Fast Trim
The Fast Trim module helps users to evaluate the acoustic performance of multiple layers, like carpet, wood, or foam for absorption and transmission. Multiple layers are applied to a base structure. Results are given as complex frequency-dependent transfer admittances, which convey the local relation between pressure and velocity on both multi-layer sides: the cavity side and the base structure side. Results are used to assess the influence of multi-layered materials on the global acoustic system performance in, for example, vehicle and airplane interiors.
