Perforated flat absorbers for efficient noise minimization

Space-saving acoustic solutions by Sekisui Alveo for automotive applications

Lucerne, May 26, 2011 – Noise emissions are an important issue for automobile manufacturers: On one hand, they are legally required to comply with low limit values, and on the other, acoustic insulation increases the comfort of vehicle occupants, and thus serves as a sales argument. When choosing an absorber system, outstanding insulating and mechanical material properties play a decisive role for the manufacturers, but increasingly often so does available space. Sekisui Alveo, manufacturer of polyolefin foams, has optimized the acoustic properties of its products through modification and special treatment. The new flat absorber made of micro-perforated Alveocel foam efficiently reduces noise emissions in the engine compartment and meets the need of the automobile industry for space-saving solutions.
