Apamat II
Testing Acoustic Treatment: A Simple Test of Effectiveness

Apamat II was designed in order to compare and classify the complex range of soundproofing solutions currently used in the automotive industry. Apamat II tests the effectiveness of noise protection components and materials in terms of noise control, noise damping and noise insulation using just one system. Apamat II simulates
structure-borne and airborne excitation of the vehicle body-in-white under normal driving conditions. This realistic driving simulation enables valid and reliable measurement results to be obtained. Furthermore, the comprehensive suppression of secondary transmission paths in Apamat II facilitates a high dynamic range, making it particularly suitable for measurements of modern, high-performance noise control components.

Apamat II offers:

  • Develop of new materials and concepts
  • Measurement of acoustic efficiency by simulating material performance in the vehicle
  • Measurement of noise control, noise damping and noise insulation using just a single system
  • Combination of structure-borne and airborne excitation
  • Quick and easy measurement
  • Extremely robust, stable and durable system
