Active Sound Design (ASD) is on the way to become a standard task of every vehicle development program. It is a mandatory feature as Advanced Vehicle Alert System (AVAS) in every electric vehicle. For interior vehicle noise it evolves into a regular

Automobiles should be as quiet as possible, so noise emissions need to be minimized and controlled. Polyolefin foams are ideal for efficient noise absorption and sound deadening systems in vehicles and play an important role to reduce the overall wei

Pedestrians can only safely cross the road before an approaching vehicle if the time remaining until the vehicle arrives at their position (time-to-collision, TTC) is longer than the time needed to cross. In real traffic, the sound of a vehicle provi

Im klassischen Entwicklungsprozess ist die Perzeption der Antriebsstrangakustik im Fahrzeuginnenraum erst bewertbar, wenn physische Prototypen verfügbar sind. Um bereits in frühen Entwicklungsstadien (wenn die ersten CAE-basierte Daten zur Verfügu

The precise modeling of the structural dynamic behavior of electrical machines is relevant for the analysis of the noise behavior. According to the state of the art, it is not possible to predict the mechanical damping of an electrical machine. There

Vibroacoustic metamaterials are a promising technology for broadband noise and vibration reduction, that can induce a stop band for vibrations in the frequency domain. Within the stop band no elastic wave propagation is possible. Individually designe
