Autoneum Launches Measurement System for Vehicle Acoustics

Autoneum, an automotive component manufacturer, has launched a new measurement tool called ATLAS (Airborne Transmission Loss Analysis System). ATLAS measures the acoustic insulation and transmission loss of components such as carpets, inner dashes and floor insulators. This allows customers to assess noise-reducing parts within minutes and select acoustic components tailored to their needs.

ATLAS sets new testing standards in this regard. While developers previously had to analyze the NVH behavior (noise, vibration, harshness) of interior parts using material samples of around one square meter in size, ATLAS makes this process faster, cheaper and more environmentally-friendly. It enables measurements of small samples with a diameter of no more than ten centimeters, which substantially decreases the amount of material used. Thanks to its four highly sensitive microphones, only two trials are required to collect precise and valid test data, making the system developed at Autoneum’s research center in the Swiss city of Winterthur especially suitable for quality assurance and repeatability of the results obtained. Users also benefit from time savings of up to 50% compared to the previous testing standard.
