Autoneum unveils ATLAS acoustic measurement

Autoneum says with its ATLAS measurement methodology, noise-reducing vehicle components and materials can be analysed and developed faster and with a significantly lower need for resources in the future.

The newly launched ATLAS – short for ‘Airborne Transmission Loss Analysis System’ – 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.

While developers previously had to analyse NVH behaviour (noise, vibration, harshness) of interior parts using material samples of around one square metre 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 centimetres, which substantially decreases the amount of material used.

With 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 centre in the Swiss city of Winterthur especially suitable for quality assurance and repeatability of the results obtained.

The supplier maintains users also benefit from time savings of up to 50% compared to the previous testing standard.
