Light consists of small particles enclosed in thin nonwoven capsules and integrated into the car body side of noise-insulating components such as carpets or inner dashes. The capsule transfers the vibrations of the vehicle body to the particles and sets them in motion. Damping is achieved through collisions and friction between the individual particles.
Since the particle dampers are integrated into the back of the sustainable felt-based components, Zeta-Light also simplifies parts logistics and the assembly process as well as recyclability in production and at the end of the vehicle’s life.
Acoustics conference
Zeta-Light will celebrate its world premiere at this year’s Autoneum Automotive Acoustics Conference on July 11-12 in Zurich, Switzerland. The conference serves as a global forum for leading industry executives, developers and scientists and more than 20 acoustics experts will present relevant and up-to-date findings.
